The effect of NRB on the corrosion behavior of X80 pipeline steel in the soil extract solution of Shenyang was studied using polarization curve, electrochemical impedance spectroscopy, weight-loss tests and scanning electron microscope. The results show that NRB accelerates the corrosion rate of steel and promotes the formation of pitting holes on the surface of steel. XPS results show that the types of corrosion products are unchanged. Moreover, electrochemical measurements can effectively evaluate the corrosion behavior of pipeline steel affected by NRB in real time. The data in this work support that NRB can be responsible for pipeline perforation and leakage.

硝酸盐还原菌对X80管线钢在沉阳土壤提取液中腐蚀行为的影响

利用极化曲线，电化学阻抗谱，失重测试和扫描电子显微镜研究了NRB对X80管线钢在沉阳土壤提取液中腐蚀行为的影响。结果表明，NRB促进了钢的腐蚀速率并促进了钢表面点蚀孔的形成。XPS结果表明，腐蚀产物的类型没有变化。而且，电化学测量可以有效地实时评估受NRB影响的管线钢的腐蚀行为。这项工作中的数据支持NRB负责管道穿孔和泄漏。
