  Electrodeposition  1. Introduction to Electrodeposition Electrodeposition (also called electroplating or electrochemical deposition ) is a process where a solid coating is deposited onto a conductive surface (substrate) by the reduction of metal ions from a solution using an electric current . Fundamental Principle: The metal ions in the electrolyte are reduced at the cathode (substrate) and deposit as a thin film. 2.
