SiCp颗粒增强AZ80镁合金的摩擦磨损特性

The Friction and Wear Characteristics of SiCp Particles Reinforced AZ80 Magnesium Alloy Composite

本文研究了喷射搅拌铸造法制备的ＳｉＣｐ／ＡＺ８０复合材料的摩擦磨损性能。结果表明：复合材料的耐磨性优于基体合金；复合材料磨损表面存在由ＧＣｒ１５对磨环转移的富铁层，使复合材料－ＧＣｒ１５摩擦副的摩擦系数比ＡＺ８０－ＧＣｒ１５摩擦副低；复合材料的对磨环磨损量大于基体合金的对摩环磨损量，但复合材料摩擦副的总磨损量比基体合金摩擦副的小。

The friction and wear characteristics of SiCp/AZ80 composite prepared by splaystirring method have been investigated. The results indicated that the wear resistance ofthe composites was superior to that of AZ80 matrix-alloy. Because of existence of ironenriched oxide layer transferred from GCr15 mating onto the wear surface of composite,the friction coefficient of SiCp/AZ80-GCr15 system is lower than that of AZ80-GCrlssystem, while the wear rate of the grinding ring with composite is more than that withmatrix, but the total wear rate of SiCp/AZ80-GCr15 system is less than that of AZ80GCr15 system.
