摘要
焊缝金属和热影响区由于熔化过程而导致焊缝切面上金属成分和显微结构上的微小差别,引起不同区域之间的电化学电位的不同,造成了惰性最小的元素的优先溶解的电池作用而受到了腐蚀。本文也提出了各种不同的防止方法。
Corrosion of weld metal and the heat-affected zone(HAZ) associated with the fusion occurs due to minor differences in composition and micro-structure across the weld joint.These differences lead to electrochemical potential different regions, giving rise to galvanic corrosion with the preferential dissolution of the least-noble element.This paper proposes many different control methods.
