摘　　要：在铁基自熔合金基础上分别加入稀土硅铁和铌铁在球墨铸铁基体上进行激光熔覆,通过对熔覆层显微组 织的观察及性能的测试,得出不同熔覆材料对熔覆层组织、性能的影响。Using powder feeding type laser cladding, several claddings were obtained on spheroidal graphite cast iron substrate by cladding alloy power including RE-Si-Fe and Nb-Fe. Effect of cladding material on structure and property of cladding was found by observing the microstructure and testing the property of the cladding.
