Metal substrates with laser-induced MMC coating.

摘要

In a material consisting of aluminium or aluminium alloys with a wear-resistant and load-bearing MMC surface layer, the MMC layer has a layer thickness of between 200 mu m and 3 mm and contains homogeneously distributed SiC particles in an AlSi matrix, which is hypereutectoid with respect to the Si content, with primary Si crystals. The material is particularly suitable for applications, where wear or weight are critical and in which additionally a high strength of the material is demanded. The invention also relates to the process for the laser-induced production of the wear-resistant and load-bearing MMC layers (6) on substrates (3) of aluminium or aluminium alloys.
