Microbiologically influenced corrosion inhibition (MICI) of aluminum alloy (AA) 5083 by three representative Vibrio species were evaluated using electrochemical, surface analysis and surface characterization techniques. Interestingly, all the bacteria exhibited profound inhibitory effect on the corrosion of AA5083 in the chloride-containing culture medium. The MICI mechanism of tested Vibrio species is that mature biofilms acted as a diffusion barrier to prevent the penetration of corrosive chloride and consumed up the diffused oxygen by their aerobic respiration. Thus, the biofilm increased the passive range and inhibited the localized attack on the AA5083 surfaces.

使用电化学，表面分析和表面表征技术评估了三种代表性弧菌对铝合金（AA）5083的微生物影响的腐蚀抑制（MICI）。有趣的是，所有细菌均对含氯培养基中AA5083的腐蚀表现出深远的抑制作用。被测弧菌物种的MICI机制是，成熟的生物膜充当扩散屏障，以防止腐蚀性氯化物渗透，并通过需氧呼吸消耗掉扩散的氧气。因此，生物膜增加了被动范围，并抑制了对AA5083表面的局部攻击。
