Patent ID: 7537822

Claim:
A hard-coated member comprising a hard coating comprising a lowermost layer, an intermediate laminate and an uppermost layer on a substrate member, said intermediate laminate being constituted by alternately laminated layers A and layers B having different compositions, said layers A and said layers B being respectively made of at least one member selected from the group consisting of nitrides, borides, carbides and oxides of metal components having compositions represented by the formula of Al W Cr X Ti Y Si Z , wherein W, X, Y and Z respectively represent atomic % of Al, Cr, Ti and Si, W+X+Y +Z=100 and Z>0, and these combinations, said layers A meeting the condition of 70≦W+X<100, said layers B meeting the condition of 30≦Y<100, and said uppermost layer being made of at least one member selected from the group consisting of nitrides, carbides, sulfides and borides of Ti or Ti and Si and these combinations, and wherein each of said layers A has a thickness of 2-50 nm and each of said layers B has a thickness of 2-50 nm, respectively.
