Definition

Electroplating means a process by which a layer (metal, alloy, composite, etc.) is produced in an electrolyte under the influence of an electrical current on a conducting substrate. The electrolyte (also called plating bath) contains ions of the material to be plated.

Theory and Application

The theory of electroplating is closely related to the theory of charge transfer processes at electrified interfaces (Bard and Faulkner 2001).

Typical applications comprise the cathodic deposition of metal and alloy layers for surface finishing applications. Many recipes can be found in Schlesinger and Paunovic (2010).

Most electroplating processes are cathodic processes in which the layers are formed by cathodic reduction. As an example let us consider the technically important process of zinc deposition. A simple zinc electroplating bath could be made up by dissolving zinc sulfate in water. The part to be coated...
