| 摘要 | The electrochemical corrosion behaviour of Q235 steels in 3.5 wt.% NaCl solutions with sulphide and extracellular polymeric substances (EPS), the two main metabolites of sulphate-reducing bacteria, was separately investigated through potentiodynamic polarisation and electrochemical impedance spectroscopy. Either sulphide or EPS increased the anodic current density by nearly one order of magnitude and negatively shifted the corrosion potential. The effects of EPS at the initial stage of corrosion may be ascribed to the Fe2+-complexing capability and the quickly adsorbed film. Moreover, the feeble protective effect of EPS after 16 d of immersion was observed through scanning electron microscopy. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved. |
