摘　　要：采用横流CO2激光器,对AM60B镁合金进行激光熔凝处理,同时改变激光加工工艺参数,得到不同的熔凝组织。讨论了各工艺参数对熔凝区尺寸的影响规律,并分析了熔凝区组织性能之间的关系。结果表明,激光熔凝后,晶粒得到细化,硬度提高约50%,耐磨性提高约60%。Laser melting on AM60B alloy was carried out using cross-flow CO2 laser.The laser process parameters were changed.The influence of processing parameters on the size of laser melting zone was discussed.The relationship between structures and properties of the laser melting zone was analyzed.The results show that after laser melting,the crystalline grain can be fined,and the hardness increases by 50%,the wear resistance improves by 60 %.
