摘要(Abstract)：

利用搅拌铸造法制备了Mg2B2O5w/6061Al复合材料,研究了在不同压力(2、5、8、11和15 N),滑动速度为0.1 m/s条件下,T6热处理对Mg2B2O5w/6061Al复合材料干摩擦条件下磨损性能的影响。结果表明:T6热处理可以使Mg2B2O5w/6061Al复合材料的硬度值大幅度提高,但是对提高复合材料的耐磨性能不是很显著,可见,T6热处理不能作为Mg2B2O5w/6061Al复合材料的最佳热处理工艺;在文中的试验条件下,6061Al合金的主要磨损机制为粘着磨损,而铸态复合材料的主要磨损机制为磨粒磨损,T6热处理后的复合材料主要以磨粒磨损及粘着磨损为主。
