Opposites Attract: A Primer on Galvanic Corrosion of Dissimilar Metals
Engineers and architects often encounter conditions where dissimilar metals are in contact. When these situations arise, it is appropriate to consider the corrosion susceptibility of the materials. Although the term corrosion can be broadly applied to any degradation of a metal and can have a variety of causes, this article will discuss the main drivers of galvanic corrosion, which occurs between two dissimilar metals, and offer some strategies to help engineers assess and mitigate its effect in structural applications.
