What is the process of electroplating?

Electroplating is a process that involves applying a thin layer of metal onto the surface of an object through electrodeposition. This is achieved by passing an electric current through a solution containing metal ions, which causes the metal to be deposited onto the substrate. The primary purpose of electroplating is to enhance the surface characteristics of the object, such as improving corrosion resistance, reducing friction, or providing a more aesthetically pleasing finish.

In contrast, coating surfaces with protective paint focuses on non-metal layers and does not involve the use of an electrical current or metal ions; rather, it relies on chemical bonding or adhesion. Heating metal to change its properties refers to metallurgical processes such as annealing or tempering, which alter the physical and mechanical properties of the metal without adding a coating. Removing rust from metal surfaces pertains to the maintenance and restoration of metals already affected by corrosion, which is a different process altogether.
