通过腐蚀形貌分析、腐蚀产物分析和电化学测试多种分析测试手段，研究了干湿交替循环下低碳钢在H2S溶液中的腐蚀行为。综合分析结果表明腐蚀初期产物较少，腐蚀速率与循环次数成正比；腐蚀后期，腐蚀产物较多，形成一层保护膜，阻碍腐蚀过程的进行，腐蚀速率与循环次数成反比。FeS的生成可能是腐蚀速率出现转折的一个因素。
Corrosion behavior of mild steel in the condition of H2S in wet/dry cycles was studied by corrosion analysis, corrosion product and morphology analysis and electrochemical measurement. The results show that the initial corrosion products are less, and corrosion rate is proportional to cycle times; with accumulation of more corrosion product, which possibly acts as corrosion barrier, corrosion rate is inversely proportional to cycle times based on comprehensive analysis. The formation of FeS may be a factor responsible for a turning point of corrosion rate.
