摘要 利用微生物分析、交流阻抗测试技术、扫描电镜及表面能谱等方法 ,在室内模拟条件下研究了海底土中硫酸盐还原菌对锌腐蚀的影响 ,以及在以接菌及灭菌的海底土构成的宏电池腐蚀中锌的腐蚀行为。180d的试验结果表明 :海底土中硫酸盐还原菌增强锌的腐蚀 ,锌在接菌泥中的平均腐蚀速率及点蚀深度均大于在灭菌泥中的平均腐蚀速率及点饰深度 ,平均腐蚀速率相差 7.0倍 ,点蚀速率相差 15 .0倍以上。在接菌和灭菌海底土构成宏电池时 ,接菌海底土中锌作为阳极 ,腐蚀速率比自然腐蚀状态下有所增大 ,加速率为 12 .7% ,而在灭菌海底土中锌作为阴极 ,腐蚀速率比自然腐蚀状态下有所减小。 The effects of Sulfate Reducing Bacteria(SRB) on corrosion of zinc in marine sediment and macrocell corrosion of Zn in marine sediment with or without SRB were studied by using bacterial analyses, electrochemical impedance spectroscopy, scanning electron microscopy (SEM) and EDAX. The results show the pitting rate of zinc in marine sediment with SRB is 15.0 times of those in marine sediment without SRB. The corrosion of samples in the marine sediment with SRB is accelerated as the anode of macrocell.
