The Molecular Basis of Humic Acid Reduction and its Role in Microbiologically Influenced Corrosion (MIC)

Abstract

Based on the experimental values of the corrosion potential and the polarization resistance it was demonstrated that iron respiration can protect steel from corrosion. A new electrochemical model that explains the mechanism of this process has been developed. This mechanism is based on the assumption that iron-reducing biofilms reduce the rates of both the oxygen reduction and the metal dissolution reactions that are involved in the corrosion of iron and mild steel.
