Ceramic Coating - an overview | ScienceDirect Topics
Ceramic coatings  include a large group of subspecies, such as chemical vapor deposited silicon carbide, plasma spray deposited aluminum oxide, and plasma spray deposited chromium oxide. In order to achieve the required quality, efficient machining of these ceramic coatings is still under development.
Silicones - Essential Chemical Industry
Silicon is first converted into chlorosilanes, e.g. RSiCl 3, R 2 SiCl 2 and R 3 SiCl, where R is an organic group. When chloromethane is passed through heated silicon at about 550 K under slight pressure and in the presence of a copper alyst (often copper itself but other copper-containing materials can be used, for example, brass or copper(II) chloride) a volatile mixture of chlorosilanes

Carbide Types in Knife Steels - Knife Steel Nerds
15/7/2019· Silicon carbide has a similar hardness to those hard carbides but is not clearly harder, and in general silicon carbide is not as good at cutting steel as aluminum oxide. CBN and diamond are significantly harder than any of the carbides so they are generally better at least in terms of grinding and polishing high wear resistance steels with hard carbides.
