Electro deposition

During an electro-plating process a metallic coating is formed on the surface of objects like wires. Wires pass through a chemical solution that contains the corresponding ions of the metal of the coating. By applying a potential difference between the negatively charged cathode wires and the positively charged metal anode, the metal from the anode dissolves and simultaneously on the wires the metal deposits and forms the coating. A metal coating can offer improved corrosion resistance, a better electrical conductivity, a good adherence to other materials, nicer aesthetics and so on. Electro-deposition is mostly used to apply coatings of copper, nickel, tin and zinc.
