What steps can be taken to prevent the damage caused due to corrosion of iron?

Steps that can be taken to prevent damage caused due to corrosion of Metals are :
1. Barrier protection method: A barrier film is introduced between iron and atmospheric oxygen and moisture. Barrier protection can be achieved
  • By painting the surface
  • By coating the surface with a thin film of oil or grease.
  • By electroplating iron with some non-corrosive metal such as nickel, chromium, copper, etc.

2. Sacrificial protection: The surface of iron is covered with a layer of more active metal like zinc. This active metal undergoes oxidation in preference to iron and hence, prevents the rusting of iron.
Zinc metal is generally used for protecting iron and the process is called galvanization.
