Abstract
A carbon film is formed on a ceramic element, or a metal film is formed on the carbon film, and subsequently the ceramic element is bonded to another ceramic or metal element, thereby forming a composite article. The composite article has a high bonding strength and is hardly fractured at joint. Ceramic articles having a surface coating of a hard carbon film or a hard carbon film containing metal grains can also be formed by this process.
