摘要
通过焊条药皮向１Ｃｒ１８Ｎｉ９Ｔｉ不锈钢焊缝中过渡稀土，用高温电化学方法研究了稀土对焊缝耐内蒙古天然碱苛化烧碱腐蚀性能的影响。结果表明：采用适量的焊条药皮配方和焊接工艺可使稀土元素过渡到焊缝金属中，适量稀土元素改变了不锈钢焊接接头阳极极化曲线的极化率。
Rare earth has been introduced into the welding seam of 1Cr18Ni9Ti stainless steel by adding it to welding agent in this paper The effects of rare earth on the welding corrosion resistance against the caustic soda of inner mongolia were researched by high temperature electrochemistry method The results show tha trare earth element can be introduced into the welding seam metal by adding proper rare earth elements and using welding process, polarization rate of positive electrode polarzation curve of 1Cr18Ni9Ti stainless steel welding joint can be changed by adding appropriate rare earth element, and the corrosion resistance of welding joint can be improved consequently
