摘　　要：以WC颗粒增强高铬钢基表面复合材料、钛颗粒增强Al_(2)O_(3p)/45钢基复合材料为例,在不同滑动速度、载荷下,用型号为MMU-5G屏显型端面高温摩擦磨损测试机测试材料的摩擦学性能(主要通过摩擦因数与磨损率体现)。结果表明:不同滑动速度下,WC颗粒增强高铬钢基表面复合材料的摩擦因数小于高铬钢,Ti-Al_(2)O_(3p)/45钢复合材料的摩擦因数小于Al_(2)O_(3p)/45钢复合材料;不同载荷下,WC颗粒增强高铬钢基表面复合材料的磨损率均小于高铬钢,Ti-Al_(2)O_(3p)/45钢复合材料的磨损率小于Al_(2)O_(3p)/45钢复合材料。对比之下,WC颗粒增强高铬钢基表面复合材料、Ti-Al_(2)O_(3p)/45钢复合材料的耐磨性更好。The tribological properties,including friction coefficient and wear rate, were investigated on the WC particle reinforced high chromium steel matrix surface composite and titanium particle reinforced Al_(2)O_(3p)/45 steel matrix composite under different sliding speeds and load conditions with the aid of MMU-5 G screen high temperature end face friction and wear tester. The results show that the friction coefficient of WC particle reinforced high chromium steel matrix composites is lower than that of high chromium steel matrix composites,and the friction coefficient of Ti-Al_(2)O_(3p)/45 steel composites is lower than that of Al_(2)O_(3p)/45 steel composites. Under different load conditions,the wear rate of WC particle reinforced high chromium steel matrix surface composite is lower than that of high chromium steel,and the wear rate of Ti-Al_(2)O_(3p)/45 steel composite is lower than that of Al_(2)O_(3p)/45 steel composite. Compared with Al_(2)O_(3p)/45 steel composite,WC particle reinforced high chromium steel matrix surface composite and Ti-Al_(2)O_(3p)/45 steel composite exhibit better wear resistance.
