GALVANIC PROTECTION

The selective use of galvanic corrosion to protect one metal from deterioration by connecting it to
another, more active (electrically negative), sacrificial metal. Both metals must be in contact with
each other in the same body of an electrolyte. Zinc, magnesium, or aluminum can be used as
sacrificial metals for the galvanic protection of steel
