Abstract

In a wear protection layer comprising, disposed on a substrate, a plurality of individual layers including a first individual layer of a metallic hard material disposed directly on the substrate, periodically repeated composite arrangements of three individual layers comprising two individual layers of different metallic hard materials and one individual layer consisting of a covalent hard material are disposed on the first individual layer of a metallic hard material whereby the mechanical, physical and chemical properties of the metallic hard materials are combined with the properties of the covalent hard materials.
