Corrosion Behaviors of B10 under the Combination Action of Sulfate-Reducing Bacteria and V.Natriegens

Abstract:

Polarization curves, corrosion potential, scanning electron microscopy (SEM) were adopted in order to investigate the corrosion behaviors of B10 under the combination action of anaerobic SRB and facultative anaerobic V.natriegens. The characteristics and mechanisms of microbial corrosion action in sea water were analyzed in this paper. The results show that the existence of marine microorganisms accelerates the corrosion process of B10; SRB in the mixed microbe medium plays a leading role; the combined action of SRB and V.natriegens influences the matrix surface reunion phenomenon seriously and prone to pitting corrosion. Furthermore, this investigation indicates that the affectability of microbial corrosion of the base metal can be shown as follows: SRB > Mixed bacteria > V.natriegens > Sterile.
