Complex design requirements can make it necessary to combine different metallic materials within the same component. Also, chance combinations can often be found, governed only by the availability of, for instance, fasteners or shims. In certain circumstances, such mixed-material designs can lead to corrosion in one of the partner materials. This phenomenon includes galvanic corrosion, in which two different metals form a galvanic couple.
The present publication describes the principles of galvanic corrosion and the main parameters that allow designers to estimate corrosion risk.
