Electroplating rate
WebNov 4, 2024 · Electroplating is the application of electrolytic cells in which a thin layer of metal is deposited onto an electrically conductive surface. A cell consists of two electrodes (conductors), usually made of metal, which are held apart from one another. The electrodes are immersed in an electrolyte (a solution). When an electric current is turned ... WebThe plating rate changes dramatically as the carrier is increased from 0-1 mL/L. As the carrier concentration is increased beyond 1 mL/L, there is little additional effect on the plating rate. The brightener has a different …
