Title:
COATED MEMBER
Document Type and Number:
WIPO Patent Application WO/2010/007958
Kind Code:
A1
Abstract:
A coated member for cutting tools which renders a long life possible under severe cutting conditions as in high-speed processing, high-feed-rate processing, cutting of works having enhanced hardness, and cutting of works difficult to cut. The coated member comprises a base having a surface coated with one or more coating films. At least one of the coating films is a hard film of a cubic metallic compound comprising at least one metallic element (M) selected from Al, Si, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W and at least one element (X) selected from C, N, and O. In the pole figure for the (111) plane of the hard film, the X-ray intensity distribution in the α axis has a maximum intensity in the α-angle range of 75-90°. In the pole figure for the (220) plane of the hard film, the X-ray intensity distribution in the α axis has a maximum intensity in the α-angle range of 75-90°.
