AnoBlack Ni is Anoplate’s proprietary industrial, black nickel deposit, meeting requirements of MIL-P-18317. AnoBlack Ni deposits a gray-to-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 on 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 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.
