What Is Corrosion?

Corrosion is a process whereby materials deteriorate as the result of the reaction between them and their surrounding environment. Since iron and steel are the materials most widely used in construction today and they are subject to corrosion, it is of primary importance to control corrosion, in order to prolong the service of life of structures and equipment fabricated from these materials. Because the mechanisms of corrosion are very complex, a detailed study of corrosion goes beyond the scope of dissertation.
