Precision black coating for a variety of substrates
AnoBlack Ni is Anoplate’s proprietary industrial, black nickel deposit. AnoBlack Ni deposits a grayto-black thin coating which is useful to reduce glare, or absorb light in the IR or UV spectrum.
Unlike other black coatings which can particulate and disturb sensitive optical instruments even after precision cleaning, AnoBlack Ni has been proven to pass precision cleaning protocols.
Because the AnoBlack Ni coating is so thin, it cannot be relied up for any corrosion protection. When improved corrosion performance is required, a nickel underplate can be applied which meets the requirements of AMS-QQ-N-290 or AMS 2404.
AnoBlack Ni provides a highly conductive surface and has excellent “throw” or ability to plate uniformly on complex geometries. An underplate of electroless nickel can further enhance the lubricity of the overall deposit. Black nickel can be used where high emissivity is required such as optics, solar panel applications, aerospace and defense weapons systems.
AnoBlack Ni meets and exceeds the requirements of MIL-P-18317.
AnoBlack Ni can be applied to a wide variety of materials, including:
- Stainless Steel
- Inconel, Monel, Invar, Covar
- Brass & Copper
Additionally, AnoBlack Ni can be applied on heavier or more intricate rack-plated parts, or in barrel for smaller parts – barrel plating being much more economical in higher volumes.
Typical solar absorbency values obtained from spectral reflectance curves over a wavelength range of 0.5 – 2.5 µm range from 0.88 to 0.96. The infrared emittance over the same wavelengths ranges from 0.07-0.10.
AnoBlack Ni should be applied where maximum wear life and corrosion resistance are required. AnoBlack Ni is an excellent solution for the following applications:
- Optical light paths
- Precision-cleaned optical components
- Communications headsets

Film Thickness & Tolerances
AnoBlack Ni is very thin as-deposited, however for corrosion protection it is typically deposited over an underplate of electro-deposited or electroless nickel. For post-plating fit, the tolerances on the nickel underplate will have to be taken into consideration.
Typically, the rougher the surface finish incoming or duller the underplate, the more gray the plated part will appear. Conversely, the blackest AnoBlack Ni coatings are deposited on to smoothest surfaces
