WC-10Co-4Cr coatings were prepared on 45#steel by plasma spraying(APS),supersonic plasma spraying(SAPS)and high velocity oxy-fuel thermal spraying(HVOF),respectively.The porosity,microhardness,and wear resistance of the three coatings were analyzed and compared.The results show that the two coatings prepared by SAPS and HVOF have similar performance and single phase composition similar to the powders.Compared with the coating prepared by APS,the two coatings prepared by SAPS and HVOF have higher density and microhardness and better wear resistance.
