Nexelia™ for Thermochemical Treatment

• Nitrogen is a neutral gas for many metal alloys. Pure and dry nitrogen is an excellent protection atmosphere against oxidation.
• Active molecules are defined depending on the heat treatment process used:
  - Methanol is sprayed and cracked in the furnace to reach carbon potential needed for carburizing in the atmosphere.
  - Acetylene is often used as a carburizing agent for low-pressure carburizing process.
  - High-pressure nitrogen / helium are efficient for rapid cooling on gas-quenching processes.
  - Ammonia is used for nitriding, carbo-nitriding or nitro-carburizing to reach the hardness requirement for the part surface.
