Diagnosing, Measuring and Monitoring Microbiologically Influenced Corrosion (MIC)

Abstract

The relationship between microorganisms and corrosion is both predictable and complex. In aquatic environments and under some atmospheric conditions, microorganisms settle on surfaces and alter the surface chemistry controlling the rates of corrosion or shifting the mechanism for corrosion. The result is corrosion where none could be anticipated based on the composition of the bulk medium, e.g., low-chloride waters, and rates that are exceptionally last. Under some circumstances microorganisms can also inhibit corrosion. The influence of microorganisms on corrosion depends, not only on the presence and activities of the microorganisms, but also the nature of the metal/alloy and the specific environment in which the organisms are growing, e.g., aerobic vs anaerobic, ratio of aggressive anions to non-aggressive anions and nutrients.
