ABSTRACT:
A system for preventing corrosion of a surface of a metal structure in contact with a corrosive environment comprising (a) a conductive zinc silicate coating in conductive contact with at least part of the surface, wherein the conductive zinc silicate coating forms an interfacial layer between the surface and the corrosive environment; and (b) means for imparting a net negative bias to the metal structure, wherein the means is a power supply means having (1) a first capacitor having a positive plate and a negative plate, wherein the negative plate is grounded to earth and the positive plate is conductively coupled to at least one emitter, and (2) one or more storage cells conductively coupled in parallel to the first capacitor, wherein the one or more storage cells have a positive terminal and a negative terminal, wherein the negative terminal is directly coupled to said metal structure and said positive terminal coupled to the metal structure, at a position remote from the negative terminal, by way of a second capacitor; and a method of preventing corrosion using the system.
