When some metals are exposed to moistures, acids etc., they tarnish due to the formation of respective metal oxide on their surface. This process is called “corrosion”.
Corrosion can be prevented by painting, oiling, greasing, galvanizing, chrome plating or making alloys.
Galvanizing is a method of protecting iron from rusting by coating them a thin layer of zinc.
