This process blackens the surface of electroless nickel plating to give it a jet-black color.
The surface is blackened by blackening treatment after processing a special electroless nickel plating.

Features
Features 1Appealing black surface
After performing electroless nickel plating, the outermost layer is dissolved and oxidized or sulfurized to obtain a black film with a chic look. Because fine bumps are formed on the surface by this treatment, the concave parts absorb visible light to reduce light reflection resulting in a deeper black color.
Features 2Uniform and dimensionally accurate plating
As with electroless nickel plating, the plating film thickness is uniform and dimensional accuracy is high.
