摘要
研究了温度为２５～１００℃时对硫酸盐还原菌生长的影响，并通过２５～６０℃的腐蚀试验，结合腐蚀产物Ｘ光衍射分析表明，硫酸盐还原菌对钢铁腐蚀的促进或减缓作用与其表面腐蚀产物硫化物有关。若生成Ｆｅ９Ｓ８，硫酸盐还原菌去极化作用不断进行而加速钢铁腐蚀；若生成ＦｅＳ，形成较致密的保护膜，使硫酸盐还原菌去极化作用受阻，腐蚀减缓。
The influence of temperature on the growing of sulfate reducing bacteria(SRB)is studied when the temperature is at 20-100℃.The results of corrosion test and X-ray diffraction analysis of corrosion product at 20-60℃ showed that the promotion or inhibition of steel corrosion by SRB was decided by the type of crystal of the corrosion product on the steel surface. SRB increases the corrosion while the product is Fe9S8,and inhibits the corrosion while it is FeS.
