Rusting is the process where iron turns into iron oxide when it comes into contact with water and oxygen. It is a type of corrosion that occurs naturally. The chemical names for rust include iron oxide, ferric oxide, and hematite. The best ways to prevent iron from rusting are to spray paint it, put oil on it, or apply melted wax. Galvanizing, which involves coating iron or steel with a protective layer of zinc, is another effective way to prevent rusting. Other metals that can rust include steel, copper, and bronze.
