Oxidation (of metals) (fr: Oxydation – des métaux): A form of metal corrosion that can occur either in the air or after the metal is exposed to acids or water. Metal oxidation takes place as a result of a chemical reaction occurring on the metal’s surface while oxygen is present. During this process the electrons move from the metal to the oxygen molecules, leading to the generation of negative oxygen ions that enter the metal, creating an oxide surface. Old, rusted cars or rusted pieces of metal scrap are good examples of oxidation.
