研究了铜绿假单胞菌对不同 α 组分的 2205 双相不锈钢的腐蚀。结果发现，P.铜绿假单胞菌加速点蚀，α分数为53.8%时具有最好的耐腐蚀性，这与最高的电阻、最少的钝化膜缺陷和最少的生物膜有关。由于细菌在相边界的优先附着及其向α相的扩展，在生物介质中的相边界或α相处出现凹坑。铜绿保持 α 相和 γ 相之间的高电压差异，以促进 α 相的阳极溶解。数据可用性声明重现这些发现所需的原始/处理数据目前无法共享，因为这些数据与正在进行的研究相关。
Corrosion of 2205 duplex stainless steel with different α fractions affected by Pseudomonasaeruginosawas investigated. It was found thatP. aeruginosaaccelerated pitting corrosion, and an α fraction of 53.8% gave the best corrosion resistance, which was related to the highest resistance, and fewest defects of passive films, and least biofilms. Pits appeared at phase boundaries or α phase in biotic media, due to the preferential attachment of bacteria at phase boundaries and their expansion towards α phase.P. aeruginosakept high volta differences between α and γ phases to promote the anodic dissolution of α phase.Data availability statementThe raw/processed data required to reproduce these findings cannot be shared at this time as the data are related to an ongoing study.
