Abstract
Effects of sulfate-reducing bacteria(SRB) activities on the acceleration of corrosion of carbon steel were studied by EIS and the role of sulfur-containing metabolites by SRB in enhancing the anodic active dissolution of carbon steel was investigated by steady-state polarization technique. The results show that sulfur-containing metabolites in the form of adsorbed sulfur on iron enhance the anodic active dissolution of carbon steel. The adsorbed sulfur raises the energy of surface iron atoms of carbon steel, reduces the necessary activation energy for their dissolution from metal matrix and thus enhancing the anodic active dissolution.
