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 electrolytic cell; the … 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 in the 1930s had observed a number of very fine silver objects from ancient Iraq, plated with very thin layers of gold, … See more • Anodizing • Electrochemical engineering • Electrogalvanization See more Electroplating changes the chemical, physical, and mechanical properties of the workpiece. An example of a chemical change is when See more There are a number of alternative processes to produce metallic coatings on solid substrates that do not involve electrolytic reduction: • See more The Hull cell is a type of test cell used to semi-quantitatively check the condition of an electroplating bath. It measures useable current … See more The Haring–Blum cell is used to determine the macro throwing power of a plating bath. The cell consists of two parallel cathodes with a fixed anode in the middle. The cathodes are … See more WebElectroplating uses electrolysis to put a thin layer of a metal onto a metal object. The electrodes used in electroplating are non-inert - they do take part in the electrolysis reactions....

WebElectroplating Electrolysis is used to electroplate objects (coat them with a thin layer of metal). This is useful for coating a cheaper metal with a more expensive one, such as … WebElectroplating, or electrolytic plating, is a technique in which a thin layer of metal is deposited, using an electric current, onto an object to enhance the surface … WebElectroplating Electrogalvanized (electroplated) coatings are created by applying zinc to steel sheets and strips by electro-deposition.
