Production of carbon coating film

Abstract

Abstract PURPOSE:A support base is coated with a specific aromatic polymer compound, and carbon coating film is deposited on the support by decomposing the coating with heat under vacuum where by uniform carbon coating films with high electroconductivity and high hardness is formed at a relative temperature. CONSTITUTION:An aromatic high polymer which has large amounts of components to be gasified on pyrolysis such as polyparaphenylene oxide, polyparaphenylene sulfide, polycarbonate or phenolic resin is used to coat the support base such as a plate of carbon, silicon, alumina, silicon carbide or boron nitride in the form of a solution and dried. A film of the high polymer may be held between the support bases. Then, the coated bases are heated in an inert atmosphere or under vacuum over 700 deg.C to deposit the carbon formed on the base.
