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.
Claims9
A layer system for the decorative coating of galvanizable work pieces, comprising a base coat consisting of at least one bright layer and of a discontinuous chrome layer, formed by a galvanizable deposition, as well as a cover coat consisting of mechanically resistant materials, deposited by means of the PVD process.
A layer system in accordance with one of the foregoing claims, characterized by the base coat between the bright layer and the discontinuous chrome layer showing a further nickel layer.
A layer system in accordance with one of the foregoing claims, characterized by the base coat in the direction of thickness showing a third nickel layer below the bright layer.
A layer system in accordance with one of the foregoing claims, characterized by the base coat showing a copper layer as the lowest layer in the direction of thickness.
A layer system in accordance with one of the foregoing claims, characterized by preferably elements of the IV complex being used as mechanically resistant materials, especially titanium, zirconium and hafnium, combinations thereof and/or their nitrides, oxides or carbides.
