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.

Method for the formation of a high-strength and wear-resistant composite layer

A process for joining or welding components made from case-hardened steel to one another or to components made from cast iron uses a nickel-containing filler. The components are not prepared for the welding operation, i.e., the components do not undergo at least partial abrasion of surfaces to be joined.
