The electrolytic rhodium plating process is a process by which, by applying a potential difference between the anode and cathode, a layer of metallic rhodium is deposited on objects.

This type of treatment gives the treated objects a shiny white color that is appreciated in the jewelry sector.

As with all surface finishing treatments, to ensure good adhesion of the metal it is necessary to pre-treat the surface in order to make it suitable for galvanic coating.
