摘要

以ZL108铝合金为基体

添加Cu包覆石墨及稀土（Ce）

采用机械搅拌制备了Cu包覆石墨/Al复合材料。考察了不同Cu包覆石墨含量的Cu包覆石墨/Al复合材料的组织、硬度及磨损性能。结果表明

试验条件下

在2%

%的Cu包覆石墨的范围内

石墨分布趋于均匀。制备的Al-4Cu包覆石墨/Al复合材料具有较高的硬度及较好的耐磨性。添加石墨使复合材料的磨损机制由磨粒磨损转变为剥层磨损。

Abstract

The cast aluminum/graphite composites were prepared with Cu-coated graphite particles and rare element adding into the Al-Si alloy（ZL108）matrix through mechanical stirring method.The microstructure

hardness and wear behavior of the composites prepared with different Cu-coated graphite content were investigated.The results show that the dispersion of Cu-coated graphite is uniform when the Cu-coated graphite content is 2%

%.The cast aluminum/4% Cu-coated graphite exhibits a higher hardness and better wear resistance.The dominated wear mechanism is changed from abrasive wear for the cast aluminum 0% Cu-coated graphite to delaminated mechanism for cast aluminum 4% Cu-coated graphite composites.
