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.

The present invention provides an optimized hard coating and a workpiece, especially a cutting tool coated with a hard coating to increase tooling performance with difficult to machine materials such as high speed steels, titanium alloys, nickel alloys, austenitic steels and especially hard materials like hardened tool steel having a hardness of higher 50, preferably of higher 55 HRC. This is achieved by a workpiece coated with a wear resistant multilayered comprising at least a first supporting layer and a second nanocrystalline layer, whereas the first layer comprises a coating material of the following composition (TiAl)NCOwith 0.4&#x3c;a&#x3c;0.6, and 0&#x2266;x and y&#x3c;0.3, or (AlCr)NCOwith 0.5&#x3c;b&#x3c;0.7, and 0&#x2266;x and y&#x3c;0.3. The second layer comprises a coating material of the following composition (AlCrSiM)NCOwhereas M stands for at least one element of the transition metals of group 4, 5, 6 of the periodic system except Chromium and 0.2&#x3c;c&#x2266;0.35, 0&#x3c;d&#x2266;0.20, 0&#x3c;e&#x2266;0.04.

Wear resistant hard coating for a workpiece and method for producing the same

A vacuum process system for surface-treating work pieces uses an arc evaporation source. The system has a first electrode connected to a DC power source and a second electrode, disposed separately from the arc evaporation source. The two electrodes are operated while being connected to a single pulsed power supply.
