Abstract: The Ni60 and Ni60-WC coatings were prepared by flame spray welding and plasma arc surfacing, respectively. The microstructure, phase composition, hardness and wear resistance of the two coatings were studied and compared. The results show that the flame spray welded Ni60 and Ni60-WC coatings had more internal defects and a higher porosity than the plasma arc surfaced coatings. The hardness curves of the spray-welded coatings fluctuated greatly while the hardness of the surfaced coatings distributed evenly. The wear surface of the spray-welded coating was rough and had relatively more scratches, while that of the surfaced coating was smooth. The addition of WC particles improved the hardness and wear resistance of the spray-welded and surfaced coatings. By the flame spray welding, the addition of WC particles increased the porosities of the coatings and resulted in a certain decarbonization of WC particles, while the WC particles had little influence on the porosities of the coatings by the plasma arc surfacing and the WC particles were relatively complete in the coatings.
