Abstract The WC-10Co-4Cr powders were prepared by using rapid agglomerate sintering method, and the coatings were sprayed onto steel substrate by high velocity oxygen fuel (HVOF) technology. A study was conducted with regard to the effects of sintering temperature on the WC-10Co-4Cr powders, as well as on the microstructure and wear resistance of WC-10Co-4Cr coatings. As suggested by the results, when the sintering temperature was raised from 1 250 ℃ to 1 450 ℃, the density of WC-10Co-4Cr powders increased, the average particle size of powders decreased, and the uniformity of them declined. With the increase of powder sintering temperature, the internal defects of the WC-10Co-4Cr coa-tings increase, leading to weakened wear resistance. In this case, the primary wear mechanism varied from the micro-cutting of the binder phase to delamination wear.

Key words： WC-10Co-4Cr rapid agglomerate sintering method high velocity oxygen fuel wear resistance
