摘要

A modification phase having a bcc structure is formed on the surface of a WC based cemented carbide base by subjecting the base surface to an ion bombardment treatment of Cr or the like in a gas that is mainly composed of nitrogen and a hard film containing at least Cr is formed on the modification phase. Consequently the base and the hard film have high adhesion to each other due to the modification phase.
