| 摘 要： | 利用间歇式方法培养硫酸盐还原菌和需钠弧菌,并采用自腐蚀电位、极化曲线、冷场扫描电镜观察等方法,研究了白铜在海洋优势菌种硫酸盐还原菌和需钠弧菌共同作用下的腐蚀电化学行为。结果表明:海洋微生物的存在加速了白铜的腐蚀进程;硫酸盐还原菌在混合菌种培养基中对白铜的腐蚀起主导作用;硫酸盐还原菌和需钠弧菌共同作用下基体表面团聚现象严重,倾向于发生点蚀;微生物对基体腐蚀影响严重程度依次为:硫酸盐还原菌、混合菌、需钠弧菌、无菌。

| Abstract: | The method of intermittence reaction is used to foster sulfate-reducing bacteria(SRB) and vibrio natriegens(V.natriegens).And polarization curves,corrosion potential,scanning electron microscopy(SEM) are carried out to research the corrosion behavior of B10 in the combined action of SRB and V.natriegens.The results show that the marine microorganisms accelerated corrosion process of B10;SRB in the mixed microbe medium plays a leading role;the combined action of SRB and V.natriegens influences matrix surface reunion phenomenon seriously and is prone to pitting corrosion;microbial corrosion affect severity of matrix is as follows: SRB,mixed bacteria,V.natriegens,sterile. |
