Abstract
We investigated the structure change, surface properties (roughness, porosity, and hardness), tribological, and electrochemical performances of HVOF sprayed Ni-20Cr-10W-9Mo-4Cu-1C-1B-1Fe (Diamalloy-4006) coatings before and after laser irradiation. The results showed that the friction and wear resistance of the coatings were improved significantly with an optimized laser irradiation process. The improvement can be attributed to the improved roughness and hardness, as well as the formation of oxides Cu x O and Cr2O3 tribofilms. With the laser irradiation treatment, the local corrosion of the coating had a decrease and the selective corrosion resistance of the Diamalloy-4006 coating was improved as a result of the decreasing the size and number of the pores, especially compact interface achieved by laser irradiation.
