Abstract

A process for forming a high-strength, wear-resistant composite layer on the surface of an aluminum alloy substrate from an applied additive material. The additive material consists of an alloy or powder mixture which contains aluminum, silicon and at least 15% by weight of iron. Irradiating the alloy powder or powder mixture which has been positioned on the surface of the aluminum alloy substrate using a laser melts together with the alloy or powder mixture and a superficial part of the aluminum alloy substrate.
