An inventive workpiece features on at least parts of its surface a wear resistant hard coating comprising the following composition AlCrXSiBZ, where x is at least one element from Nb, Mo, W or Ta; Z is one element or compound from N, C, CN, NO, CO, CNO; and 0.2&#x3c;=a&#x3c;=0.5; 0.01&#x3c;=b&#x3c;=0.2; 0&#x3c;=c&#x3c;=0.1; 0&#x3c;=d&#x3c;=0.1. Further a PVD process for depositing such a wear resistant coating is disclosed whereby at least one workpiece is installed in a vacuum coating system and said system is operated in a low pressure argon atmosphere utilizing at least two metal or metal alloy targets with at least temporarily addition of a reactive gas.

High oxidation resistant hard coating for cutting tools

A work piece or structural component is coated with a system of film layers at least one of which is composed of (AlCr)X, where X=N, C, B, CN, BN, CBN, NO, CO, BO, CNO, BNO or CBNO and 0.2&#x2266;y&#x3c;0.7, with the composition within said film being either essentially constant or varying over the thickness of the film continually or in steps, as well as a process for producing it.
