electroplating

Science Dictionary
electroplating   (ĭ-lěk'trō-plā'tĭng)  Pronunciation Key 
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.
