摘要
分析海水模拟溶液中硫酸盐还原菌(SRB)对Q235钢的腐蚀情况,研究不同浓度氯离子对微生物腐蚀的影响。结果表明:海水模拟溶液中微生物的存在促进了Q235钢的腐蚀;腐蚀速率随氯离子浓度的增加而减小,氯离子对Q235钢的微生物腐蚀具有抑制作用。
Analysis the corrosion characteristics of Sulfate Reducing Bacteria(SRB)of Q235steel in the simulated seawater solution,research the effects of different concentrations of chloride ion with the same concentration of SRB on microbial corrosion.The results showed that:(1)The corrosion rate of Q235steel was accelerated by the effect of SRB.(2)With the same concentration of SRB,the corrosion rate of Q235steel reduced as the increase of the concentration of chloride ion,which means that the exist of the chloride ion can restrain the corrosion.
