Abstract

The invention relates to a composite material having a chromium-containing top layer, comprising an adhesion-promoting layer located on a substrate and a chromium-containing top layer located on the adhesion-promoting layer, wherein: - the substrate consists of a material selected from the group comprising copper, nickel-free copper alloys, plastics material coated with copper, steel coated with copper and diecast zinc products coated with copper; - the adhesion-promoting layer contains at least 99.9 wt.% copper; and - the adhesion-promoting layer is located directly on the substrate and the top layer is located directly on the side of the adhesion-promoting layer that is remote from the substrate.
