ABSTRACT:
The subject of the invention is a layer system for the decorative coating of galvanizable work pieces. In order to have a layer system which meets strict requirements with regard to corrosion resistance and which, at the same time, has a high abrasion resistance and, in addition, provides a high degree of freedom with regard to decorative coloration, the invention proposes a layer system which is formed by galvanic deposition and comprises a base coat consisting of at least one bright layer and one discontinuous chrome layer as well as a cover coat of mechanically resistant materials deposited by the PVD process.
