Hard Amorphous Carbon PVD Coatings

Abstract

Amorphous diamond-like carbon (ADLC) coatings are deposited on cemented carbides, high speed steels (HSS) and other steels, using arc-ion plating. The paper describes both the problems and the potential of this process with its many influencing parameters. It also details a number of properties of hydrogen-free a-C films deposited at coating temperatures of 200 °C; as an example, a tribological application is described.
