Metal plating provides many benefits to products made from metal and other materials.This is mostly achieved through electroplating, which requires an electric current, or through electroless plating, which is in autocatalytic chemical process. Not only must the metal to be electroplated be specified, but also its thickness and often other properties specific to the use of the article. Electroplating or Electro-deposition is a process where, an electrically conductive surface of an object is deposited with a metal. A cyanide-copper solution, for example, gave adherent deposits of copper directly on iron and steel. The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode. Electroplating is generally done for two quite different reasons: decoration and protection. Plated surfaces are less susceptible to damage when struck or dropped, which … Build thickness: Electroplating is often used to build up the thickness of a substrate through the progressive use of thin layers.

Not only must the metal to be electroplated be specified, but also its thickness and often other properties specific to the use of the article. The design engineer and others responsible for specifying finishes must know the purpose of the finish in order to specify it intelligently. Plating metal may be transferred to conductive surfaces (metals) or to nonconductive surfaces (plastics, wood, leather) after the latter have been rendered conductive by such processes as coating with graphite, conductive lacquer , electroless plate , or a vaporized coating. Electroplating is uniquely suitable to faithfully reproduce the shape of the mandrel due to the diffusional nature of the metal ion deposition process. Electroplating is used in jewelry making to coat base metals with precious metals to make them more attractive and valuable and sometimes more durable. METAL COATING FOR NICKEL CHROME. The point is to improve the surface of metal by increasing its luster or resistance to corrosion. Electroplating gives smooth and attractive finish to the crude metal objects. Electroplating is the process of plating one metal over another. Electroplating is the process of applying one or more layers of a metal to a part by passing a positively charged electrical current through a solution containing dissolved metal ions (anode) and a negatively charged electrical current through your part to be plated (cathode). In a slightly more limited way, it is hard to say what is the "purpose of electroplating". The term 'Electroplating' refers to the process of coating a metal with another metal by the process of hydrolysis. Eventually, due to contamination, the quality of the coated objects drops. The process uses chemical nickel plating baths. Aluminum requires special handling, Titanium requires a different special handling. Probably corrosion resistance is the single biggest use, but decorative application, hardness and wear resistance, electrical conductivity, reduced coefficient of friction, and a broad range of other properties can be achieved through electroplating. The part to be coated acts as the cathode of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode is usually either a block of that metal, or of some inert conductive material. Can you electroplate all metals? Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes.
