Cannulated screws, along with guide wires, are typically used for surgical fracture treatment in cancellous bone. Breakage or bending deformation of the guide wire is a clinical concern. Mechanically superior guide wires made of Co-Cr alloys such as MP35N and L605 may reduce the occurrence of mechanical failures when used in combination with conventional (316L stainless steel) cannulated screws...

Corrosion of metal is a ubiquitous phenomenon that occurs in various paperwork. Atmospheric or uniform, galvanic, crevice, pitting, and microbial corrosion are maximum familiar styles corrosion. The consequences many varied the outcomes those at safe, dependable green operation gadget structures frequently extra serious than simple loss mass metal. screw ups types need for highly-priced replace...

We investigated film thickness effects of sulfuric acid anodized aluminum when galvanically coupled with carbon fiber reinforced plastic（CFRP）. The CFRP was electrically to alloys 1050, 5052, 6061, and 7075 in 3.5 wt.% NaCl solution at 35 ℃. Galvanic current passing from the 1050 6061 decreased as anodic oxide thickened. For galvanic between 5052 CFRP, elapsed time until corrosion density value...

The effect of microstructure on the stress corrosion behavior of Mg–Sn alloys was investigated using a bent-beam method. The effects of an Mg2Sn phase and Sn in the matrix on stress corrosion were investigated. Mg2Sn phase mainly formed at the grain boundary. The volume fraction of the Mg2Sn phase increased with increasing Sn content, and the morphology of Mg2Sn changed from spherical to a semi...

The aim of this investigation was to determine the influence of fluoride in certain mouthwashes on the risk of corrosion through galvanic coupling of orthodontic wires and brackets. Two titanium alloy wires, nickel-titanium (NiTi) and copper-nickel-titanium (CuNiTi), and the three most commonly used brackets, titanium (Ti), iron-chromium-nickel (FeCrNi) and cobalt-chromium (CoCr), were tested i...

Only a low southerly chop ruffled Georgia Strait that autumn afternoon as an aluminum gillnetter left the broad Fraser River delta and took up a course toward Active Pass. Apparently, by the time the skipper discovered she was filling from the lazarette, it was already too late for the pumps to catch up; so he radioed for help and got ready to let her go. We got there in time to see the Canadia...

Metal ceramic partial fixed dental prostheses have been commonly used for the replacement of missing teeth for many years. Because of an increase in the price of gold, base metal alloys have been the choice of alloy for the fabrication of metal ceramic restorations in many dental clinics. Some major disadvantages of base metals are their corrosion and the dark coloration they may cause at the c...

Chromium cast irons (CCI) comprise versatile materials that encompass a range of compositions and microstructures often chosen to promote good wear resistance. There are, however, issues arise when the iron is required operate in conditions where corrosion, as well as, factor. This scenario usually results adapting composition CCI order achieve higher chromium content metallic matrix and, there...
