TiCP/3Cr13复合材料显微组织及耐磨性的研究

摘要

The microstructure and wear-resisting properties of TiCP/3Cr13 composites are investigated in this paper.The friction and wear mechanism are also discussed.The results show that when the volume fraction of TiC was lower than 8%,the distribution of TiC particle in the microstructure is uniform and no apparent particles segregation and microdefects are observed.The wear-resisting properties of compo-sites increases with the increasing of TiCP volume percent,and when it is up to a constant volume percent,it will not increase.%研究了TiC颗粒增强3Cr13钢基复合材料的显微组织和摩擦磨损特性，探讨了TiC颗粒增强3Cr13钢基复合材料的摩擦磨损机理。结果表明，当TiCP颗粒的体积分数小于8％时，显微组织中TiCP颗粒分布均匀，没有出现颗粒的团聚及由于引入TiCP颗粒而形成的组织缺陷。随着TiC颗粒体积分数的增加，复合材料的耐磨性增加，达到一定的体积分数时，其耐磨性几乎不再增加。
