Abstract
A process to detect damage to a bonded composite repair of metal equipment. The process includes the steps of monitoring electrical resistance in a direct current impressed current cathodic protection circuit having a power supply and an anode in electrical communication with metal equipment having a bonded composite repair thereto. Deterioration of the bonded composite repair is detected based on a change in the electrical resistance of the circuit.
