Galvanic Corrosion on Automobiles

Source

Automobile manufacturers utilize a variety of metals to build a product that meets numerous functional and cosmetic demands. Since the auto environment is highly corrosive, they must consequently deal with galvanic corrosion problems. This paper describes some of the galvanic couples on automobiles, such as trim on painted auto-body steel, dissimilar metal fasteners, electroplated bumpers, galvanized steel, and dissimilar cooling system components. The resulting problems and mitigative measures for controlling galvanic corrosion are presented.
