Abstract

Abstract

In view of the quality problems of manual TIG overlaying of cobalt-based alloy, the additive manufacturing process of cobalt-based alloy is studied, especially the optimization of laser additive manufacturing process parameters. Then a series of experiments, including hardness, wear resistance, corrosion resistance etc., are carried out on the cobalt-based alloy additive manufacturing layer and compared with the manual TIG surfacing layer. The results show that the microstructure of the laser additive manufacturing layer is more refined, the hardness is more uniform, the wear resistance and corrosion resistance are better than that of the manual TIG surfacing layer.
