Corrosion prevents corrosion : Some metals like zinc are used as sacrificial anodes to prevent corrosion to other metal.
Galvanic corrosion : The principle on which primary batteries work. In which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte.
