Effect of sulfate-reduced bacteria on corrosion and electrochemical behaviors of LY6 Al alloy

  • The open circuit potential, potentiodynamic scanning polarization and electrochemical impedance spectroscopy (EIS) were employed to analyze the corrosion behaviors of LY6 Al alloy in solutions with and without sulfate reduced bacteria(SRB).It was showed that SRB accelerated the corrosion rate of LY6 Al alloy, and the corrosion rate of dynamic test sample was larger than that of static test sample. The open circuit potential shifted negatively with the time. The shifted values were 0.26V(SCE)and 0.16V (SCE) in solution with and without SRB,respectively. The range of apparent pitting potential obtained from anodic polarization was -0.6~0.2V(SCE). It was found that polarization resistance decreased with the time based on EIS results.
