The success of every commercial and industrial product, ranging from aero engines to airplanes, from electronic devices to surgical implants and from razor blades to racing cars; relies on the application of surface engineering. Imagine a world without computers, airplanes, trains, cars, medical implants, buildings, mobile phones, electronic devices, in fact virtually no manufactured products – that's a world without surface engineering. Electroplating is one of the process of surface engineering. Electroplating is the application of a metal coating to a metallic or other conducting surface by an electrochemical process. It is a process that uses electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode. Electroplating is primarily used to change the surface properties of an object (namely abrasion and wear resistance, lubricity, corrosion protection, aesthetic qualities, etc.), but may also be used to build up thickness on undersized parts or to form objects by electroforming.
