Abstract
A method of monitoring the rate of corrosion of a cathodically protected system, comprising superimposing a sinusoidal voltage on a cathodic protection voltage imposed on a portion of the system, measuring an anodic dissolution current in response to the superimposed voltage, and calculating the corrosion rate from the anodic dissolution current at the cathodic protection voltage potential.
