The increasing utilization of titanium alloys in marine environments makes their microbiologically influenced corrosion study a timely matter. This work demonstrated that the corrosion of Ti-6Al-4 V alloy was accelerated by a marine bacterium Shewanella algae (S. algae) in 2216E medium with different Cl⁻ level. Various electrochemical, pitting morphology and passive film analyses demonstrated that S. algae weakened the passive film, which made Cl⁻ more aggressive. The synergy of those two factors caused considerable corrosion acceleration of the titanium alloy, leading to a maximum pit depth of 3.2 μm and corrosion current density of 26.5 nA cm⁻² in 2216E medium with 3.50% (w/w) Cl⁻.

钛合金在海洋环境中的利用率不断提高，使它们受到微生物影响的腐蚀研究成为当务之急。这项工作表明，的Ti-6AL-4V的合金的腐蚀是由海洋细菌加速海藻希瓦氏菌（S.藻类）在具有不同氯2216E介质^-水平。各种电化学点蚀形态和钝化膜分析表明，S.藻类削弱了钝化膜，这使氯^-更具侵略性。这两个因素的协同作用导致钛合金显着腐蚀加速，在含3.50％（w / w）Cl的2216E介质中，最大凹坑深度为3.2μm，腐蚀电流密度为26.5 nA cm ^-2。^-。
