摘要
利用腐蚀实验、X-射线衍射分析和扫描电子显微镜分析研究了430、316、304不锈钢试样在高温密封的单质硫及硫化钠环境中的腐蚀规律,并在316不锈钢表面电镀Mn、Ni镀层探究其防护效果。结果表明,在高温密封的单质硫、硫化钠环境中不锈钢材料腐蚀速率的规律为:v(430不锈钢)>v(304不锈钢)>v(316不锈钢),且在硫化钠环境中的腐蚀更严重。镀镍对不锈钢的耐蚀性能没有提高,镀锰可以提高316不锈钢的耐高温硫腐蚀性能,腐蚀速率降为0.0166 mm/a。
The corrosion of 430,316,304 stainless steel in sulfur and sodium sulfide environments in high temperature was discussed by weight gain,XRD,SEM techniques. Mn or Ni coating was electroplated to study the protective effect on the surface of 316 stainless steel. In sealed sulfur and sodium sulfide environments at high temperature,the corrosion rule of the stainless steel was v（ 430） v（ 304） v（ 316）,and the corrosion rate was higher in the environment of sodium sulfide. The corrosion rate of 316 stainless steel with nickel coating was not decreased,but the corrosion resistance of stainless steel was improved by the deposition of manganese. The corrosion rate was decreased to 0. 016 6 mm / a.
