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)#.
Pitting Corrosion. Pitting corrosion is a localized form of corrosion by which cavities or holes are produced in the material. Pitting is considered to be more dangerous than uniform corrosion damage because it is more difficult to detect, predict and design against.Corrosion products often cover the pits. A small, narrow pit with minimal overall metal loss can lead to the failure of an entire engineering system.itting: corrosion of a metal surface, confined to a point or small area, that takes the form of cavities. Pitting factor: ratio of the depth of the deepest pit resulting from corrosion divided by the average penetration as calculated from weight loss.
