Title:
HARD COATING COVERED TOOL
Document Type and Number:
Japanese Patent JP3589396
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hard coating covered tool capable of dealing with dry cutting work and high speed cutting work by increasing oxidation resistance without sacrificing wear resistance and adhesion of a conventional TiAlN coating.
SOLUTION: One or more layers (a) and one or more layers (b) are layed alternately, respectively. The layer (a) is composed of metal component: 10-60 atomic % of one or two kinds or more of Si, Cr, Nb and the rest: any one of nitride, carbonitride, nitroxide and carbonitroxide composed of Ti, and has a thickness of 0.1 μm-3 μm. The layer (b) is composed of metal component: 40-75 atomic % of Al and the rest: any one of nitride, carbonitride, nitroxide and carbonitroxide composed of Ti. A layer (c) is laid just one just on a surface of a base material while the layer (b) is laid just on the layer (c). The layer (c) is mainly composed of Ti as its metal component and has a thickness of 0.1 μm-1 μm.
