| 摘 要： | 通过测量极化曲线和阻抗谱,研究了Q235钢正火区在SRB和V.natriegens共同作用下的腐蚀行为。研究表明,正火区的腐蚀程度,单一菌溶液中,SRB大于V.natriegens,混合菌溶液大于单一菌；混合菌溶液中SRB和V.natriegens表现出协同作用,加速试样的腐蚀。

| Abstract: | The corrosion behavior of the Q235 steel normalized zone exposed in the mixed bacteria medium (SRB and V.natriegens) through different culture cycle was investigated by polarization curves and electrochemical impedance spectra. It was found that the extent of corrosion in SRB medium was stronger than in V.natriegens medium, while that in mixed bacteria medium was stronger than in single bacterium medium; The sample corrosion was accelerated as a result of the synergism displayed by the mixed bacteria. |
