Abstract
A graphene composite coating on a metal surface with excellent corrosion resistance by electrophoretic or electrolytic deposition has been obtained. The composite coating was shown to significantly increase the resistance of the metal surface to electrochemical degradation. The graphene coating significantly reduces cathodic current, which is an indicator of the rate of corrosion at the interface between the cathodic material and the anodic material.
