Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water.
Prevention method of rusting
- Many different types of coatings can be applied to the surface of the exposed metal in order to prevent corrosion. Common examples of coatings that prevent corrosion include paints, wax tapes, and varnish.
- Galvanization is the process of applying a protective layer of zinc on a metal. It is a very common method of preventing the rusting of iron.
- Providing the metals with an electric charge can help inhibit the electrochemical reactions that lead to rusting.
