Metal Electroplating

Metal electroplating have been applied over recent decades. Many application on using of electroplating process have been developed for many purposes like enhance the corrosion resistance, or for decorative purposes to make some metal have better appearance.

For other purposes the characteristic of electroplating often use because of electroplating is often also called as electro deposition. Electro deposition is the process of producing a coating, usually metallic, on a surface by the action of electric current. The deposition of a metallic coating onto an object is achieved by putting a negative charge into one electrode cell. The metal ion like salt carry a positive charge and are thus attracted to the object. This method often use on collecting metal from the solution that may be have high concentration. The result like to extract something from mixing solution then we can collect of just metal that dissolve in the solution.

Electroplating uses a form of electrolysis in which the electrodes play a bigger role than just conducting the current. Using electric current we can coat metal of one electrode with the metal of other. Jewelry and silverware can be silver, or gold plated, while zinc is often used to coat iron to protect against rust.
