Microbiologically influenced corrosion (MIC) has caused great losses to many industries. This paper aimed to study the corrosion behavior of on X65 steel. The corrosion behavior of on X65 steel under aerobic and anaerobic conditions was studied by scanning electron microscopy, energy dispersive spectrometer and electrochemical analysis techniques. The results showed that the corrosion rate of X65 steel in bacterial environment is higher than that in sterile environment. In anaerobic environment, the corrosion of is mainly secreted acidic metabolites, and alkaline substances are corroded in aerobic environment. In general, the corrosion of X65 steel by in aerobic environment is more serious than that in anaerobic environment.
微生物影响下的腐蚀(MIC)给许多行业造成了巨大损失。本文旨在研究[未提及具体物质]对X65钢的腐蚀行为。通过扫描电子显微镜、能谱仪和电化学分析技术研究了[未提及具体物质]在有氧和无氧条件下对X65钢的腐蚀行为。结果表明,X65钢在细菌环境中的腐蚀速率高于无菌环境。在厌氧环境中,[未提及具体物质]的腐蚀主要是分泌酸性代谢产物,而在有氧环境中碱性物质被腐蚀。总体而言,[未提及具体物质]在有氧环境中对X65钢的腐蚀比在厌氧环境中更严重。
