| 摘 要： | 根据碳钢在分别添加了Cl-、SO42-和Cl- SO42-的土壤中接菌与灭菌两种条件时的电化学阻抗谱特征,研究了硫酸盐还原菌(SRB)对碳钢腐蚀的影响.试验结果表明,三种盐分土壤中SRB均加速了碳钢的腐蚀速度.当Cl-灭菌土壤中添加SO42-时,26天后碳钢腐蚀速度显著增加;当SO42-灭菌土壤中添加Cl-时,碳钢腐蚀速度减小.

| Abstract: | The EIS characteristics of carbon steel in Cl~-,SO_4~(2-)and Cl~-+SO_4~(2-)soils with or without SRB were summarized.SRB could promote the corrosion rate of carbon steel in three kinds of soil.When SO_4~(2-)was added to the soil containing Cl~-,the corrosion rate of carbon steel increased greatly in the soil without SRB after 26 days.On the contrary,when Cl~- was added to the soils contained SO_4~(2-),the corrosion rate of carbon steel decreased obviously in the soil without SRB. |
