Analysis of carbon steels affected by bacteria using electrochemical impedance and direct current techniques
(1988) In Corrosion: Journal of science and engineering 44(12). p.869-874- Abstract
The failure of metal structures in contact with natural, untreated waters is frequently ascribed to bacterial corrosion. This study compares the corrosive effects of Vibrio natriegens (V. natriegens) when in batch and continuous flow culture. Evidence is presented for enhanced corrosion of carbon steel resulting from aerobic culture of V. natriegens with two sulfate-reducing bacteria (SRB). The corrosion processes are quantified and, to some degree, described by nondestructive electrochemical impedance and direct current (DC) polarization techniques. The V. natriegens/SRB co-culture induces a faster corrosion rate of carbon steel than V. natriegens alone or under sterile conditions. Batch culture permitted a faster corrosion rate than... (More)
The failure of metal structures in contact with natural, untreated waters is frequently ascribed to bacterial corrosion. This study compares the corrosive effects of Vibrio natriegens (V. natriegens) when in batch and continuous flow culture. Evidence is presented for enhanced corrosion of carbon steel resulting from aerobic culture of V. natriegens with two sulfate-reducing bacteria (SRB). The corrosion processes are quantified and, to some degree, described by nondestructive electrochemical impedance and direct current (DC) polarization techniques. The V. natriegens/SRB co-culture induces a faster corrosion rate of carbon steel than V. natriegens alone or under sterile conditions. Batch culture permitted a faster corrosion rate than continuous flow systems. When continuous flow conditions were allowed to lapse into stagnation (batch culture), however, the highest corrosion rate was observed. This confirms practical experience in which metal failure caused by bacteria is often correlated with stagnation.
