Background: The aim of this study was to evaluate and compare the changes in the mechanical properties and surface morphology of different orthodontic wires after immersion in three mouthwash solutions. Materials and Methods: In this in vitro study, five specimens of each of 0.016 inch nickel titanium (NiTi), coated NiTi, and stainless steel orthodontic wires were selected. The specimens were immersed in 0.05 sodium fluoride (NaF), 0.2 chlorhexidine, Zataria multiflora extract, and distilled water (control) for 1.5 h at 37°C. After immersion, loading and unloading forces at 0.5 mm intervals and the elastic modulus (E) of the wires were measured using a three-point bending test. Surface changes were observed with a scanning electron microscope (SEM). Two-way analysis of variance and Bonferroni tests were used to compare the properties of the wires. The level of significance was set at 0.05. Results: Statistically significant changes in loading and unloading forces and E of the orthodontic wires ...
The mechanical properties and corrosion resistance changes of AlSi10Mg(Cu) alloy under different isothermal exposure conditions have been investigated by tensile experiments and electrochemical testing. The results show that isothermal exposure has a significant influence on the mechanical properties and corrosion resistance. Tensile strength is more sensitive to the higher exposure temperature, while the corrosion resistance is greater affected by the lower exposure temperature and shorter time. Microstructure evolution of AlSi10Mg(Cu) alloy related to different isothermal exposure condition has also been studied by using transmission electron microscopy (TEM). The results indicate that the isothermal exposure changed the type and density of nanoscale precipitates in the alloy, which in turn induced the change of performance of the alloy.
TY - JOUR. T1 - Increased corrosion resistance of stent materials by converting current surface film of polycrystalline oxide into amorphous oxide. AU - Shih, Chun Che. AU - Lin, Shing Jong. AU - Chung, Kwok Hung. AU - Chen, Yuh Lien. AU - Su, Yea Yang. PY - 2000/1/1. Y1 - 2000/1/1. N2 - Current efforts of new stent technology have been aimed largely at the improvement of intravascular stent biocompatibility. Among the chemical characteristics of metallic stents, surface oxide corrosion properties are paramount. Using our unique technique, the currently marketed 316 L stainless steel and nitinol stent wires covered with polycrystalline oxide were chemically etched and then passivated to form amorphous oxide. Excellent metallicstent corrosion resistance with an amorphous oxide surface was demonstrated in our previous in vitro study. For in viva validation, we compared the corrosion behavior of different oxide surfaces on various forms of test wires in the abdominal aorta of mongrel dogs using ... offers 951 niti alloy rods bars products.

All silver objects should be kept clean and free of dust and surface grime.. The formation of tarnish inside display cases can be minimized by using desiccated silica gel to keep the relative humidity (RH) low, and activated charcoal or a suitable commercial product to remove tarnishing gases.. Tarnish need not be removed before storage. It is better to remove tarnish from silver only when necessary, e.g. for display purposes. Whether or not silver needs to be stored with a bright and shiny finish will depend on a variety of factors that must be considered for each collection.. Tarnishing can be minimized during storage by placing individual silver objects inside polyethylene bags and then sealing the bags using tape, heat sealing, or a self-sealing bag. It is always good practice to wrap or support each piece of silver with acid-free tissue paper (non-buffered or unbuffered which is sulphur-free and of archival quality) to buffer changes in RH and to prevent transfer of harmful materials ...

One of the most common applications for electropolishing is to enhance corrosion resistance on a wide variety of metal alloys, specifically stainless steel. Electropolishing is quickly becoming a replacement process for a long established treatment: Passivation. Passivation is a chemical process that has been used for years to help restore contaminated stainless steel to original corrosion specifications.

This is a kidney shaped stainless steel tray with a stainless steel dental mirror, tweezers and a dental explorer. The tray is well sized to accommodate the instruments in the kit and an other which you may have collected over time. Like the shape of the instrument handles - they are square rather than the usual round shape which make them easier to hold and handle. Cons: the edges of the tray are not well tapered and the user need to exercise special care since there a risk of being cut if the tray is held by the edge. Would have preferred a rectangular tray with a well tapered edge. Read more ...

347 Stainless Steel UNS S34700 | UlbrichCold Forming. Type 347 can be readily formed and drawn. Like most other austenitic stainless steels, type 347 work hardens and may require annealing after severe forming. Heat Treatment. Type 347 is non hardenable by heat treatment. It can only be hardened by cold working. Welding. Type 34 7 is weldable by common fusion and resistance methods.
Gigi molar pertama permanen mempunyai predisposisi paling tinggi untuk terjadinya karies karena gigi ini mempunyai pit dan fisur yang dalam sehingga memudahkan retensi plak. Restorasi amalgam dan resin komposit tidak diindikasikan untuk merestorasi gigi molar pertama permanen muda yang terkena karies luas karena dukungan retensi yang tidak baik. Sedangkan restorasi rigid seperti onlay, mahkota penuh dan mahkota pasak juga tidak diindikasikan karena morfologi pulpa dan pertumbuhan erupsi gigi yang belum sempuma serta sikap anak yang kurang mendukung sehingga tidak memungkinkan untuk pemasangan restorasi tersebut. Mahkota stainless steel merupakan pilihan yang tepat untuk merestorasi gigi molar pertama permanen muda dengan karies luas karena dapat menutupi seluruh permukaan gigi dan preparasinya tidak membahayakan pulpa. Mahkota stainless steel pada gigi molar pertama pennanen muda merupakan perawatan pendahuluan yaitu sebagai rnahkota sementara karena pada akhirnya diganti dengan mahkota penuh ...
