Corrosion
Corrosion is the deterioration of metals due to chemical reaction. Most common form of corrosion is through oxidization of metal surfaces. Most metals tend to lose electrons to oxygen in the air or in water. This process results in an oxide with the metal and cause deterioration of metal surface. When oxidation takes place due to different metal in contact with one another, it is called galvanic corrosion. Electrolytic corrosion takes place in electronic equipment when water or moisture gets trapped between two electrical contacts.
