Abstract
A diamond thin film coating method is provided that enables, with no need for an intermediate layer, the formation of a diamond thin film, which has conventionally been considered difficult because cobalt contained in a binding phase of a cemented carbide provides a catalysis for the formation of graphite. Cobalt in a binding phase () present in a surface of a cemented carbide substrate member comprised of a hard phase of a carbide () and a binding phase () containing cobalt, is silicidated into silicide (), and thereafter the diamond thin film is formed.
