    摘要: A multilayer hard coating for tools for machining applications with a multilayer structure for improving the wear resistance of workpieces includes at least one (AlyCr1-y)X layer (0.2≦y≦0.7), wherein X is one of the following elements N, C, B, CN, BN, CBN, NO, CO, BO, CNO, BNO, CBNO, but preferably N or CN, and/or a (TizSi1-z) layer (0.99≧z≧0.7). The hard coating also includes at least one layer stack with one (AlCrTiSi) X mixed layer, followed by another (TizSi1-z)X layer, followed by another (AlCrTiSi) X mixed layer, followed by another (AlyCr1-y)X layer.
