Influence of CeO2 on the Microstructure and Wear Resistance of M80S20 Thermal Spray and Thermal Spray Welding Coatings

The influence of rare earth oxide CeO2 on microstructure and wear resistance of M80S20 thermal sprayand thermal spray welding coatings is studied using optical microscope,scanning electron microscope,X-rayenergy dispersion spectroscope,X-ray diffractometer and wear testing machine.The results show that the addi-tion of 8% CeO2 can improve the microstructure,microhardness and wear resistance of coatings significantly.
