摘要：

WC-5TiC-15Co cermets were prepared via novel technology - reactive sintering. In case of reactive sintering the elemental powders of tungsten, titanium, cobalt and carbon black are activated through ball-milling and then the synthesis of carbide occurs in the same cycle with the sintering of the cermet. Carbon content in initial powder mixture has crucial effect on properties of reactive sintered WC-based cermets. This paper investigates the erosion wear of the WC-5TiC-15Co cermets. Wear resistance dependent on the carbon content as well as wear mechanism of reactive sintered and conventional cermets are exhibited.
