用M-2000摩擦试验机对共晶铝锰合金和对应Al2O3颗粒增强铝锰基复合材料滑动摩擦磨损性能进行了研究,获取了其在不同载荷下的磨损量和磨损表面形貌。结果表明,材料的磨损量随着载荷的增加而增加,复合材料的磨损性能要优于相同含锰量的铝合金。 The sliding friction and wear properties of eutectic Al-Mn alloy and corresponding Al2O3 particles reinforced Al-Mn matrix composites were studied by using M-2000 friction tester. The wear amount and wear surface morphology under different loads were obtained. The results show that the wear amount of the material increases with the increase of the load, and the wear performance of the composite is better than that of the aluminum alloy with the same Mn content.
