Recently it has been reported that porous Ti-N sprayed coating became fine structure by laser irradiation. In this paper, we have investigated about the effects of infiltrated metals species for the wear resistance of Ti-N remelted layer.
Nonferrous powder metals were sprayed on the substrate of SS400 steel plate in an atmosphere of Ar gas. The coating thickness was about 200μm. Father more, pure titanium was sprayed on the nonferrous spray coating in an atmmsphere of N2 gas. The coating thickness was about 400 μm. The coating specimen consisting of nonferrous layer and Ti-N layer was remelted by laser irradiation in atmosphere of N2 gas. Remelt layers of the coating consisted of fine microstructure and their's hardness values were above HV1000. The wear resistance of Ti-N coating was improved remarkably by remelting.
