焊接接头晶间腐蚀
welded joint intercryctalline corrosion
honjle」}etou jingj旧n fush{焊接接头晶间腐蚀(welded joint intererys-talline eorrosion)在焊接接头处出现的沿晶粒边界发生的腐蚀现象。外观仍可有金属光泽，但实际上晶粒已失去联系，钢质已变脆。在奥氏体不锈钢部位有焊缝晶间腐蚀、敏化区腐蚀和刀状腐蚀等三种不同部位的晶间腐蚀。关于奥氏体不锈钢的晶间腐蚀机理有多种学说，其中以碳化物(如er23e。或(er、Fe)23e。等)在晶界沉淀现象的“贫铬理论”比较为人们所接受。所以为防止这类晶间腐蚀尽量降低含碳量，使焊缝金属含有一定量的稳定元素(如钦、妮等)以防止或降低晶界Cr23C。的形成。此外，焊缝的组织状态也有影响，单相奥氏体组织的焊缝有利于柱状晶的发达，出现贫铬层后会使腐蚀贯穿于晶粒之间，若焊缝为奥氏体了加高温铁素体占的双相组织，由于树枝状被打破，不能构成集中的腐蚀通道。高铬铁素体也会有晶间腐蚀，但与奥氏体钢不同的是从高温急冷下来即有晶间腐蚀倾向，可通过650一85oC加热、缓冷使铬扩散均匀化来消除贫铬层，防止晶间腐蚀。 (许祖泽)
