摘　　要：简述了Ti(C,N)金属陶瓷的典型结构,着重介绍了过渡族金属碳化物添加剂(如纳米TiC/TiN、Mo2C、WC、TaC、NbC、VC、Cr3C2等)对Ti(C,N)金属陶瓷材料微观结构和力学性能的影响。指出通过合理添加金属碳化物添加剂,可望制备出综合性能优异的Ti(C,N)金属陶瓷。Description is made of the typical structure of the Ti（C, N）-based cermet, focusing on the influ- ence of the additives of transitional metal carbide, such as nano-crystal TiC/TiN, Mo2C,WC,TaC, NbC, VC,CraC2 on the microstructure and mechanical property of Ti（C,N）-based cermet. It is feasible to pro- duce Ti（C,N）-based cermet with excellent performance by proper addition of carbide additives.
