硫酸盐还原菌（SRB）对907钢腐蚀的影响 钢进行了调查。结果表明， 腐蚀产物、腐蚀速率和腐蚀类型由于 硫酸盐还原菌在907钢表面的附着和生物膜的形成。 与无菌培养基中以氧化亚铁为主的情况不同， 腐蚀产物中，硫化亚铁是含SRB的腐蚀产物中的重要组分， 介质同时，硫酸盐还原菌对907钢的腐蚀有促进作用， 速率取决于他们的代谢活动，增加，稳定， 分别在指数生长期、死亡期和残留期下降。 腐蚀类型由均匀腐蚀向局部腐蚀转变 介绍了硫酸盐还原菌（SRB）的引入对腐蚀的影响，并分析了SRB的发展过程 基于线束电极的电流分布图。在无菌培养基中， 最大电流密度随浸泡时间的延长而减小， 晚期无明显的阳极电流峰，而含SRB的 介质中，阴极面积与阳极面积之比高， 指数生长期，死亡时逐渐形成稳定的阳极位点， 残余相，这促进了局部腐蚀的发展。
The effect of sulfate-reducing bacteria (SRB) on the corrosion of 907 steel was investigated. Results demonstrated that the chemical composition of corrosion products, the corrosion rate, and corrosion type were altered due to the adherence of SRB and the subsequent formation of biofilm on the 907 steel surface. Different from the case in sterile medium that ferrous oxides predominated in the corrosion products, ferrous sulfide was an important component in SRB-containing medium. Meanwhile, corrosion of 907 steel was enhanced by SRB, and the corrosion rate was dependent on their metabolic activity, which increased, stabilized, and decreased in the exponential growth, death, and residual phases, respectively. Furthermore, the corrosion type was changed from uniform corrosion to localized corrosion with the introduction of SRB, and the development process was analyzed based on the current distribution map of wire beam electrodes. In sterile medium, the maximum current density decreased with the immersion time extended, and there were no significant anodic current peaks in the late period, while in SRB-containing medium, the ratio between cathodic areas and anodic areas was high in the exponential growth phase, and stable anodic sites formed gradually in death and residual phases, which facilitated the development of localized corrosion.
