采用挤压铸造法制备了硅酸铝（Ａｌ２Ｏ３·ＳｉＯ２）短纤维增强ＺＬ１０９复合材料，并研究了该材料在干摩擦条件下的磨损行为．结果表明：Ａｌ２Ｏ３·ＳｉＯ２短纤维／ＺＬ１０９复合材料的耐磨机制为纤维断裂并在亚表层重新分布和排列形成高硬度的硬化层．这种硬化层的形成使复合材料具有比基体合金更优越的耐磨性．
The ZL109 composite reinforced by aluminum silicate (Al2O3 · SiO2) short fibers was prepared by squeeze casting method. The wear behavior of ZL109 under dry friction condition was also studied. The results show that the wear mechanism of Al2O3 · SiO2 staple fiber / ZL109 composites is that the fibers are broken and redistributed and arranged in the subsurface to form a hard layer with high hardness. The formation of such hardened layers gives the composites superior wear resistance over the base alloy.
