electroplating

/ ĭ-lĕk′trō-plā′tĭng /

The process of coating the surface of a conducting material with a metal. During the process, the surface to be covered acts as a cathode in an electrolytic cell, and the metal that is to cover it acts as an anode. Electroplating is usually used to cover a less expensive metal with a more expensive metal, or to cover a corrosive metal with a less corrosive or noncorrosive metal.

electroplating

A process whereby a thin coat of metal is applied to a material. The process involves placing the material to be coated in a solution containing ions of the metal and then passing an electric current (see also current ) through the system, which causes the ions to adhere to the material.
