What is Ruthenium plating?
Plating ruthenium involves a process known as electrodeposition. This electroplating process deposits a thin layer of metal onto whatever substrate is used. The substrate is the material to which the ruthenium gets plated. Before applying plating to a substrate, it is necessary to prepare the surface.
