摘要

通过粉末冶金法制备了SiC

增强铝基复合材料并对其进行了热挤压变形处理

研究了不同热挤压参数对SiC

/铝基复合材料磨损性能的影响。结果表明

SiC

颗粒分布的均匀性对复合材料磨损性能影响较大

热挤压SiC

/铝基复合材料的磨损量随SiC

含量的增加先减小后增大;磨损速度及磨损载荷的增大使材料的磨损速率增加。Sn的添加能够提高SiC

/铝基复合材料的耐磨性能

但Sn含量的变化对热挤压SiC

/铝基复合材料的磨损性能影响不大。

Abstract

SiC

reinforced aluminum matrix composites were prepared by means of powder metallurgy and hot extrusion deformation

and the friction and wear properties of the composites prepared were investigated.The results show that the homogeneity of SiC

particle has great influence on the wear properties of the composites.The wear loss of the composites is increased firstly and then decreased with the increase of the SiC

content.With increasing in the wear rate and the wear loading

the wearing rate of the composites is increased.The wear properties of the SiC

reinforced aluminum matrix composite can be improved with Sn addition

however

Sn addition change can little affect the wear behavior of the hot extruded composites.
