Galvanic corrosion - Wikipedia
Galvanic corrosion (also called bimetallic corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte.A similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power portable devices.
