Answer» Electroplating is known as electrodeposition because the process involves depositing a thin layer of metal onto the surface of a work piece, which is referred to as the substrate. An electric current is used to cause the desired reaction. Here's a simplified explanation of how electroplating works: Let's suppose that a layer of gold is to be electrodeposited onto metal jewelry to improve the appearance of the piece. The plating metal, or coating, (gold) is connected to the anode (positively charged electrode) of the electrical circuit, while the jewelry piece is placed at the cathode (negatively charged electrode). Both are immersed in a specially developed electrolytic solution (bath). At this point, a DC current is supplied to the anode, which oxidizes the metal atoms in the gold and dissolves them into the bath. The dissolved gold ions are reduced at the cathode and deposited (plated) onto the jewelry piece. Factors that impact the final plating result include: the chemical composition and temperature of the baththe voltage level of the electric currentthe distance between the anode and the cathodethe electrical current application's length of time Electroplating is the process of depositing a thin metal coating on other metal to improve their appearance looks .Application of electroplating : Decoration Purpose :Some metals give better look and finish.For example , a flower vase of brass if electroplated with silver will be more attractive. Protection Against Corrosion:More reactive metals tend to get rusted often. To portect against corrosion, we use electroplating.For example :Iron can be protected by coating it with Zinc and Nickel.Brass objects are coated with chromium.Repairing Finer Machine parts:Minor repairs[small and precise ] in machines can be done by coating the place with required metal. |
