摘　　要：采用激光焊接技术连接不锈钢丝和钴铬合金丝,并对比两种异质材料接头添加镍中间层和不添加镍中间层的微观形貌,分析了两种情形下接头的组织特征。结果表明,当镍中间层在一定厚度时,呈现融合充分、晶粒细化、镍元素扩散更加均匀的组织特征。The stainless steel wire and Co-Cr alloy wire are joined together with laser welding,and the micro-structures of two dissimilar joints with or without Ni interlayers are analyzed.The results indicate that the micro-structure has the features such as improved fusion property,finer grain grade and more even diffusion of the Ni element when Ni interlayer is added into the joints.

关 键 词：不锈钢 钴铬合金 激光焊 镍中间层
