  • Laser cladding of Co base alloy on the nuclear valve sealing surface are performed with a 5 kW CO 2 transverse flowing laser. The microstructure and the high temperature impact slide wear resistance of the laser cladded coating and the plasma cladded coating are studied. The results show that the microstructure, the dilution rate and the high temperature impact slide wear resistance of the laser cladded coating have obvious advantages over the spurt cladding processing.
