Electroplating is done by the process of electrodeposition, and involves the formation of an electrolytic cell consisting of the cathode (the object to be plated) and the anode (the metal used for plating), immersed in an electrolytic solution.
The object to be plated and the metal are dipped into the aqueous solution containing the metal ions. As mentioned earlier, the electrolyte used in the tin process for the electrolytic coloring consists of an acid (usually sulfuric), dissolved tin salts, stabilizers, and color enhancers.

Carbon paste, glassy carbon paste. The electrolytic tinning of metallic bodies, for example, electro-tinning of steel strip, is conventionally effected by making the surface to be plated the cathode in an aqueous solution of tin salt, such as, stannous sulfate, stannous chloride or stannous fluoborate, in an acid bath and sodium stannate or potassium stannate in an alkaline bath.
Generally accepted as a critical step in most electroplating processes, surface preparation of metals prior to the metal electroplating is presented.
Definition of the clean surface influence of basis metal and the choice of cleaning methods are discussed. Soak, spray, electrolytic, acid. The word “electrolysis” was introduced by Michael Faraday in the 19th century. In chemistry, electrolysis is a method that uses a DC to drive a non-spontaneous chemical reaction.
