Multi-Metallic Galvanic Corrosion

Abstract

In the past, there have been a number of material failures in the Army's equipment. Many of these failures have been caused by some form of corrosion. One type of corrosion involved is galvanic corrosion. This happens when dissimilar metals come in contact in an electrolyte. The electrolyte could be a marine or even a humid environment. When this occurs, the less noble metal (anode) corrodes in order to protect the more noble metal (cathode). By exposing multi-metallic galvanic couples of high strength materials in aggressive environments, the number of failures in bridges and other military equipment could be reduced.
