含硫酸盐还原菌污染土壤中Q235钢的宏电池腐蚀研究
Macro Cell Corrosion of Q235 Steel in SRB Contaminated Soils
摘 要
用建立的宏观腐蚀电池模拟试验装置, 通过宏电池电流、开路电位、电化学阻抗、扫描电镜等方法, 研究了在硫酸盐还原菌接菌和无菌的污染土壤中, 试验时间和宏电池阴阳极面积比对宏电池腐蚀的影响。结果表明, 由于硫酸盐还原菌的作用, 宏电池的阴阳极关系在试验开始的几天里发生了反转; 宏电池的阴阳极面积比越大, 越有利于宏电池腐蚀的进行。

Abstract
Macro cell simulation test device was prepared to study the influence of testing time and area ratio of anode and cathode on macro cell corrosion when RSB existed in contaminated soils. The influence was evaluated by macro cell corrosion current, open circuit potential, EIS and scanning electron microscopy.
