What is black nickel plating?

Black nickel plating involves the process of coating brass, bronze or steel objects with a thin layer of nickel by means of electrolysis. Black nickel plating produces a thin jet black finish.

Black nickel plating is typically used for decorative purposes. It is also used for engineering and electroforming projects. Black nickel plating creates a non-reflective surface on objects treated with this process. Electroplating involves careful preparation of the part to be plated, which is then immersed into an electrolyte solution known as an electrolytic bath. An electrochemical process occurs resulting in this specialized coating.

Strict regulations on the international electroplating industry have been initiated, as of 2014. Concerns related to possible negative health effects associated with metal contamination have led to the strengthening of these environmental regulations.
