Corrosion is a chemical change and erosion is just a physical one. Explanation: Corrosion is an electrochemical process by which certain materials (eg iron) undergo a change in their oxidation state and combine with some compound present in the environment. #M (s) + O_2 (g) rarr M_xO_y (s)#.
Corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and stopping corrosion.
