<p>An inventive workpiece features on at least parts of its surface a wear resistant hard coating comprising the following composition Al1-a-b-c-d CraXb SicBd Z, 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 <=a <= 0.5; 0.01 <= b <= 0.2; 0 <= c <= 0.1 ; 0 <= d <= 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.</p> |
