Abrasive Wear Resistance of Ultra-fine Structured WC-12Co Coating Deposited by HVOF AITranslate
Abstract AITranslate
Using spherical shell shaped WC-12 Co composite powder prepared by spray conversion as raw materials,ultra-fine structured WC-12 Co coating was prepared on 45#steel substrate by high velocity oxygen-fuel(HVOF)spray.The microhardness and fracture toughness of the coating were investigated.The phases,microstructure and wear resistance of the coating were analyzed by XRD,SEM and wear testing machine.The results indicate that moderate decarbonization reaction of WC-12 Co composite powder with porous spherical shell occurs during HVOF spraying.The coating contains not only WC and W2C phases,but also a small amount of W phase.The coating is highly densified and shows rock stratum structure,with average microhardness HV0.3 and fracture toughness of 1 205.5 and 4.96 MPa·m^1/2,respectively.During wearing,the binding phase of the coating is ploughed by SiO2 to form discrete grooves,and the fine WC grains from stripping and cracking of WC grains become new abrasives,which grind coarse grains or accumulate in cracks to aggravate cracking.
