Chrome plating is achieved by the process of electroplating, a technique in which dissolved metal cations are reduced in a salt electrolyte bath to form a seamless metal coating on the desired object. Dirt is first removed from the workpiece, and often a layer of material is pre-treated before being placed in the chrome bath.
