Corrosion - Wikipedia

Galvanic corrosion occurs when two different metals have physical or electrical contact with each other and are immersed in a common electrolyte, or when the same metal is exposed to electrolyte with different concentrations.In a galvanic couple, the more active metal (the anode) corrodes at an accelerated rate and the more noble metal (the hode) corrodes at a slower rate.
