Abstract
Protective coatings with hard metal-like wear properties could be obtained by laser beam surfacing of powder mixtures consisting of coarse-grained tungsten carbide and a nickel or cobalt hard alloy. The microstructure of the clad composite layers was investigated by metallography and SEM. The four coating systems produced were found to differ strongly in the degree of partial carbide dissolution and the formation of new hard phases. This also influences the hardness and wear behaviour.
