Corrosion is the process by which metal degrades in the presence of various oxidizing agents in the environment. Corrosion takes many forms and can have many root causes. One common example of this is the process of rusting, during which iron oxides form in the presence of moisture.Corrosion is a serious problem for the makers of buildings, boats, aircraft, cars, and most other metal products.orrosion takes many forms and can have many root causes.
