Question

What is corrosion ? How corrosion occurs​

Answer 1

Corrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide.

In the presence of moisture, an oxidation reaction takes place on the energized area of the metal surface to elute metal as an ion (anode). On the metal surface, oxidation on anode and reduction on cathode proceed in equal rates and metal corrosion takes place. Normally, corrosion of metal occurs on anode.
