How to Blacken Electroless Nickel Coatings

In this video, Surface Technology, Inc. demonstrates a simple process to blacken the surface of electroless nickel coatings using the Surf-Black solution. One-Plate electroless nickel makes this process especially easy and consistent. Black EN can be made with either the medium phosphorous or low phosphorous versions of One-Plate. Black electroless nickel coatings are often useful for aerospace, consumer and tactical products. Please see the other videos on our ‪@STI-SurfaceTechnology‬ channel, and let us know any assistance we can provide related to electroless nickel; especially our One-Plate single component electroless nickel and composite coatings with diamond, Teflon, boron nitride, silicon carbide, and others.

What's in the "surf-black" solution?

[@STI-SurfaceTechnology]

The solution is a combination of sulfuric acid, hydrogen peroxide, and proprietary ingredients. I hope this information is helpful.
