摘　　要：研究了不锈钢表面镍铬激光熔敷层的组织与耐磨性能。结果表明，熔敷层组织细小均匀，有硬化相存在，并具有良好的耐磨性能。The microstructure and wear resiStance of laser cladding layers of Ni and Cr onthe surface of stainless Steel were studied.It is shown that the microstructure of lasercladdins layers is fine and homoSenous.There are hardening phases.The wear resistance ofthe cladding layer is improved markedly.

关 键 词：不锈钢 镍铬合金 激光熔敷 耐磨性
