Electroplating wikipedia
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. The copper layer can be decorative, provide corrosion resistance, increase electrical and thermal conductivity, or improve the adhesion of additional deposits to the substrate. Webelectroplating and electrorefining. Therefore, the process requires two electrodes (an anode and a cathode) immersed in a conducting electrolyte containing metallic salts and a source of DC power. As current is passed between the two electrodes, metallic ions in solution e.g. Ni ++, are converted into atoms on the cathode surface and these ...

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. The part to be coated acts as the cathode (negative electrode) of an … See more The electrolyte should contain positive ions (cations) of the metal to be deposited. These cations are reduced at the cathode to the metal in the zero valence state. For example, the electrolyte for copper plating can be a solution of See more It has been theorized that the first electroplating was done in Parthian Empire era. Wilhelm König was an assistant at the National Museum of Iraq See more The Haring–Blum cell is used to determine the macro throwing power of a plating bath.
