摘要
选用 MM- 2 0 0型摩擦磨损试验机测定了不同载荷条件下 WSi2 /Mo Si2 复合材料与 45 #钢配副的干摩擦磨损性能 ,采用扫描电子显微镜和 X射线衍射仪分析讨论了其磨损机理 .结果表明 :WSi2 /Mo Si2 复合材料在高于 80 N载荷条件下具有比较稳定的摩擦磨损性能 ;在 85～ 1 3 5 N范围内其摩擦磨损性能优于 Mo Si2 材料 .WSi2 /Mo Si2
The friction and wear properties of WSi 2/MoSi 2 composites in dry sliding against AISI 1045 steel were investigated with an MM 200 friction and wear tester. The worn surfaces were analyzed by means of scanning electron microscopy, X ray diffraction and electron probe microanalysis. Results showed that WSi 2/MoSi 2 composite had more steady friction and wear behavior than MoSi 2 at a load above 80 N. Especially, they showed better friction and wear behavior than MoSi 2 in a load range of 85 135 N. This was mainly attributed to the different microstructures and wear mechanisms of the two kinds of materials. WSi 2/MoSi 2 composite was dominated by brittle fracture and adhesion in sliding against the steel.
