Results indicate the biofilm is uniformly aerobic and does not contain elevated levels of cathodic depolarizers. Galvanostatic measurements of coupon capacitance reveal a strong correlation between capacitace and Ecorr as the latter increases during microbial colonization. Fe2O3 content occurs for stainless steel samples that develop ennobled potential.
Results suggest an ennoblement mechanism involving modifications of the metal-oxide surface.
A new interpretation of cathodic polarization behavior for ennobled stainless steel is given based on proposed changes in cathodic reaction rates that occur on the microbially modified oxide surface during polarization.
