Electroplating of silver
WebWhen the silver layer covers the copper so that no more copper is exposed to the silvering paste, the plating will stop. The plating industry has various names for this process, such as electrochemical replacement plating, immersion plating, displacement plating or galvanic deposition (Paunovic 2006). In metallurgy, it is called cementation. WebSilver plating, as mentioned, is essentially coating a metal with a layer of silver. The thickness of this coating is measured in microns (1 micron is approximately 0.0001 centimeter) and can range between 1-40 microns. For jewelry, this range is restricted to 1-10, with the average being around 2 microns.

This is useful for coating a cheaper metal with a more expensive one, such as copper or silver. The negative electrode (cathode) should be the object that is to be electroplated. The positive electrode (anode) should be the metal that you want to coat the object with.
