采用真空热压烧结工艺制备了SiC颗粒体积分数分别为10%、20%、30%和40%的ZL101A复合材料,对其硬度与室温干摩擦磨损性能进行了测试分析,同时对其磨损机理进行了探讨。结果发现,复合材料硬度随着SiCp的增加而增加,当SiCp体积分数达到30%时,硬度达到最大值。基体ZL101A的主要磨损机理为粘着磨损,而SiCp/ZL101A复合材料的磨损过程是粘着磨损和磨粒磨损两种机制共同作用的结果。随着SiC颗粒体积分数的增加,粘着磨损所占的比例逐渐降低,从而使SiCp/ZL101A复合材料的磨损性能得以提高。
ZL101A composites with SiC particle volume fraction of 10%, 20%, 30% and 40% were prepared by vacuum hot-pressing sintering process. The wear resistance of ZL101A composite was tested and analyzed. Meanwhile, Exploring. The results show that the hardness of composites increases with the increase of SiCp, and reaches the maximum when the volume fraction of SiCp reaches 30%. The main wear mechanism of the matrix ZL101A is adhesive wear, while the wear process of SiCp / ZL101A composite is the result of the joint action of adhesive wear and abrasive wear. As the volume fraction of SiC particles increases, the proportion of adhesive wear gradually decreases, so that the wear properties of SiCp / ZL101A composites are improved.
