Black Nickel

Definition:
Electroless black nickel-phosphorus plating is an advanced electroless nickel plating process formulated to deposit a black finish. It is a decorative functional RoHS compliant metal finish. The black nickel will mask the surface condition of the substrate. Dull parts will plate matte black nickel. Polished parts will have high gloss black nickel appearance. Heat treating the black nickel will increase corrosion resistance, harden the black layer and stabilize the deposit color. Black nickel is a conductive finish which can be used as a replacement for anodize when the non conductive finish is inappropriate for the function. The black nickel finish is used with a low phosphorus electroless nickel, but a base layer of medium or high phosphorus electroless nickel can be used to increase corrosion resistance. Black nickel popularity is growing in the defense, aerospace, ammunition, mechanical and electronic industries.
