Question

What do you mean by corrosion?

Answer 1

Corrosion is actually a chemical or electrochemical reaction between metal and its environment. The smelted iron and other metals used in buildings, equipment, and vehicles have a higher energy content than their counterparts in nature, such as iron oxide. As a result, metals like iron and steel are unstable and have a tendency to corrode to their natural state by combining with other elements. Overtime they combine with oxygen to form iron oxide, i.e. rust or corrosion.
