Abstract:
A hard film for coating a surface of a base material, the hard film includes a layer A, a layer B, and a nanolayer-alternating layer. The layer A is an AlTiCr nitride of (AlaTibCrcαd)N, where α is one or more elements selected from C, B, Si, V, Y, Zr, Nb, Mo, Hf, Ta, and W. The layer B is an AlTiCr nitride or AlTiCr carbonitride of (AleTifCrgβh)CxN1-X, where β is one or more elements selected from B, Si, V, Y, Zr, Nb, Mo, Hf, Ta, and W. The nanolayer-alternating layer is formed by alternately laminating a nanolayer A or a nanolayer B having the same composition as the layer A or B. And, the layer C is an AlCr(SiC) nitride or AlCr(SiC) carbonitride of [AliCrj(SiC)kγl]CYN1-Y, where γ is one or more elements selected from B, Ti, V, Y, Zr, Nb, Mo, Hf, Ta, and W.
