Investigation on Fe3Al Corrosion Behavior in Simulating Marine Biofilm Environment


Article Preview

In terms with the natural structure and property of microbe film, microbe film was simulated by Calcium Alginate gel Acetic acid, manganese dioxide, sodium sulfide were added separately into sodium chloride solution to simulate different bacteria culture systems. The corrosion behavior of Fe3Al was characterized based on the analysis of open circle potential, polarization curves, and electrochemical impedance. The corrosion potential of simulating SRB was 0.6V negative-moved in comparison with that of the other two bacteria. The results indicate that Fe3Al electrodes were much easier eroded by SRB environment.
