Summary:PROBLEM TO BE SOLVED: To provide a PVD or PECVD coated cutting tool having improved adhesive property and wear resistance. SOLUTION: This cutting tool includes a substrate of cemented carbide, etc. applied with a thin, adhesive, hard and wear resistant film on at least a functional part of a surface. The film includes laminated multilayers of alternately arranged PVD or PECVD metal oxide layers. The film has entire thickness of 0.2 to 20 μm of metal oxide + metal oxide nanocomposite material layers, etc, and a composition gradient. COPYRIGHT: (C)2008,JPO&INPIT
