Black Nitride, 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. 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. This process results in markedly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability. Black Nitride is commonly used as an alternative to high temperature conventional heat treatments such as carburizing and carbonitriding.
Black nitride Benefits
• Increased wear resistance
• Improved fatigue strength
• Better corrosion resistance
• Improved lubricity
• Enhanced cosmetic appeal
• Better corrosion protection at equivalent or lower costs than hard chrome nickel plating

This was the second 1911 I had C&H black nitride do for me. They do an excellent job. I can customize my gun, de-burr, send it out for black nitride. When I get it back all parts fit exactly as before, reassembly, and ready to go. Looks great, has the wear and corrosion resistance I want.
I would recommend C&H services, they are very helpful and professional.

PERFECT !
Black Nitride is the way to go … absolutely durable and long lasting. C&H done an excellent job applying, This coating does NOT have any imperfections, evenly spread and looks and feels tough, combat ready !
I would highly recommend the “Black Nitride” and especially done by C&H, Bar-Non.
