Test methods for microbiologically influenced corrosion (MIC) in marine environments

Electrochemical techniques such as measurements of corrosion and redox potentials, polarization curves, polarization resistance, electrochemical impedance and electrochemical noise have been used to evaluate the impact of marine microorganisms on corrosion processes. Surface analytical techniques including microbiological culturing, scanning electron microscopy, microprobes and microelectrodes have been used to characterize metal surfaces after exposure to marine waters. A combination of electrochemical, surface analytical and microbiological techniques is the most promising approach for determining mechanisms of MIC
