What is Electroplating?
Electroplating is a chemical or electrochemical process of surface treatment. A metallic layer is deposited on the base material. Common plating metals include: cadmium, chromium, copper, gold, nickel, silver and their alloys. This information bulletin focuses on chrome plating. Why Is Electroplating Important? Electroplating is used for components and equipment in all fields of technology to: protect the material against corrosion improve the surface properties achieve optimum decorative effects What Are The Sources Of Exposure In Chrome Plating? The main source of exposure is to tank contents (for example, mists, gases, vapours) that become airborne due to tank agitation, tank temperature, dipping of parts, parts moving along on hanging conveyors as well as batch changing activities and tank recharging. How Are The Metal Parts Cleaned Prior To Chrome Plating? Before plating, most metal surfaces are cleaned in a degreaser, conditioned for the plating process in a series of acid and ca
The electroplating of metals is generally carried out in order to improve the appearance or corrosion resistance of a surface by electrodepositing a thin layer of some desired metal on it. Electroplating In electroplating, the plating metal is generally the anode, and the object to be plated is the cathode. A solution of a salt of the plating metal is the electrolyte. The plating metal is deposited on the cathode, and the anode replenishes the supply of positive ions, thus gradually being dissolved. Electrotype printing plates, silverware, and chrome automobile trim are plated by electrolysis. at the anode: The metal to be electroplated to the surface is oxidized to cations which enters the plating solution. M(s) Mn+(aq) + ne- at the cathode: The cations in the plating solution migrates to the cathode, where they are reduced to metal and deposited onto the surface of the metal being plated.
