• Alfanit Nitriding (Liquid Nitriding ) for Wear Resistance on finished components.
• Alfanit is a Liquid Nitriding or Nitrocarburizing and Surface Hardening process used on fully finished components.
• Alfanit improves the life of the Ferrous Components especially on Engineering Parts, Sothat the warranty claims can be reduced.

Advantages :

• Alfanit improves the resistance to Wear, Seizure, Galling, Fatigue, Corrosion on Steels, Stainless Steels and Cast Iron Components.
• Fully Finished Components can be treated by Alfanit process as it gives least distortion.
• Components which require shallow case depth by Carburising, Carbonitriding etc. can be changed to Alfanit Process.
• Costlier High Alloyed Steels can be replaced by Alfanit treated Mild Steel or Low Alloyed Steel.

Typical Application :

Automobile, Textile, Hydraulics, Heavy Machineries, Railways Military, Mining, Machine Tools Plastic, Glass, Aluminium Extrusion, Wire Cutting & Drawing, Pump, Forging, Die Casting etc.

• Gas Nitriding process provides several advantages for the alloys treated, such as high surface hardness, wear resistance, anti-galling, good fatigue life, corrosion resistance and improved sag resistance at temperatures up to the nitriding temperatures.
• Gas nitriding is typically done using ammonia with or without dilution of the atmosphere with dissociated ammonia or nitrogen (or nitrogen/hydrogen) in the temperature range of 925-1050°F (500-565°C).
• Ammonia (NH3) is allowed to flow over the parts to be hardened.
• Due to the temperature and the catalytic effect of the steel surface, the ammonia dissociates into atomic nitrogen and hydrogen in accordance with equation 2NH3 → 2N + 6H.

• Nitrocarburizing is a variation of the nitriding process.
• It is a thermochemical diffusion process where nitrogen, carbon, and to a very small degree, oxygen atoms diffuse into the surface of the steel part, forming a compound layer at the surface, and a diffusion layer.
• Nitrocarburizing is a shallow case variation of the nitriding process.
• Advantages of the process include the ability to harden materials which are not prehardened, the relatively low temperature of the process which minimizes distortion, and relative low cost in comparison to carburizing or other case hardening processes.
• This process is done mainly to provide an anti-wear resistance on surface layer and to improve fatigue resistance.
