ABSTRACT:
A coated carbide insert has a cobalt enriched zone at one decarburized surface, and a thin TiN transition layer over this surface. The cobalt enriched zone and the TiN layer cooperate to support additional thicker layers of hard wear resistant material such as TiC, TiN, and Al.sub.2 O.sub.3.
