摘　　要：以含有镧铈混合稀土和石墨烯的金属复合粉末作为熔敷材料,对小型齿轮Cr12Mo V精冲模具进行了激光熔敷处理,并对激光熔敷层的显微组织、物相组成以及模具的耐磨损性能和模具寿命进行了分析。分析结果表明,激光熔敷层组织均匀细小,由γ(Ni)相、Ni Ti相、WC相、W_2C相、Co_3W_3C相、Co相和石墨烯组成;激光熔敷处理使模具耐磨性和使用寿命得到明显提高。Taking the metal composite powder containing cerium and lanthanum mixed rare earth and graphene as deposited material, the small gear Crl2MoV fine blanking mold was modified by laser cladding, and the microstructure, phase composition, mold wear resistance and mold life of laser cladding layer were analyzed. The analysis results show that laser cladding layer is composed of T（Ni） phase, NiTi phase, WC phase, W2C phase, C03W3C phase, Co phase and graphene, which are in homogeneous and fine. The wear resistance and service life of the mold by laser cladding processing obviously improve.
