Electroplating layers
WebThe Definition of Nickel Plating. The process of nickel plating involves electrolytically depositing a layer on a metal surface. However, there is also the process of electroless nickel plating which is an auto-catalytic reaction where you deposit the coating onto a substrate. There’s no need for an electric current as in nickel electroplating. WebElectroplating is the deposition process of a metallic film onto a seed metal layer, which works as a cathode (negative electrode) in an aqueous solution (bath) of a salt of the …
