摘要
采用搅拌摩擦表面加工技术在H62铜合金表面制备了SiC/H62铜合金表面改性层,并对改性层进行了微观组织、耐磨性和硬度等分析。结果显示,获得的改性层晶粒得到很好的细化,改性层表面无缺陷;改性层磨损形式主要是磨粒磨损和犁沟磨损,同时也伴随着少量的粘着磨损;改性层硬度明显高于母材。
The surface modification layer of SiC/H 62 copper alloy are obtained by friction stir processing technol-ogy. The microstructure, wear resistance and hardness of the modified layer are analyzed. The results show that the grain of the modified layer is refined. The surface of the modified layer without defect. The modified layer wear form are mainly abrasive wear and furrow wear, but also accompanied by a small amount of adhesive wear. The modified layer hardness is significantly higher than the base metal.
