ABSTRACT:
Cobalt cemented carbide cutting inserts are prepared for coating with a hard, wear-resistant coating by providing a cobalt enriched zone on a surface to be coated. Cobalt enrichment is effectuated by means of nitrogen gas contact with the carbide followed by a period of vacuum sintering during its sintering process of manufacture.
