Abstract:
A method to detect and assess microorganism influenced corrosion includes measuring current flow between a test electrode and a control electrode in a split chamber zero resistance ammeter apparatus and calculating a predictive difference in mass loss between the test electrode and the control electrode based on that current over time; and measuring the resistance, Rpit, of a surface of the subject metal to assess pitting corrosion using an electrochemical impedance spectroscopy apparatus.
