chemical action which causes destruction of the surface of aa material by oxidation or chemical combination. Also caused by reduction of the electrical efficiency between a metal and a contiguous substance or to the disintegrating effects of strong electrical currents or ground return currents in electrical systems. The latter is known as electrolytic corrosion.

Corrosion occurs in all metals at some time and can be divided into four basic forms. Room temperature oxidation, the most common form, is most obvious in mild and low-alloy steels. The process is accelerated dramatically by comparatively small amounts of contaminants like chloride, sulfate, and fluoride. When exposed to high temperatures, metals will almost invariable result in oxidation of metal surfaces. ...

chemical reaction on the surface of a coin. Corrosion can result from a coin coming in contact with other things (chemicals) including chemicals in the air. This can come about because of things coming in contact with the coin years earlier. Corrosion damages a coins surface and is usually worse in copper, nickel, zinc, and silver coins. Some experts think that toning on the surface of a coin may help slow down this harmful process. Also see "toning".
