摘要

以Al-Mg2Si合金为基体

添加铜包石墨颗粒及Al-Ce中间合金制备了新型含石墨铝合金。研究了含石墨铝合金铸态及固溶时效后的微观组织

并测定了其布氏硬度;重点考察了其在不同载荷、乙醇润滑条件下的磨损性能。结果表明

石墨均匀分布于铸态合金基体中

固溶时效后

组织细化

硬度提高。在载荷为100N、乙醇滴入量为20mL/min时

铝合金表面磨损轻微。摩擦界面的石墨颗粒及乙醇的综合润滑作用影响了合金的磨损性能。

Abstract

The copper-coated graphite and rare element（Ce）were added into the Al-Mg2 Si matrix alloy

and the graphite-contained aluminum alloy was prepared.The microstructure of the as-casted and solution-aging treatment was observed and the hardness was tested.The wear behavior under different loads and ethanol droplets were evaluated.The results show that the graphite particle is distributed uniformly in the as-cast alloy and the microstructure of the alloy is refined after solution and aging treatment with improvement of the hardness.Under the load of 100 N

20mL/min droplets of ethanol

wear loss of the prepared aluminum exhibits mild.The graphite particles and the ethanol boundary lubricated film affect the graphite-contained aluminum alloy.
