将铜粉与不同体积分数的Ti₃AlC₂粉体混合，采用放电等离子烧结工艺在不同温度（850，900℃）保温20 min制备Ti₃AlC₂/Cu复合材料，研究了Ti₃AlC₂含量和烧结温度对复合材料显微组织、相对密度、硬度和摩擦磨损性能的影响。结果表明：在900℃保温20 min烧结后，随Ti₃AlC₂含量的增加，其在铜基体中逐渐呈不均匀分布，复合材料的相对密度减小、硬度增大；同时，复合材料的磨损率和摩擦因数均降低，耐磨性能增强，磨损机制按照犁削磨损和黏着磨损→黏着磨损和磨粒磨损→犁削磨损和轻微黏着磨损依次转变。900℃烧结所得复合材料的相对密度高于850℃烧结的，摩擦因数则低于850℃烧结的。

The Ti₃AlC₂/Cu composite was prepared by spark plasma sintering powder mixtures of Cu and Ti₃AlC₂ with different volume fractions at different temperatures (850,900℃) for 20 min. The effects of Ti₃AlC₂ content and sintering temperature on the microstructure, relative density, hardness and frictional wear performance of the composite were investigated. The results show that after sintering at 900℃ for 20 min, with the increase of Ti₃AlC₂ content, the uneven distribution of Ti₃AlC₂ in Cu matrix became more and more obvious; the relative density of the composite decreased and the hardness increased. Meanwhile, the wear rate and friction coefficient of the composite decreased, indicating the increase of wear resistance, and the wear mechanism changed in the order of cut wear and adhesive wear, adhesive wear and abrasive wear, and cut wear and slightly adhesive wear. The relative density of the composite sintered at 900℃ was higher and the friction coefficient was lower than those at 850℃.
