摘　　要：文章通过对比不同稀释率及热处理制度CO_(2)气体保护药芯焊丝电弧焊镍基合金堆焊层的晶间腐蚀试验结果,结合失重法及金相法分析了影响镍基合金焊材堆焊层耐晶间腐蚀能力的因素,并提出通过严格正确的取样位置及合理控制堆焊层热处理制度来提高其耐腐蚀能力的建议。This paper through the comparison of different dilution rate and heat treatment of FCAW nickel based alloy surfacing layer inter-granular corrosion test results,combined with the weight loss method and metal analysis the influence factors of nickel alloys surfacing layer of inter-granular corrosion resistance,and put forward by strictly correct sampling position and reasonable control of the surfacing layer heat treatment the system to improve the corrosion resistance of the proposal.
