摘　　要：本文以钛粉、钼粉熔炼制备TiMo合金,通过理论配碳制备了TiMoC陶瓷粉体。以TiMoC为添加剂通过粉末冶金工艺制备了TiC陶瓷基复合材料。采用XRD、SEM和EDS的方法对粉体及复合材料进行了表征。研究结果表明,TiMo合金和TiMoC陶瓷粉体均为立方晶体结构,以TiMoC添加剂制备的TiC陶瓷基复合材料显微组织中TiC硬质相被富Mo的(Ti,Mo)C环形壳包裹,显微组织得到细化,力学性能得到提高。TiMo alloy was melted with titanium and molybdenum powders. The TiMoC ceramic powder was prepared by TiMo and graphite powders with stoichiometry. TiC ceramic composite was prepared with addition of the TiMoC using powder metallurgy technique. The powders and composite were characterized by methods of XRD,SEM and EDS. The results showed that TiMo alloy and TiMoC powder were cubic crystal structure. The microstructure and properties of TiC ceramic composite with TiMoC addition were better due to the （Ti,Mo）C shell structure.
