The electrochemical nickel plating process is a process in which a layer of metallic nickel is deposited onto objects as a result of applying a potential difference between the anode and the cathode.

Unlike the electroplating of precious metals such as gold, palladium and ruthenium, where the coating is in the range of tenths of a micron or, at most, a few microns, in the case of nickel plating, the coating deposited is several tens of microns thick, and in some cases even several millimetres.

Before depositing nickel onto the surface of the object, the surface must be thoroughly cleaned; otherwise, flaking may occur.

From a functional point of view, nickel plating is used to improve corrosion resistance and resistance to wear, abrasion and friction.
