就海水体系中硫酸盐还原菌 (SRB)对铝合金的腐蚀进行了研究 ,使用扫描电镜以及表面能谱分析方法研究了微生物对铝合金腐蚀的影响。结果表明 :硫酸盐还原菌的代谢产物能够破坏铝合金钝化膜 ,参与腐蚀反应并加速腐蚀的进行。
The corrosion of aluminum alloy by sulfate reducing bacteria (SRB) in seawater system was studied. The effects of microorganisms on the corrosion of aluminum alloy were studied by scanning electron microscopy and surface energy spectrum analysis. The results showed that the metabolites of sulfate-reducing bacteria could destroy the aluminum alloy passivation film, participate in the corrosion reaction and accelerate the corrosion.
