Abstract  In order to improve the bending strength of high entropy alloy bonded cermet, SiC whiskers were added in Al0.1CoCrFeNiV0.1 bonded Ti(C,N) cermet, and the effects of SiC whiskers on the phase, microstructure, mechanical performance, and friction and wear performance of cermet were studied. The results show that few addition of SiC whiskers can promote the solid solution of carbide and refine the Ti(C,N) grains, but the excessive addition brings clusters of solid solution. When w(SiC)=1%, the bending strength and fracture toughness of cermet are evidently improved, the increasing rate of bending strength is 21.4%; during the process of friction, the cermet forms continuous and smooth tribolayer on the surface, exhibiting low and stable friction coefficient with wear ratio nearly to 10-6 level.
