"Nitriding offers improved wear, abrasion, and corrosion resistance when compared to hard chrome lining or phosphating. The benefits are not limited to only these attributes, nitriding also offers a lower coefficient of friction. Unlike chrome lining where the chrome is built up on the surface, nitriding converts the surface with out the risk dimensional build up causing fitment and function issues."
BLACKNITRIDE™, or Ferritic Nitrocarburizing, is the thermochemical that simultaneously diffuses nitrogen and carbon into the surface of ferrous metals. During the process, a two-part surface layer is formed, an outer iron nitride layer with a nitrogen diffusion layer below it. During this treatment, nitrogen and carbon are absorbed by and diffused into the surface of the metal. Reproducible and uniform layers with a predetermined thickness will be formed on all areas of the metal. The result of this process is markedly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability.
Metal components treated with BLACKNITRIDE™ have increased wear-resistance, fatigue strength, corrosion resistance, lubricity and cosmetic appeal. Often replacing the more expensive processes of hard chrome or nickel plating, BLACKNITRIDE™ gives better corrosion protection at equivalent or lower costs. Additionally, BLACKNITRIDE™ is commonly used as an alternative to high temperature conventional heat treatments such as carburizing and carbonitriding.
Ferratic Nitride: This is the most advanced firearms finish we offer. Nitride offers exceptional wear resistance, excellent corrosion resistance and a uniform black color. This finish treats both the inside and outside of all parts of the rifle made of ferrous metal. Nitride will offer the benefits of a chrome lined bore without the disadvantages. As this finish is not a plating, but a heat treatment process, it actually changes the surface of the steel and preserves the finish characteristics (lapped finish) of the bore and can not flake off. Nitride will result in a surface hardness of nearly 70 Rockwell C scale, meaning that you can run a file across it and it will not scratch. Nitride is self-lubricating, eliminating the need to add oil to your firearm. This finish can be top-coated (with some surface prep) with DuraCoat or Film Transfer, allowing a variety of colors
