摘要:

采用失重法、SEM、EDS微观分析方法和电化学阻抗技术研究了X70钢在有/无SRB的侵蚀性土壤模拟溶液中的腐蚀行为。结果表明，在无菌介质中，X70钢表面生成不具有保护性的腐蚀产物，其腐蚀速率随浸泡时间的延长而增大；在有菌介质中，钢表面形成致密的生物膜，对界面传质有一定的阻碍作用，从而减轻X70钢的腐蚀。腐蚀产物的吸附及S含量随浸泡时间的延长而增加，使得腐蚀产物膜疏松易脱落，促进了基体的腐蚀。无菌介质中腐蚀产物内层的稳定性与腐蚀产物的沉积及分布有关；而在有菌介质中，多孔的胞外聚合物对活化过程中的质量传输过程有一定阻碍作用。

Abstract：The corrosion behavior of X70 steel was studied in a simulated soil solution with and without sulfate-reducing bacteria (SRB) by means of weight-loss measurement, SEM-EDS analysis and electrochemical impedance spectroscopy (EIS). The results showed that the corrosion rate increased with time in the solution without SRB, while the corrosion product film was loose and non-protective. In the solution with SRB, however, a compact and homogeneous biofilm formed on the steel surface, which could suppress the mass transfer so that to mitigate the steel corrosion, whilst the corrosion product film became loose and apt to spall because of the increasing amount of absorbed substance and sulfide in the corrosion product with time, in consequence the corrosion of the steel substrate was further promoted. The stability of the inner portion of the corrosion product film was related to the distribution of deposits on the steel in the solution without SRB. The porous extracellular polymeric substances (EPS) formed on the steel in the solution with SRB played a role in barrier action to the mass transfer during the activated process.
