Electroplating

• Electroplating is coating the surface of a metal with a thin layer of another metal.
• Galvanising is coating metals in zinc as it is unreactive so prevents corrosion.
• To electroplate a metal you need to have:

  • An anode made from the plating metal
  • An electrolyte - a solution with ions of the plating metal
  • A cathode that is the metal object
