Effect of the parameters in high\|temperature wear test on high\|temperature wear resistance of WC/steel composite material (GHJ\|2) in different condition of heat treatments were studied and analyzed. The results showed higher high\|temperature wear resistance of WC/steel composite material after quenching at 1050℃ and tempering at 480℃ and at 640℃. The high\|temperature wear resistance (ε) were 13 2 and 12 4, and the relative high\|temperature wear resistance (ε′) of WC/steel composite material were ...
