Fatigue and tensile strength of dental gallium alloys after artificial saliva immersion. (1/201)

Fatigue strength using the stair-case method and tensile strength of dental gallium alloys after artificial saliva immersion were measured for evaluating the effects of corrosive environment storage on the mechanical properties of the gallium alloys. The fatigue and the tensile strengths of both gallium alloys stored in artificial saliva were significantly decreased after 12-month storage, while those stored in air increased with storage period. The fracture surfaces of the specimens in artificial saliva showed not only metallic luster but also dark areas. In the dark area, the matrix might have dissolved during immersion. These results suggested that the concern over corrosion resistance of gallium alloys still remained.  (+info)

The durability of parylene coatings on neodymium-iron-boron magnets. (2/201)

A parylene coating is frequently used to prevent corrosion of neodymium-iron-boron magnets when they are used intra-orally. This in vitro study was designed to test the durability of parylene coating in a simulated oral environment. Single and double parylene-coated magnets were subjected to grinding and crushing forces in an industrial ball mill. The results demonstrate that abrasion and wear was visible around the edges after 1 hour of testing, with a breach of the coating noted under high magnification scanning electron microscopy (SEM). The conclusion of the study is that parylene coating is unlikely to withstand intra-oral forces. The shape of the magnets, the manufacturing process involved in their production, and the thickness of the parylene coating are important factors to consider with respect to the durability of magnets used in the mouth.  (+info)

Isothermal age-hardening behaviour in a multi-purpose dental casting gold alloy. (3/201)

The isothermal age-hardening behaviour of a multi-purpose dental casting gold alloy was investigated by means of hardness testing, X-ray diffraction study, scanning electron microscopic observations and energy dispersive spectroscopy. By ageing of the solution-treated specimen at 400-500 degrees C, two phases of the Au-rich alpha 1 phase with an f.c.c. structure and the alpha 2 phase with an ordered f.c.c. structure based on Pt3In were transformed into three phases of the alpha 1 phase, the alpha 2 phase and the beta phase with an ordered f.c.t. structure based on PtZn. Hardening was attributed to the fine nodular precipitation resulting from the formation of the beta phase in the alpha 1 matrix. Softening was due to the coarsening of the fine nodular precipitates as the result of consumption of the alpha 2 phase.  (+info)

Surface characterization of retrieved NiTi orthodontic archwires. (4/201)

The structure and morphological condition of retrieved NiTi orthodontic archwires was evaluated and any possible alterations in the surface composition of the alloy following 1-6 months in vivo were characterized. NiTi wires (GAC, German Orthodontics, ORMCO) of various cross-sections were collected through a retrieval protocol and were subjected to multi-technique characterization. Optical microscopy revealed islands of amorphous precipitants and accumulated microcrystalline particles. Micro MIR-FTIR investigation of the retrieved samples demonstrated the presence of a proteinaceous biofilm, the organic constituents of which were mainly amide, alcohol, and carbonate. Scanning electron microscope and X-ray microanalysis showed that the elemental species precipitated on the material surface were Na, K, Cl, Ca, and P, forming NaCl, KCl, and Ca-P precipitates. Increased intra-oral exposure was consistently associated with the presence of a mature film, while evidence of alloy delamination, pitting, and crevice corrosion, as well as a notable reduction in the alloy grain size was observed. Intra-oral exposure of NiTi wires alters the topography and structure of the alloy surface through surface attack in the form of pitting or crevice corrosion or formation of integuments. Further in vivo research is required to resolve the implications of the described ageing pattern in the corrosion resistance of the alloy, the potential for nickel leaching, as well as bracket-archwire friction variants.  (+info)

The interaction of factors to cause the staining is discussed and it's prevention in future cases highlighted. Subsequent restoration of the affected teeth is shown.  (+info)

Influence of finishing on the electrochemical properties of dental alloys. (6/201)

Dental alloy surface finishing procedures of may influence their electrochemical behavior, which is used to evaluate their corrosion resistance. We examined the polarization resistance and potentiodynamic polarization profile of the precious-metal alloys, Type 4 gold alloy and silver-palladium alloy, and the base-metal alloys, nickel-chromium alloy, cobalt-chromium alloy, and CP-titanium. Three types of finishing procedure were examined: mirror-finishing using 0.05 micron alumina particles, polishing using #600 abrasive paper and sandblasting. Dissolution of the alloy elements in 0.9% NaCl solution was also measured and compared with the electrochemical evaluation. The corrosion resistance of the dental alloys was found to relate to finishing as follows: The polarization resistance and potentiodynamic polarization behavior revealed that the corrosion resistance improved in the order of sandblasting, #600-abrasive-paper polishing, and mirror-finishing. While the corrosion potential, critical current density and passive current density varied depending on the type of finishing, the transpassive potential remained unchanged. The influence of finishing on the corrosion resistance of precious-metal alloys was less significant than on that of base-metal alloys. A mirror-finishing specimen was recommended for use in evaluation of the corrosion resistance of various dental alloys.  (+info)

Corrosion resistance of the Pt-Fe-Nb magnets for dental-casting. (7/201)

Magnetic attachments have been used in clinical dental practice, but there is some difficulties associated with removable bridges. One possible solution is to make whole bridges of Pt-Fe magnet alloys and its abutment out of magnetic stainless steel by casting. In terms of castability and magnetic properties, the promising composition of the Pt-Fe-Nb magnet alloy is Pt-30.0 mass% Fe-0.6 mass% Nb and Pt-30.0 mass% Fe-0.5 mass% Nb-0.03 mass% Si. In the present study, the corrosion resistance of these alloys was investigated based on the elusion test, electrochemical behavior and surface characterization by EPMA analysis. The released elements from the Pt-Fe-Nb magnets were mainly Fe ions in quantities similar to that of stainless steel for biomedical use, and the Pt-Fe-Nb magnet alloy, the Pt-Fe-Nb-Si magnet alloy and platinum resembled each other in electrochemical behavior. The present findings suggest, that the Pt-Fe-Nb magnet alloy provides excellent corrosion resistance and has important clinical dental applications.  (+info)

Corrosion characteristics of ferric and austenitic stainless steels for dental magnetic attachment. (8/201)

The corrosion behaviors of four ferric stainless steels and two austenitic stainless steels were examined in a simulated physiological environment (0.9% NaCl solution) to obtain basic data for evaluating the appropriate composition of stainless steels for dental magnetic attachments. The corrosion resistance was evaluated by electrochemical techniques and the analysis of released metal ions by atomic absorption spectrophotometry. The surface of the stainless steels was analyzed by X-ray photoelectron spectroscopy (XPS). The breakdown potential of ferric stainless steels increased and the total amount of released metal ions decreased linearly with increases in the sum of the Cr and Mo contents. The corrosion rate of the ferric stainless steels increased 2 to 6 times when they were galvanically coupled with noble metal alloys but decreased when coupled with commercially pure Ti. For austenitic stainless steels, the breakdown potential of high N-bearing stainless steel was approximately 500 mV higher than that of SUS316L, which is currently used as a component in dental magnetic attachments. The enriched nitrogen at the alloy/passive film interface may be effective in improving the localized corrosion resistance.  (+info)

Corrosion Types of Magnesium Alloys | IntechOpenCorrosion Types of Magnesium Alloys | IntechOpen
Magnesium (Mg) alloys are susceptible to corrosion in aggressive environments. Corrosion of Mg alloys depends greatly on their composition and microstructure (grain size, the size, shape and distribution of second phases), post-processing and media. In most cases, localized corrosion, such as pitting corrosion and filiform corrosion, generally occurs due to microgalvanic corrosion between the intermetallic compounds and their neighboring α-Mg matrix. However, open literature reported that several corrosion morphologies, that is, intergranular corrosion (IGC) and exfoliation corrosion (EFC), cannot appear on Mg alloys. In this chapter, all typical corrosion modes of Mg alloys and influencing factors are introduced, including general corrosion, galvanic corrosion, pitting corrosion, filiform corrosion, IGC, EFC, stress corrosion cracking (SCC), corrosion fatigue (CF) and so on. The focus is laid on pitting corrosion and EFC. Corrosion mechanisms of Mg alloys are also discussed.

Corrosion Characteristics of As-Cast Aluminium Bronze Alloy in Selected Aggressive MediaCorrosion Characteristics of As-Cast Aluminium Bronze Alloy in Selected Aggressive Media
ABSTRACT. This research work investigated the corrosion characteristics of aluminium bronze alloy in four selected aggressive media which are H2SO4, HCl, NaOH, and NaCl. Aluminium bronze alloy was produced locally via sand casting method. Copper coils and aluminium materials which constitute waste to the environment were used in producing the alloy. Test specimens were produced from the as cast alloy and immersed in H2SO4, HCl, NaOH, and NaCl environment. The concentrations of the environment were varied as 0.1 M, 0.3 M and 0.5 M. The aluminium bronze produced from sand casting has mechanical properties that are closer to the standards proposed by CDA [1]. The corrosion rate was determined by weight loss method at an interval of 3 days. It was observed that the corrosion behaviour exhibited by aluminium bronze in acidic media followed similar trends in 0.1 M, 0.3 M and 0.5 M respectively. However, the corrosion rates increases with increase in the concentration of H2SO4 and NaCl media, but the ...

Indian Patents. 257259:A NAPHTHENIC ACID CORROSION INHIBITION COMPOSITION
While various corrosion inhibitors are known in various arts, the efficacy and usefulness of any particular corrosion inhibitor is dependent on the particular circumstances in which it is applied. Thus, efficacy or usefulness under one set of circumstances often does not imply the same for another set of circumstances. As a result, a large number of corrosion inhibitors have been developed and are in use for application to various systems depending on the medium treated, the type of surface that is susceptible to the corrosion, the type of corrosion encountered, and the conditions to which the medium is exposed. For example, U.S. Pat. No. 3,909,447 describes certain corrosion inhibitors as useful against corrosion in relatively low temperature oxygenated aqueous systems such as water floods, cooling towers, drilling muds, air drilling and auto radiator systems. That patent also notes that many corrosion inhibitors capable of performing in non-aqueous systems and/or non-oxygenated systems perform ...

Certain metal surfaces are often unable to be contacted effectively with fluids containing hydrofluoric acid due to significant corrosion issues. Steel surfaces represent but one example. Corrosion inhibitor compositions comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof can be used to suppress corrosion of steel surfaces, including those that contain multiple types or grades of steel. Methods for suppressing corrosion of a steel surface can comprise: contacting a steel surface with a corrosive environment, the corrosive environment comprising hydrofluoric acid; exposing the steel surface to a corrosion inhibitor composition, the corrosion inhibitor composition comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof; and suppressing corrosion of the steel surface being contacted with the corrosive environment through exposure to the corrosion inhibitor composition.

Localised corrosion and atmospheric corrosion of stainless steels | KTHLocalised corrosion and atmospheric corrosion of stainless steels | KTH
This research is focused on defining limiting conditions for corrosion of stainless steels. The aim of the first part (Papers I-IV) was to understand the role of alloying level and environmental parameters on localised corrosion in aqueous conditions. Testing was done with a combination of short-term electrochemical and long-term immersion experiments. Results show that the chloride ion concentration and temperature are the main factors that affect the localised corrosion resistance. The presence of residual chlorine is also significant, since it leads to the ennoblement of the corrosion potential. If the corrosion potential exceeds the breakdown potential, the stainless steel will suffer from localised corrosion. Oxygen content and pH were identified as additional factors influencing the corrosivity of the environment.. The aim of second part (Papers V-VIII) was to present information about the effect of alloying level, surface condition and environmental conditions on atmospheric corrosion ...

Biofilms cause various problems such as medical infections, fouling of water cooling system, product contamination, and microbiologically influenced corrosion (MIC). MIC accounts for as much as 20% of all forms of corrosion, amounting to billions of dollars in losses each year. Among bacteria related to MIC, sulfate reducing bacteria (SRB) are most often blamed. The ubiquity of these bacteria leads to a variety of impressive industrial, economic and ecological effects because of their proneness to generate large quantities of H2S. SRB are the main reason to cause the MIC by accelerating corrosion rate, inducing stress corrosion and pitting corrosion. The aim of this study was to evaluate the corrosion associated with the formation of SRB biofilms on carbon steel surfaces ...

OPUS 4 | Corrosion investigations on zinc coatings by using gel-type electrolytes
A new approach to the assessment of the corrosion behaviour of zinc coatings under atmospheric conditions can be achieved using gel-type electrolytes as an alternative to standard aqueous test electrolytes. Gel-type electrolytes allow minimally invasive corrosion investigations on zinc coatings. They also provide the possibility to carry out corrosion investigations onsite. By using gel-type electrolytes corrosion-relevant characteristic values such as corrosion currents and polarization resistances can be determined. These allow to describe the formation and the stability of the formed corrosion product layers under various climatic conditions. With this knowledge, a prediction of the zinc coating life cycle is possible. In this contribution, the value of gel-type electrolytes for corrosion research on zinc coatings is presented.

Recently, SiC-based ceramics have been found to exhibit corrosion damage patterns, which can only be explained by electrochemical processes. Therefore, the current work focusses on the electrochemical test procedures to determine the corrosion behaviour of solid state sintered silicon carbide (SSiC) ceramics in acidic and alkaline media. The corrosion current densities have been determined from linear voltammetric scans. At anodic polarization potentials, electrochemically induced etching patterns were observed in alkaline solution. The formation of pores and crevices during electrochemical oxidation in acidic solution could be monitored by field emission scanning electron microscopy (FESEM) in addition to transmission electron microscopy (TEM). Impedance spectra measured after anodic polarization could be described by the assumption of a pore model equivalent circuit. ...

In light water reactors corrosion-induced material degradation is a critical issue not only for material integrity but also for plant radiation field build-up. In BWRs nickel-base alloys, such as Alloy 600, Alloy 82 and Alloy 182, are applied in various parts of reactor components including welds. However, their corrosion mechanisms are not very well understood. Although the complex compositions of different nickel-base alloys generally prohibit us to single out some specific alloy constituent having a major impact on alloy corrosion rate, a higher chromium content is often thought to be beneficial to forming a more protective oxide film against corrosion attack. In this paper we report a corrosion kinetics study on high chromium nickel-base alloy welding consumables, Alloy 52M and Alloy 152, under simulated BWR normal water chemistry conditions and high flow velocity for up to nine weeks exposure. The corrosion rates are derived from measurements of weight losses of test coupons, oxide ...

Study of Preferential Weld Corrosion in X52 Mild Steel with the Presence of Acetic Acid - UTPediaStudy of Preferential Weld Corrosion in X52 Mild Steel with the Presence of Acetic Acid - UTPedia
Preferential weld corrosion occurs in the hydrocarbon carrying pipelines due to CO2 presence. The weld segments consist of parent metal, HAZ and weld metal that causes corrosion due to potential difference. The corrosion could be mitigated with the formation of protective layer (FeCO3). However, the mitigation has not been effective as the FeCO3 layer formation is disrupted by environmental conditions like the pH and also the presence of weak acids like Acetic Acid (HAc) The purpose of this research is to investigate the presence of HAc and its effect on the corrosion rate of the weld segments. The influence of pH on the FeCO3 formation on the weld segments with and without HAc present is also analyzed. A coupled sample and an un-coupled sample is prepared from the API 5L X52 mild steel weld segment. Test parameters were set to varying pH 4 and 6.6 with and without 1000ppm HAc present. 4 glass cells are set up to measure the intrinsic corrosion rate of the un-coupled sample and 4 glass cells are ...

Corrosion product formation during NaCl induced atmospheric corrosion of magnesium alloy AZ91DCorrosion product formation during NaCl induced atmospheric corrosion of magnesium alloy AZ91D
The low density and high specific strength of magnesium alloys have created a great deal of interest in the use of these alloys in the automotive and aerospace industries and in portable electronics. All of these industries deal with applications in which weight is extremely important. However, an obstacle to overcome when using magnesium alloys in engineering applications are their unsatisfactory corrosion properties. This thesis is devoted to the atmospheric corrosion of the two magnesium alloys AZ91D and AM50, in particular the ways the microstructure and exposure parameters of these alloys influence their corrosion behaviour. The work includes both laboratory and field studies. The results obtained show that the microstructure is of vital importance for the corrosion behaviour under atmospheric conditions.. The microstructure of magnesium-aluminium alloys contains different intermetallic phases, e.g. Al8Mn5 and β-Mg17Al12. The local nobility of these intermetallic phases was measured on a ...

Metals | Free Full-Text | Corrosion Protection of Electrically Conductive Surfaces | HTMLMetals | Free Full-Text | Corrosion Protection of Electrically Conductive Surfaces | HTML
The basic function of the electrically conductive surface of electrical contacts is electrical conduction. The electrical conductivity of contact materials can be largely reduced by corrosion and in order to avoid corrosion, protective coatings must be used. Another phenomenon that leads to increasing contact resistance is fretting corrosion. Fretting corrosion is the degradation mechanism of surface material, which causes increasing contact resistance. Fretting corrosion occurs when there is a relative movement between electrical contacts with surfaces of ignoble metal. Avoiding fretting corrosion is therefore extremely challenging in electronic devices with pluggable electrical connections. Gold is one of the most commonly used noble plating materials for high performance electrical contacts because of its high corrosion resistance and its good and stable electrical behavior. The authors have investigated different ways to minimize the consumption of gold for electrical contacts and to improve the

Lead-tin alloy pipes in historic organs frequently suffer from damaging atmospheric corrosion. Organic acids emitted from the wood of organ cases had been established previously as the cause of deterioration in pure lead pipes. In the present study, lead-tin alloy samples containing 3.4 and 15 atom % tin were subjected to laboratory exposure experiments under atmospheres of 1100 ppb acetic acid, 350 ppm CO 2 , and 60 or 95% relative humidity (RH). Wet and dry corrosion mass gains were monitored, and corrosion product compositions and morphologies were characterized by grazing incidence angle X-ray diffraction and scanning electron microscopy. Cross sections were cut through corrosion sites using a focused ion beam milling method, and elemental information was obtained using wavelength dispersive and energy dispersive X-ray analyses. The corrosion products and morphologies observed in the alloys are the same as those reported for pure lead, but the corrosion susceptibilities of the alloys show a much

Experiment 11: Corrosion | iMechanica
Corrosion can be defined as the degradation of a material when it comes in contact with the environment. The dissolving of a material by a corrosive liquid is called chemical corrosion. The material continues to dissolve until either it is consumed or the liquid is saturated. A simple example is salt dissolving in water. The removing of metal atoms from a solid material as the result of an electric circuit is called electrochemical corrosion. In this form of corrosion, metal atoms lose electrons and become ions thus forming a byproduct. Electrochemical corrosion occurs most frequently in aqueous mediums, in which ions are present in water or moist air. In this process, an electric circuit is created and the system is called an electrochemical cell. Corrosion of a steel pipe or a steel automobile panel, creating holes in the steel and rust as the byproduct, are examples of this reaction..

Corrosion is electric
The corrosion process (anodic reaction) of the metal dissolving as ions generates some electrons that are consumed by a secondary process (cathodic reaction). These two processes have to balance their charges. The sites hosting these two processes can be located close to each other on the metals surface, or far apart depending on the circumstances. This simple observation has a major impact in many aspects of corrosion prevention and control, for designing new corrosion monitoring techniques to avoiding the most insidious or localized forms of corrosion.. One simple way to illustrate the two processes in a corrosion reaction is to use an external power source as illustrated in the corrosion current experiment. ...

The oxidation of water to form oxygen gas provides charge balance for the cathodic deposition of metals, such as zinc, in the electrorefining industry. This is a corrosive, four-electron electrochemical reaction that causes deterioration of lead-silver alloy anodes employed in these processes. A sacrificial manganese oxide layer on the anode surface, formed in-situ from manganese sulfate, is used in industry to reduce the corrosion rate of these anodes by preferentially enabling water oxidation rather than lead dissolution. Still, it is poorly understood how the activity of manganese oxide as a water oxidation catalyst relates to its anticorrosive properties. Here, we show how the presence of water oxidation catalysts both formed in-situ (including the industry standard manganese oxide) and heterogenized prior to electrolysis on lead anodes affect the corrosion potential of these anodes. We find that corrosion potential under dynamic polarization conditions is the parameter most affected by the coatings

BACKGROUND: The diagnosis of periprosthetic joint infection (PJI) in patients with failed metal-on-metal (MoM) bearings and corrosion reactions in hip arthroplasties can be particularly difficult, because the clinical presentation of adverse local tissue reactions may mimic that of PJI, because it can also occur concurrently with PJI, and because common laboratory tests used to diagnose PJI may be elevated in patients with MoM THAs.. QUESTIONS/PURPOSES: We sought to determine the test properties of the serum erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), synovial fluid white blood cell (WBC) count, and synovial fluid differential (percent polymorphonuclear cells [PMNs]) in diagnosing PJI in either MoM hips undergoing revision for a variety of indications or in non-MoM hips undergoing revision for either corrosion reaction or full-thickness wear. Additionally, we sought to describe how MoM bearings, metal debris, and corrosion reactions can confound the analysis of the synovial ...

Building Product: Surface-Applied Corrosion Inhibitor - Mapeshield™ CI 100 [102ada0] | ARCATBuilding Product: Surface-Applied Corrosion Inhibitor - Mapeshield™ CI 100 [102ada0] | ARCAT
Mapeshield CI 100 is a surface-applied corrosion inhibitor designed to penetrate concrete structures and protect embedded steel reinforcement. It forms a protective layer on the surface of the steel reinforcing bar to inhibit corrosion caused by carbonation, the presence of chlorides and other contaminants in the concrete (such as deposits from acid rain and industrial pollution), and helps to prevent additional cracking and spalling in the future. Mapeshield CI 100 can be applied by spray, brush or roller. By diffusing into the hardened pore structure of concrete to the steel reinforcing bars, Mapeshield CI 100 delays the corrosion process and reduces overall corrosion activity. ARCAT provides architectural information on building materials, manufacturers, specifications, BIM families and CAD details.

To investigate the causes of the destruction of the samples, the surface of samples was studied by scanning electron microscopy (SEM).

Spectrophotometric and conductometric titration methods were also utilized to investigate the possibilities of chemical adsorption between the steel surface and the compounds under consideration. The results showed that the studied compounds inhibit the corrosion of steel in acidic solution at different temperatures. The adsorption followed the Langmuir isotherm. The thermodynamic and the activation parameters were also determined and discussed.

CORROSION INHIBITORS FOR OILFIELD APPLICATIONS - Patent applicationCORROSION INHIBITORS FOR OILFIELD APPLICATIONS - Patent application
0003]It is well known that steel surfaces will corrode in the presence of the acid environments described. While the rate at which corrosion will occur depends on a number of factors, such as the steel alloy itself, the strength and type of corrosive components in the environment, the temperature of the environment, the length of contact, etc., some sort of corrosion invariably occurs. Alloy technology has provided materials to withstand the incidental contact of steel with corrosive components such as CO2 and/or H2S, but the corrosion problem is particularly aggravated when there is no choice but to contact steel with these components, as in the case of hydrocarbon exploration, recovery and refining--such as the oil and gas industry and in chemical processing and the like, where these components are inevitably present. In instances where the liquid is not required to remain pure and where the contact is inevitable, attention has turned toward providing corrosion inhibitors in the liquid medium ...

This study permitted to follow the evolution of the inhibitory effect of some azoles, on Cu-30Ni alloy corrosion in 3%NaCl polluted by ammonia and indicate that the tested inhibitors act as a good mixed-type inhibitor retarding the anodic and cathodic reactions. An increase of the inhibitors concentration leads to a decrease of corrosion rate and inhibition efficiency increase.

Microstructure Influence on the Corrosion of Permanent Mould Cast Magnesium Alloy AJ62 in Engine CoolantMicrostructure Influence on the Corrosion of Permanent Mould Cast Magnesium Alloy AJ62 in Engine Coolant
Powertrain applications of alloy AJ62 arose from its comparative resistance to high temperature deformation among magnesium alloys. In this research, AJ62 permanent-mould cast in different section thicknesses was subjected to immersion corrosion in commercially-available engine coolant. The objective was to determine corrosion behaviour variation among casting thicknesses. Corrosion product accumulation suggests passive film formation, and unlike in other media, the film exhibits certain stability. Extreme thicknesses were used to generate polarization curves for their respective microstructures in engine coolant. Variation with casting section thickness was observed in the curves. These preliminary results indicate coarsened microstructures reduce corrosion resistance of the permanent mold cast AJ62 alloy ...

Long-Cell Action Corrosion: A Basic Mechanism Hidden Behind Components Degradation Issues in Nuclear Power Plants | Volume 1:...Long-Cell Action Corrosion: A Basic Mechanism Hidden Behind Components Degradation Issues in Nuclear Power Plants | Volume 1:...
In spite of industries effort over the last 40 years, corrosion-related issues continue to be one of the largest unresolved problems for nuclear power plants worldwide. There are several types of strange corrosion phenomena from the point of view of our current understanding of corrosion science established in other fields. Some of these are IGSCC, PWSCC, AOA, and FAC (Erosion-Corrosion). Through studying and coping with diverse corrosion phenomena, the author believes that they share a common basis with respect to the assumed corrosion mechanism (e.g., local cell action hypothesis). In general, local cell action is rarely severe since it produces a fairly uniform corrosion. The long cell action that transports electrons through structures far beyond the region of local cell corrosion activities has been identified as a basic mechanism in soil corrosion. If this mechanism is assumed in nuclear power plants, the structure becomes anodic in the area where the potential is less positive and ...

Corrosion and hydrate formation in natural gas pipelinesCorrosion and hydrate formation in natural gas pipelines
Gas industry annually invests millions of dollars on corrosion inhibitors in order to minimize corrosion implications on flow assurance; however, attention has never been focused on possibilities of these chemicals to promote hydrate formation along deepwater pipelines, which would equally result in another flow assurance problem of high magnitude. This study investigated the possibilities of corrosion inhibitors to aid the formation of gas hydrate along offshore (or underwater) pipeline systems; developed a predictive model on corrosion rate for natural gas pipelines with gas hydrates as the corroding agent and finally investigated the ability of pure N2 and H2 gases to inhibit the formation of gas hydrates.All experiments in this thesis were conducted by forming various water-gas systems in a cylindrical cryogenic sapphire cell. The first investigative work on hydrate-corrosion relationship was conducted by allowing contacts between an industrial grade natural gas (with 20% CO2 content) and ...

OPUS 4 | 4 Material und Umwelt
Different environmental samples reveal that methanogenic Archaea are part of a multi-species biofilm on corroding metallic structures. Studies on microbial influenced corrosion (MIC) focus mainly on sulphate reducing Bacteria (SRB), leading to the assumption that they are exclusively responsible for metal corrosion. In fact, methanogenic Archaea are known to be involved in metal corrosion as well (e.g. Methanococcus maripaludis DSM 2067). In some cases SRB and methanogenic Archaea have comparable high corrosion rates. However, the underlying mechanisms causing corrosion are still unknown. The goal of this study is to develop suitable methods for analyzing two environmental isolates (M. maripaludis DSM 2067, M. maripaludis KA1) and two human-related isolates (Methanobrevibacter oralis and Methanobrevibacter smithii) for their ability to deteriorate/transform metals, which are relevant for technical and clinical applications. Moreover, the studies will provide essential information on the ...

Erosion/corrosion of machinable Tungsten in water. - Digital Library
It was recently discovered that significant erosion/corrosion occurs with machinable tungsten when exposed to water, particularly when the water has dissolved oxygen present. The problem was first discovered about 1 1/2 years ago when extensive corrosion was found inside the cooling channels of the L5-80 white-beam slits located in sector 3-ID-A. Figure 1 and Figure 2 show cut-away sections of the tungsten slit; the water passages are severely corroded from the cooling water used to cool the slit. The problem was brought to the attention of the worlds two largest manufacturers of machinable tungsten, Mi-Tech Metals from Indianapolis, IN and Kulite Tungsten Corp. from East Rutherford, NJ. Neither company had any experience with this problem and were unaware that water could cause such significant corrosion, apparently the APS was the first customer to ever use the material in this fashion.

One of the primary functions of modern heavy duty diesel (HDD) lubricants is to protect the engine against corrosion, which is typically accomplished by additives providing alkaline material, commonly represented as total base number (TBN). The majority of the TBN in HDD lubricants comes from ash-containing over-based detergents, with various metallic base and soap chemistries. In this publication, we discuss several overbased detergents and their efficacy in acid neutralization, as well as the resulting impact on corrosion protection. The performance differences are compared in a number of stationary API CJ-4 and CK-4 HDD engine screener tests. Furthermore, these results are confirmed with field trial data, including a comparison of CJ-4 oils with the upcoming API FA-4/CK-4 oils. The selection of overbased detergent type provides varying levels of acid neutralization and corrosion protection. Within a constrained sulfated-ash environment, TBN can be maximized via the use of magnesium-based ...

The inhibition of the corrosion of the mild steel in 1M HCl by new bipyrazolic compounds has been studied by weight loss, electrochemical polarisation and electrochemical impedance spectroscopy (EIS) measurements. Results obtained reveal that these compounds are very good inhibitors. The inhibition efficiency increases with the increase of inhibitor concentration and reached 94 at 10-3M for the bipyrazoles studied. Potentiodynamic polarisation studies clearly reveal that the presence of the bipyrazoles does not change the mechanism of the hydrogen evolution reaction and they act essentially as cathodic inhibitors. The effect of temperature on the corrosion behaviour of mild steel in 1M HCl without and with the bipyrazoles at 10-3M was studied in the temperature range from 298° to 343°K. EIS measurements show the increase of the transfer resistance with the inhibitor concentration.. ...

The inhibition effect of sodium diethyldithiocarbamate (SDDTC) and sodium acetate (NaAc) as green ecofriendly corrosion inhibitor for magnesium (Mg) alloy AZ31B (3wt% aluminum and 1wt% zinc) in 3.5 wt.% NaCl solution was investigated by electrochemical measurements, weight loss measurements, scanning electron microscopy (SEM) and fourier transformation infrared spectroscopy (FTIR). Results reveal that the combined addition of SDDTC or NaAc can synergistically inhibit the corrosion of Mg alloy AZ31B and an optimal inhibition efficiency in terms of corrosion of AZ31B substrate was yielded in 3.5 wt% NaCl electrolyte containing 0.3 × 10-3 mol L-1 SDDTC and 0.15 mol L-1 NaAc. Surface analysis results suggest the corrosion inhibition ability of SDDTC and NaAc in the naturally corrosion system could be attributed to the formation of a compact protective film. The corrosion inhibition efficiency of the combined addition was predominantly because of SDDTC would chelate with Mg via their N atoms to form ...

A 3-D continuum mixture model describing the corrosion of concrete with sulfuric acid is built. Essentially, the chemical reaction transforms slaked lime (calcium hydroxide) and sulfuric acid into gypsum releasing water. The model incorporates the evolution of chemical reaction, diffusion of species within the porous material and mechanical deformations. This model is applied to a 1-D problem of a plate-layer between concrete and sewer air. The influx of slaked lime from the concrete and sulfuric acid from the sewer air sustains a gypsum creating chemical reaction (sulfatation or sulfate attack). The combination of the influx of matter and the chemical reaction causes a net growth in the thickness of the gypsum layer on top of the concrete base. The model allows for the determination of the plate layer thickness h=h(t) as function of time, which indicates both the amount of gypsum being created due to concrete corrosion and the amount of slaked lime and sulfuric acid in the material.

Demonstration of Zirconium Oxide Pretreatment to Prevent CorrosionDemonstration of Zirconium Oxide Pretreatment to Prevent Corrosion
The current phosphate-based pretreatment process used for U.S. Department of Defense weapons systems and platforms to prevent corrosion poses multiple health, safety, and compliance hazards. It utilizes zinc phosphate, which raises environmental concerns with hazardous air pollutants ( HAP) and heavy metals such as Cr VI or Ni. In addition, this particular pretreatment does not provide adequate corrosion protection due to the porous nature of the coating. Although the surface morphology allows for better absorption of lubricants, it also increases the attack of corrosives to base metal substrates. ESTCP project WP-201318, led by Fred Lafferman of U.S. Army Research Laboratory (ARL) is demonstrating an innovative and cost-effective replacement technology utilizing zirconium oxide as a pretreatment.. Zirconium-based metal pretreatment technology is a better alternative to multiple conventional technologies such as zinc phosphate, chromate-containing etch primers, and chromate conversion coatings. ...

Confocal Microscopy of Corrosion CastsConfocal Microscopy of Corrosion Casts
The casting polymer from which a corrosion cast is made has fluorescent properties, that is, when excited by a light beam of a specific wavelength, it emits light at a longer wavelength. A corrosion cast, therefore is an ideal specimen for examination by confocal microsopy. In laser confocal microscopy (LSM) , a laser beam excites fluorescent substances by scanning across a specimen in a square pattern called a raster. The resulting fluorescent signal is collected from only a single focal plane. This results in sharp, high contrast fluorescent images due to elimination of fluorescence above and below the focal plane. Successive optical sections can be acquired by moving the focus in increments through the specimen, a process known as optical sectioning. Numerous optical sections through through the specimen are known as a z-stack and results in a three-dimensional data set which whichiis stored digitally as voxels, a cubic picture units analagous to pixels. The casting polymer emits a strong ...

AU - Amemiya, T.. PY - 2001/10/1. Y1 - 2001/10/1. N2 - Purpose. To demonstrate specific hypercholesterolemic changes in the retinal vascular architecture. Methods. Corrosion casts of 12- to 18-month-old rats with inherited hypercholesterolemia (RICO) and of control Wistar Kyoto (WKy) rats were examined with a scanning electron microscope (SEM). The diameters of the retinal arteries, veins and capillaries were measured in photographs with a caliber micrometer. The capillary branches were counted in the micrographs with the use of Adobe Photoshop. The retinal capillaries were examined by transmission electron microscopy (TEM). Results. SEM examination of the vascular casts of 15-month-old RICO rats showed slight tortuosity of large vessels at the posterior pole of the retina. The precapillary arterioles branching ...

  • Toronto's Corrosion Control Plan was adopted by City Council, and is supported and endorsed by Toronto Public Health as a safe way to reduce the amount of lead in tap water and the associated health risks. (toronto.ca)
  • The City is continuously evaluating the effectiveness of corrosion control and is adjusting the phosphate dose accordingly. (toronto.ca)
  • For this reason, customers already adding phosphate to precipitate calcium may benefit from the implementation of Corrosion Control. (toronto.ca)
  • The aim of the course is to introduce the complex world of corrosion and corrosion control. (coursera.org)
  • The course mirrors elements of the Corrosion Control Engineering teaching programme at The University of Manchester for final-year undergraduates and masters-level postgraduates and is used as a supplementary learning resource by our students. (coursera.org)
  • The effects of corrosion and it's control in confined spaces can cause traumatic injury and death to workers who must enter confined spaces. (cdc.gov)
  • Confined space fatality surveillance in Alaska and other locations has identified risk factors associated with corrosion and corrosion control activities. (cdc.gov)
Water7
  • On comparing together the loss of weight f metal in the fresh water, sea water, and jrinej it will be observed, that in sea water jhe corrosion is about one-third more than in fresh water? (scientificamerican.com)
  • Although the experiments on the corrosion of iron were continued for eighty days, the difference be-;ween the action of common water and brine nay be made apparent in one day. (scientificamerican.com)
  • White mounting paste for screws and bolts with excellent corrosion protection and water stability. (castrol.com)
