What is BLACKNTRIDE?

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.
