Abstract
The invention relates to a surface layer which comprises a plurality of layers, of which one layer is a ceramic wear-resistant layer and another layer is a transition layer to a metallic substrate element. The transition layer comprises intermetallic phases and is formed by a reaction from the materials of the substrate element and of the ceramic layer.
Claims15
A surface layer, comprising:
- a substrate element;
- a plurality of layers, of which one layer is a transition layer to the substrate element;
- wherein the surface layer includes a ceramic layer containing a chemically bonded metal, and wherein the substrate element is a metallic substrate element;
- and
- wherein the transition layer contains intermetallic phases comprising the metal of the substrate element and the metal of the ceramic layer.

A process for producing a surface layer comprised of a plurality of layers, of which one layer is a transition layer to a substrate element, the process comprising the acts of:
- applying a ceramic layer to a metallic substrate element;
- causing a reaction between the metal of the substrate element and the ceramic layer by introducing energy;
- and
- producing, during said reaction, a transition layer containing intermetallic phases.
