Abstract
A technique for the determination of the rate of corrosion is describe d based on the harmonic analysis of the current of the electrode pertu rbed with relatively small amplitude undistorted sinusoidal alternatin g voltage. The measurement carried out in the vicinity of the corrosio n potential permits the determination of both the corrosion current de nsity and the Tafel slopes. The technique is illustrated using a study of the corrosion of various types of iron electrodes in acidic and ne utral media.
