摘要
采用原位法制备Mg2Si/AM60复合材料,研究了不同质量分数的Si粉对Mg2Si/AM60复合材料摩擦磨损性能的影响。结果表明,Si质量分数增加,复合材料硬度增加,其磨损量随之减小,磨损性能得到显著加强。外加载荷增大,复合材料磨损量持续增加。与基体AM60相比,Mg2Si/AM60复合材料有效推迟微量磨损向严重磨损转变的时间。
Effects of Si contents on friction and wear performance of in-situ Mg2Si/AM60 composites were investigated. It is found that,with increasing in Si content,the weight loss of the composites is decreased as a result of the increase of the hardness,greatly improving the wear behavior of the composites. With the loading increase,the weight loss of the composites is increased. Compared with AM60 matrix,the transformation time of trace-wear into severe wear of the composites is effectively postponed.
