| 摘 要： | 采用粉末冶金法制备了添加纳米SiC晶须（n-SiCw）的铜基纳米复合材料（SiCw／Cu）。研究了复合材料的显微组织、密度、硬度与n-SiCw含量之间的关系，通过球／盘式摩擦磨损试验机研究了SiCw／Cu复合材料的摩擦磨损性能。结果表明：随n-SiCw含量增加，基体中孔隙增多，并出现n-SiCw的偏聚，复合材料的密度减小，硬度增加；当n-SiCw含量为0．3wt％时，材料的减摩、耐磨性能最好；SiCw／Cu复合材料的磨损机制为疲劳磨损和磨粒磨损，并以疲劳磨损为主。 |

| Abstract: | The nano-SiC, reinforced Cu-based composites are prepared by powder metallurgy processes. The relation of n-SiCw content on the microstructure, the density and the hardness are investigated. The tribological performances of the composites are studied by using ball/disk friction tester. The results indicate that the pores of the matrix increase with increasing of nano-SiCw contents. The densities of the composites decrease and hardness increase with the increase of nano-SiCw contents. The wear rate is at its best when the content of nano-SiCw is 0. 3 wt%. The wear mechanisms of the composites include fatigue and abrasive wear with fatigue wear as main mechanism. |
| Keywords: | Cu-based composites nano-SiC friction and wear powder metallurgy |
