| Abstract: | The morphology,microstructure,porosity,hardness,bond strength and abrasive resistance of WC/Co with plasma spraying and high velocity oxy-fuel thermal spraying(HVOF) were analysed and compared.The results show that the coating with HVOF possesses the phase structure of the similar powder,higher density,hardness and good wear resistance,compared with plasma spraying the status of the coating combined with the substrate is greatly improved. |
