Studies of the Corrosion Behavior of Stainless Steels in Chloride Solutions in the Presence of Sulfate Reducing Bacteria

摘要: Experimental studies on the corrosion of Types 304 and 304L stainless steels (SS) in 0.5M chloride solutions with presence sulfate reducing bacteria (SRB) a slime former were conducted. Coupled multielectrode sensors electrochemical polarization techniques employed this study. No significant difference between repassivation potentials was observed without SRB. The SS electrodes both SRB-containing SRB-free coupled to large cathodes separate aerated cell their increased stepwise from –0.26 –0.04 VSCE. pitting after three-month exposure. Anodic measurements using platinum electrode SRBcontaining solution suggest that anodic peak probably due oxidation species attached surface by It concluded use current density characterize microbially induced metals might lead wrong interpretation.
