We commonly use coatings such as Teflon™, pyrolytic carbon or pyrolytic graphite, silicon carbide, and diamond or diamond-like coatings. Once the carbon graphite materials are molded, baking is necessary. Baking is an essential part of the process because, at this point, the powders are being held together by the binder, but the material does ...
