Abstract
A coating system for ferrous and nonferrous metal substrates that provides cathodic protection from corrosion by coating with inherently conductive polymers and sacrificial anodic metal particles. The coating system is formed by a process that includes premixing of the inherently conductive polymer with the anodic metal particles to form an inherently conductive polymer/metal particle complex.
