Salt Bath Nitriding

 

    A low temperature heat treatment, that produces outstanding wear resistance. corrosion resistance and fatigue properties while maintaining dimensional requirements with little or no distortion. Often replacing the more expensive processes of hard chrome or nickel plating, Salt Bath Nitriding gives better corrosion protection equivalent or lower costs. Salt Bath Nitriding, often referred to by its generic name of Salt Ferritic Nitrocarburizing or its trade name Melonite® has been specified and applied to a wide variety of automobile engine and transmission components. Salt Bath Nitriding is commonly used as an alternative to high temperature conventional heat treatments such as carburizing and carbonitriding. Applications include:
    • Hydraulics
    • Tubes
    • Shafts
    • Thrust Washers
    • Gears
    • Seating Tracks
    • Brackets
    • Brake Components
    • Friction Plates
      The Basics. 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 parts. Reproducible and uniform layers with a predetermined thickness will be formed on all areas of the parts. The result of this process is markedly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability.
