De-alloying, or selective leaching, is the selective corrosion of a specific element in analloy. The most common type of de-alloying is de-zincification of unstabilizedbrass. The result of corrosion in such cases is a deteriorated and porouscopper. Fretting corrosion: Fretting corrosion occurs a...
Ethanolamine is less corrosive to Q235A steel than ammonia in ACQ derived from cupric hydroxide,while other ingredients are the same;Epoxy resin coating could be used for protecting red brass,Q235A steel and zinc hot-dipped galvanized mild steel from corrosion.supports all the CNKI file formats;...
Stress corrosion cracking results from the conjoint action of three components: (1) a susceptible material; (2) a specific chemicalspecies(environment) and (3) tensile stress. For example, copper and its alloys are susceptible to ammonia compounds, mild steels are susceptible to alkalis and ...
The influence of deformation temperature, strain rate and alloying elements such as chromium, nickel, copper, on corrosion resistance of a 304 stainless steel after plastic deformation was investigated. The techniques employed were tensile test at room and elevated temperature, deep drawing tests at va...
Over the years, a number of testing protocols have been developed, including cyclic corrosion testing, salt spray testing, humidity testing, Kesternich chamber testing and specialized tests designed to simulate the specific conditions of a given coating (e.g. chrome, nickel, copper, etc.). ...
Copper pipesare a type of tubing that is frequently used in plumbing. They are made from a ductile metal that is resistant to corrosion, making them an ideal choice for carrying potable water. Copper pipes can handle high pressure, are very durable, and come in 4 types as shown in the ...
There are two types of high-copper dental amalgams produced in Iran; Cinalloy (lathe-cut particles) and Cinalux (spherical particles). Tarnish is one of the disadvantages of dental amalgam, which precedes corrosion, and in fact it means real destruction of restorative materials. The purpose of...
