journalArticle Qian Hongchang Liu Shangyu Wang Pei Huang Ye Lou Yuntian Huang Luyao Jiang Chengying Zhang Dawei Electrochemical impedance spectroscopy (EIS) Microbiologically influenced corrosion Stainless steel Investigation of microbiologically influenced corrosion of 304 stainless steel by aerobic thermoacidophilic archaeon Metallosphaera cuprina In this study, the influence of thermoacidophilic archaeon Metallosphaera cuprina on the corrosion of 304 stainless steel was investigated. 304 stainless steel in M. cuprina-inoculated culture medium exhibited more marked pitting corrosion behavior than that seen in sterile culture medium. After 14 days, the average pit depth under M. cuprina biofilms was nearly twice as great as that in sterile culture medium. Electrochemical measurements also showed that 304 stainless steel had lower charge transfer resistance and smaller pitting potential after 14 days of exposure in inoculated culture medium. The ferrous ion oxidation ability of M. cuprina biofilms can cause a change in the composition of passive films and accelerate the anodic dissolution of the steel substrate, to promote the pitting corrosion process at 304 stainless steel. 107635 August 17, 2020 en http://www.sciencedirect.com/science/article/pii/S156753942030089X 2020-08-26 09:59:28 ScienceDirect Bioelectrochemistry Bioelectrochemistry DOI 10.1016/j.bioelechem.2020.107635 ISSN 1567-5394
