Layered film made of ultrafine particles and a hard composite material for tools possessing the film |
摘要 |
Ultrafine particle-layered film for coating cutting tools. The film has more than two layers of at least two compounds consisting mainly of carbide, nitride, carbonitride or oxide of at least one element selected from a group consisting of IVa group elements, Va group elements, VIa group elements, Al, Si and B, and that each layer is made of ultrafine particles. Ultrafine particle-layered film improves hardness, strength, wear-resistance and heat-resistance of the tools.
