What Does Corrosion Mean? Galvanic corrosion is an electrochemical process in which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte. Copper is considered to be a noble metal, and as a result is able to resist attack by oxygen.The metal is basically immune to corrosion due to a naturally occurring protective film known as a patina that forms on the metal's surface. This capability is being put to use on several major projects around the world where the client has entrusted BAC with the supply of Transformer Bimetallic corrosion is a purely electrochemical reaction driven by the difference in electrode potentials between the two metals.
