Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.

Apart from Leopoldo Nobili, who already in 1824 performed his first experiments related to the appearance of Nobili's rings, Leonhard Elsner, Alexander Watt, Antoine César Becquerel (1788–1878) and Rudolf Christian Böttger (1806–1881) also dealt with the electrochemical coloring of metals in that early period.
Copper electroplating is the process of electroplating a layer of copper onto the surface of a metal object. Copper is used both as a standalone coating and as an undercoat onto which other metals are subsequently plated. [ 1 ]

electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or salt. [1] anodizing – electrolytic passivation process used to increase the thickness of the natural oxide layer, producing a porous surface which can accept organic or inorganic ...
By definition, the electrode potential for the SHE is zero. Thus, the Cu is the cathode and the SHE is the anode giving E cell = E°(Cu 2+ /Cu) – E°(H + /H 2) Or, E°(Cu 2+ /Cu) = 0.34 V. Changes in the stoichiometric coefficients of a balanced cell equation will not change the E° red value because the standard electrode potential is an ...
A simplified diagram of electroplating copper on a metal. Electroplating is a chemical surface-treatment technique. It involves bonding a thin layer of another metal such as gold, silver, chromium or zinc to the surface of the product. This is done by selecting the coating material electrolyte solution, which is the material that is going to ...
