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，从而改善了不锈钢材料焊接接头的耐蚀性
The effect of rare earth on the corrosion resistance of caustic soda caustic soda in Inner Mongolia was investigated by high temperature electrochemical method. The results show that the rare earth elements can be transferred into the weld metal by proper coating recipe and welding process, and the proper amount of rare earth elements can change the polarizability of the anodic polarization curve of the stainless steel welded joint, thus improving the resistance of stainless steel welded joints Erosive
