Electroplating is the process of coating a metal with a thin layer of another metal by electrolysis to improve the metal’s resistance to corrosion. Iron articles are electroplated with copper, chromium, tin or nickel for decorative purposes in jewellery, and for the durability of cutlery and motor parts. 
 
Articles made of iron are electroplated to make them shine and to prevent iron from getting rusted. Example: Chromium plating is done on many objects such as car parts, bathroom taps, kitchen gas burners, bicycle handlebars and wheel rims.
