ABSTRACT:
A method of producing a wear protection coating on a surface of a structural part of titanium or a titanium base alloy comprising applying a metallic nickel layer which adheres to the surface of the structural part and thereafter subjecting the thus coated structural part to a heat treatment to form diffusion layers of Ti.sub.2 Ni and TiNi.sub.3 between the titanium and the nickel. Thereafter, the layer of nickel alone or with the layer of TiNi.sub.3 is removed to leave the titanium part covered by a protection layer of the remaining diffusion layer.
