Methods of preventing corrosion

Explanation

Alloying: The metals can be alloyed to prevent the process of corrosion. E.g: Stainless Steel. (in)
Surface Coating: It involves application of a protective coating over the metal. It is the following types: (a) Galvanization: It is the process of coating zinc on iron sheets by using electric current () Electroplating: It is the method of coating one metal over another metal by passing electric current.
(c) Anodizing: It is an electrochemical process that converts the metal surface into an decorative, durable and corrosion resistant. Aluminium is widely used for anodizin process.
(d) Cathodic Protection: It is the method of controlling corrosion of a metal surfac protected is coated with the metal which is easily corrodible. The easily corrodible metal is called Sacrificial metal to act as anode ensuring cathodic protection.
