摘要

The ion bombardment of Cr, etc. onto a surface of a WC-based cemented carbide substrate in a nitrogen-based gas forms a modified phase having a bcc structure on the substrate surface, and a hard coating containing at least Cr formed thereon has high adhesion to the substrate by the modified phase.
