1.	How is metal corrosion prevented?
Answer» SOLUTION :Methods of preventing corrosion : E.g : Stainless Steel 2. Surface Coating : It involves application of a protective coating over the metal. It is of the following types: (a) GALVANIZATION : It is the process of coating zinc on iron sheets by using electric current. (b) Electroplating : It is a 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 a DECORATIVE, durable and corrosion resistant. Aluminium is widely used for anodizing process. (d) Cathodic Protection : It is the method of controlling corrosion of a metal surface 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.
