Corrosion phenomena means to the deterioration of metallic materials due to chemical and electrochemical reactions, because these materials are always trying to reach a state of lower energy potential. Corrosion has many implications in terms of economic issues, security concerns and preservation of materials, so its study and mitigation is highly important. Herein some information is provided about, (1) certain types of corrosion which can be commonly observed, (2) Some factors that influence the corrosion process and speed, and (3) certain types of methods for controlling of corrosion and protection of materials.
