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.

1-9. (canceled)
A process for forming a wear- and corrosion-resistant coating on a decorative hardware substrate comprising:
- a) forming a Ni dispersion coat which forms a surface with embedded, non-conducting particles;
- b) electrolytically forming a discontinuous Cr coat over the Ni dispersion coat with pores in the Cr coat corresponding to locations of the non-conducting particles embedded in the Ni dispersion coat;
- and
- c) forming a coat of a Group IV B oxide, nitride, or carbide over the Cr coat.
