It provides a protective layer over the surface of metal which protects the inner metal from further destruction.2. The galvanization takes the advantage of corrosion process by coating the another metal over the surface of the metal to make the metallic item new.The disadvantages of corrosion are as follows:1. The metal particles are lost from the surface.2. The physical appearance of the metallic object get changed.3. This reduces the quality and value of the material in the market.4. This reduces the life of the metallic objects. Rusting of any iron surface,naturally Surface corrosion forms an oxide layer which further protects the inner metal form corrosion. Corrosion prevents corrosion : Some metals like zinc are used as sacrificial anodes to prevent corrosion to other metal. ... The main disadvantages of corrosion of metal are: Lose of metal from the surface. Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment.Advantages of corrosion:\tProtection : Surface corrosion forms an oxide layer which further protects the inner metal form corrosion.\tCorrosion prevents corrosion : Some metals like zinc are used as sacrificial anodes to prevent corrosion to other metal.\tGalvanic corrosion : The principle on which primary batteries work.The main disadvantages of corrosion of metal are:\tLose of metal from the surface.\tChange in the physical appearance of a metal object.\tChange in chemical properties of metal.\tLose of the efficiency of metallic machines.\tA decrease in the life span of metallic objects. |
