Abstract:
A surface-coated titanium carbonitride-based cermet cutting tool is a surface-coated TiCN-based cermet cutting tool in which a Ti compound layer that is a hard coating layer is deposited as a first layer on the surface of a TiCN-based cermet body containing W and Mo, and a Mo-enriched layer having an average thickness of 0.5 to 10 nm is formed at an interface between a TiCN phase of the body and the hard coating layer.
