A method for applying a large amount of four-layer layer structure on a substrate, and substrate with a large amount of four-layer layer structure

摘要

A substrate (1) with a metallic surface (2) has a provided on the multiple layer structure (3) comprises at least two different layers (4, 5) which, in the direction of periodically repeated sequence to one another and parallel to the surface (2) of the substrate (1) are arranged. The layer structure (3) is constructed as a diffusion layer, wherein first layers (4) form an intermetallic matrix, in which layers (5) from a second, preferably intermetallic phase are designed to be periodically. In the case of a process for the production of a large amount of four-layer layer structure (3) comprises at least two different layers (4, 5) on a metallic surface (2) of a substrate (1), to the surface (2) of the substrate (1) at least one metallic layer (6) is applied. The coated substrate is then subjected to a heat treatment (1) and the multiple layer structure (3) during the heat treatment is produced by diffusion. The materials of the metallic layer (6) and the surface (2) of the substrate are in this case matched to one another in such a way that, by means of the heat treatment are first layers (4) as an intermetallic matrix can be produced, in which layers (5) from a second, preferably intermetallic phase be designed to be periodically.
