摘要:
A hard multilayer coating that is to be disposed on a body, including: (a) a first coating layer disposed to be held in contact with the body, the first coating layer consisting of TiAlCrX1-aNa (wherein “X” represents carbon or oxygen, and “a” represents a mixed crystal ratio satisfying 0.5≦a≦1); (b) a second coating layer disposed on the first coating layer, the second coating layer being provided by a mixture layer consisting of TiAlCrX1-bNb (wherein “b” represents a mixed crystal ratio satisfying 0.5≦b≦1) and TiAl(SiC)X1-cNc (wherein “c” represents a mixed crystal ratio satisfying 0.5≦c≦1), or provided by a multilayer including a first sublayer consisting of the TiAlCrX1-bNb and a second sublayer consisting of the TiAl(SiC)X1-cNc, which are alternately superposed on each other; and (c) a third coating layer disposed on the second coating layer and constituting an outermost layer of the hard multilayer coating, the third coating layer consisting of TiAl(SiC)X1-dNd (wherein “d” represents a mixed crystal ratio satisfying 0.5≦d≦1).
