As one of the two types of corrosion, generalized corrosion processes that take place on metals are usually correlated with uniform metallic reactivity, with low or controlled reaction rates allowing life prediction of materials.5个回答 因为这两个类型的腐蚀之一,是发生在广义的金属腐蚀过程通常关联与均...
A chemical-mechanical polishing ("CMP") composition (P) comprising\n(A) inorganic particles, organic particles, or a mixture or composite thereof,\n(B) at least one type of N-heterocyclic compound as corrosion inhibitor,\n(C) at least one type of a further corrosion inhibitor selected from...
1. A chemical-mechanical polishing (CMP) composition, comprising: inorganic particles, organic particles, or a mixture or composite thereof, an N-heterocyclic compound as corrosion inhibitor, a further corrosion inhibitor which is a salt, or adduct of an amine and a carboxylic acid comprising an ...

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...
Furthermore, the partial pressures of certain gases in a contacting atmosphere can be highly significant and at elevated temperatures can contribute to serious corrosion of metals (e.g. O2, S2 (Chapter 12)). Again, the pressure variable must be taken into account....
aThe purpose of the present study is to clarify the corrosion evolution of as-cast AZ91 alloy with addition of rare earth Y in 3.5 wt.% NaCl solution by investigating the surface structure of oxide films on the AZ91 alloys by X-ray photoelectron spectroscopy (XPS) analysis and corrosion behav...
