Working Principle – Electroplating

Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. It is used to change the surface properties of an object (such as abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities), and may also be used to build up thickness on undersized parts or to form objects by electroforming. We will see this process in this experiment.
