· Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which batteries produce electric currents. All these things are examples of electrochemistry : chemical reactions caused by or producing electricity that give scientifically or industrially useful end-products.
Nickel, copper, cobalt, and gold are the most common metals plated in this process. Deposition rates are controlled by the amount of reducing agent present and the type of chelating agent used.

The electroplating process uses an anode and a cathode. In electroplating, the metal dissolved from the anode can be plated onto the cathode. The anode is provided with direct current, oxidizing and dissolving its metal atoms in the electrolyte solution. At the cathode, the dissolved metal ions are decreased and the metal is placed on the product.
Electroless nickel plating is a form of alloy treatment designed to increase resistance and hardness in a metal or plastic. The electroless nickel plating process is simpler than its counterpart electroplating.
