Abstract
A method is provided for producing a wear-resistant layer on a metal base. A material, containing about 10 to 50% by weight of TiC in the form of sintered or agglomerated particles in which TiC is dispersed in a matrix alloy selected from the group consisting of iron, nickel and cobalt alloys, is applied to a metal base by thermal spraying. The sprayed-on layer is subjected to heat treatment to provide precipitation hardening by virtue of the precipitation of TiC as uniformly dispersed fine grains. The sintered or agglomerated particles containing TiC have a grain size of -150 to +37 .mu.m. The layer is applied by autogeneous flame spraying to a thickness of at least about 1 mm.
