Abstract
A PVD process for manufacturing a coating (16, 18, 20, 22, 23) on articles (12), in particular on articles which have a relatively low temperature resistance such as articles made of brass, zinc and plastic, including such with an electroplated coating, wherein a plurality of layers (16, 18, 20, 22) are built up by arc discharge vaporization to manufacture a colored coating insensitive to fingerprints and are selected in order to achieve a color by this kind of coating alone which corresponds as far as possible to the desired end color; and wherein a hard material cover layer (23) is applied to the layer structure by means of cathode or magnetron sputtering or by the simultaneous use of arc discharge vaporization and cathode or magnetron sputtering, said cover layer generating the final color and being limited to the smallest possible layer thickness, preferably to under 500 nm.
