摘要
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．
Aluminosilicate short fibre reinforced Al 12Si alloy composite was fabricated by squeeze casting technique. The wear behaviors of Al 2O 3·SiO 2/ZL109 composite and ZL109 alloy were investigated under dry conditions. The experimental results showed that the increased wear resistance of Al 2O 3·SiO 2/ZL109 was attributed to the formation of a hardened layer in subsurface where the realignment and redistribution of fragmented eutectic phase and fragmented aluminosilicate fibre occurred during dry sliding.
