中文摘要：

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。

英文摘要：

The wear performance of Al2O3particle-reinforced Al-Mn composite and eutectic Al-Mn alloys research by M-2000 wear tester.In the experiment： prepared Al2O3 particle-reinforced Al-2%Mn composite and Al-Mn alloys,got the data of lost weight of the composite the picture of surface of wearing in various loading.The experimental result：with the increasing of loading the Lost weight of composite is increasing;effect of wear performance with the corrosive and wearing media in sliding friction;the composites have better wear performance than the ally.
