This paper studies the effect of the microstructure and hardness of the nickel based hardfacing alloy on wear resistance of deposit layers when different alloy elements are added. Results show that when subject to abrasive wear, if the abrasive particles are silicon carbide, the increase of the volume fraction of hard phase could improve the wear resistance of the deposit layers. On adhesive wear, the niobium added specimens form some spherical niobium carbide particles in the matrix of the deposit layer which reduced the friction coefficient of the specimens. The addition of carbon and chromium can enhanced macrohardness and wear resistance by forming a continuous phase in the microstructure of the deposit metal.
