摘要: Various corrosion media were prepared by dual-cells experimental setup, including fresh sterilized culture medium, medium with sulfate-reducing bacteria (SRB), and containing only SRB metabolites. Corrosion exposure tests of Q235 carbon steel conducted in these media, effects on the behavior studied electrochemical methods surface analyses. As results, was uniformly corroded a mode active dissolution; SRB, protected iron sulfides layer to some extent early stage exposure, but severely localized subsequently occurred resulting from breakdown presence biofilm; while metabolites, well over whole period, suggesting that uniform stable formed this medium.
