Influence of the α fraction on 2205 duplex stainless steel corrosion affected by Pseudomonas aeruginosa
Source abstract
Abstract
Abstract Corrosion of 2205 duplex stainless steel with different α fractions affected by Pseudomonas aeruginosa was investigated. It was found that P. aeruginosa accelerated 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. aeruginosa kept high volta differences between α and γ phases to promote the anodic dissolution of α phase. Data availability statement The raw/processed data required to reproduce these findings cannot be shared at this time as the data are related to an ongoing study.
