Will prevent damage due to corrosion and oxidation

The process of coating a metal surface with another metal that is more likely to be oxidized is referred to as sacrificial coating. The corrosion-prone iron alloy steel is commonly coated with zinc, a more active metal, in a process known as galvanizing. Corrosion of the sacrificial zinc results in its oxidation; the iron is reduced, which renders it cathodic and inhibits its corrosion.
