Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction ...
George Richards Elkington (1801–1865) by Samuel West The old Elkington Silver Electroplating Works in Birmingham Commemorative inkstand, about 1850, Elkington & Co. V&A Museum no. 481&A-1901 George Richards Elkington (17 October 1801 – 22 September 1865) was a manufacturer from Birmingham , England.
Being much harder than copper, it was used from the mid-1830s but only for articles such as trays or cylindrical items that did not require complex shaping. After about 1840 the Sheffield plate process was generally replaced with electroplating processes, such as that of George Elkington. Electroplating tends to produce a "brilliant" surface ...
In 1802, Brugnatelli successfully carried out the first gilding electroplating experiments [4] with the coating of carbon electrodes by a metallic film, finally refining the process in 1805 for which he used his colleague Volta's invention of five years earlier, the voltaic pile, to facilitate the first electrodeposition. He hypothesized that ...
Parkes was put in charge of the casting department, and his attention soon began to focus on electroplating. Parkes took out his first patent (No. 8905) in 1841 on a process for electroplating delicate works of art. His improved method for electroplating fine and fragile objects, such as flowers, was granted a patent in 1843.
Michael Faraday began, in 1832, what promised to be a rather tedious attempt to prove that all electricities had precisely the same properties and caused precisely the same effects. The key effect was electrochemical decomposition. Voltaic and electromagnetic electricity posed no problems, but static electricity did.

Such zinc electroplating or zinc alloy electroplating maintains a dominant position among other electroplating process options, based upon electroplated tonnage per annum. According to the International Zinc Association, more than 5 million tons are used yearly for both hot-dip galvanization and electroplating. [ 1 ]
