|
Answer» SOLUTION :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. |
