采用热丝脉冲TIG工艺在AISI 4130基体表面堆焊Inconel 625合金,获得了平坦、连续、无缺陷的堆焊层.借助光学显微镜、XRD、SEM、EDS对堆焊层的微观组织、相组成、成分进行了分析.堆焊层主要由γ-Ni基体、分布在晶间不规则的Laves以及颗粒状的MC组成;晶体形态对Laves相的分布特征有着重要的影响,不同的晶体形态对应着Laves相的不同分布特征.堆焊层与基体、层间融合界面附近合金元素含量变化显著,层内部元素分布比较均匀,堆焊层表面Fe元素质量分数为1.81％.同时,采用动态极化曲线法对堆焊层与基体的耐腐蚀性能进行了研究.结果表明:其耐腐蚀性能与铸态Inconel 625基本相当,能够满足耐腐蚀要求.
