采用ICP对304不锈钢表面黑色腐蚀物的分析

摘要

Analysis of the black corrosion on 304 stainless steel surface were done using ICP, We found that the proportion of each metals in the black corrosion were ： Fe 13.55%, Cr 23.29%, Ni 57.54%--with rich Ni, poor Fe, poor Cr characteristics.The solubility of the black corrosion under different conditions were discussed, and the influence to alkali liquor quality were speculated.%通过采用ICP对304不锈钢表面黑色腐蚀物的分析，发现黑色腐蚀物具有富Ni、贫Fe、Cr的特征，各金属的含量分别达到：Fe13．55％、Cr23．29％、Ni57．54％。分析了黑色腐蚀物在不同环境下的溶解性，并推测了对碱液质量的影响。
