Frequency and Time Resolved Measurements at Rotating Ring‐Disk Electrodes for Studying Localized Corrosion

Abstract

By conferring frequency and time resolution on the rotating ring‐disk electrode technique, original information can be obtained on the mechanism of corrosion processes involving the formation of intermediate, passive, or corrosion product layers. The methodology that allows the measurement of the actual flux of chemical species generated by a localized corrosion site is described which takes into account the usual parameters of the RRDE and the location of the active spot on the disk surface. Application to pitting corrosion of iron by Cl− in sulfuric and phosphoric acids reveals important features of the early transient events in the pit life.
