ELECTROPLATING ON METALS
[CODE NO.3391]
Electroplating is a reliable and fast deposition process through which an adherent metallic coating is obtained on a vast variety of metal surfaces. This process of applying protective & decorative coatings has so greatly advanced that properties, dimensions of coat and coating rates can be strictly controlled. Tin, Silver, Rhodium, Platinum, Palladium Zinc, Iridium, Lead, Gold, Nickel, Chromium, Copper, Brass & aluminum are the most used coatings on variety of metal substrates. Any metal & metal alloy product produced in industries can be provided with suitable protective/decorative coating with the use of proper electrolyte bath, electroplating equipments & accessories, anodes/cathodes and control instruments while discussing adherent coating, it is advisable to understand that electroformed adherent coating is obtained exclusively by electroplating while electro deposition coatings may include electroless plating and immersion processes too. It is remarkable that practical & technological phases of electroplating matured even before Faraday's laws of electrolysis was pronounced. Until World War-I, electroplating was considered an art. The then electroplaters did not bother to know even the fundamentals of electricity and chemical reactions that took place in the electroplating process. At that time, appearance & appeal of the electroplated surfaces were considered more important than the physical & chemical properties of the coat. It was around World War - II that close tolerances & rigidly specified properties converted electroplating into a technology from its art - status.
