摘　　要：采用反应烧结技术制备了Ti3AlC2材料,研究了该材料的载流摩擦磨损性能。结果表明,随电流强度的增大,Ti3AlC2材料的摩擦系数和磨损率均呈现增加的趋势,在80 A时分别达到最大值0.47和6.3×10-6mm3/N·m。当电流为0时,磨损以氧化膜的轻微划痕和粘着磨损为主;随着电流的增加,磨损逐渐转变为以微电弧烧蚀和机械磨损为主。The material Ti3AlC2 was prepared by a reaction-sintering technology, and the current-carry friction and wear properties of the material were investigated. The results show that the friction coefficient and wear rate of Ti3AlC2 increase with the increase of current intensity, and they achieve the maximum of 0.47 and 6.3×10-6mm3/N·m, respectively, when the current intensity is elevated to 80 A. The wear mechanisms are mainly slight scratch and adhesive wear of oxidation film when the current intensity is 0, while the wear mechanisms transform gradually into the micro-arc ablation and mechanical friction with the increase of the current intensity.
