A new potentiostatic electrochemical noise (P-ECN) technique was recently developed to explore further improvement in corrosion monitoring methods. This technique has the ability to enhance monitoring of both general and localized corrosion. P-ECN uses a standard one-working, three-electrode electrochemical cell where both current noise and potential noise are measured at the same working electrode at open-circuit potential. The current and potential noise responses to switching between the open-circuit and potentiostatic mode were investigated.
