what is corrosion explain its advantage and disadvantage
Answers
Explanation:
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:
Protection : 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.
Galvanic corrosion : The principle on which primary batteries work.
The main disadvantages of corrosion of metal are:
Lose of metal from the surface.
Change in the physical appearance of a metal object.
Change in chemical properties of metal.
Lose of the efficiency of metallic machines.
A decrease in the life span of metallic objects.
