Emerging Trends in Liquid Nitriding Technology

Our team of HEF Group engineers is engaged in R&D activity to advance Liquid Nitriding technology, including new amp; innovative nitriding chemistries that can be used effectively at lower operating temperatures without compromising productivity. Liquid nitriding using appropriate chemicals, coupled with application-specific pre and post nitriding treatments/processes can deliver significant performance advantages.

ARCOR DT

  • New low temperature nitriding technology facilitates maximum nitriding kinetics at lower temperatures.
  • Low temperature nitriding (500-525°C) preserves core hardness for treated components.
  • In contrast, using traditional nitriding chemistries at lower temperatures leads to higher costs and greater waste.

ARCOR CS

  • Post-Nitriding impregnation treatments, using proprietary compounds, significantly enhance corrosion resistance. This is also a good option for compounds requiring low-friction run-in behavior.

Nitriding Treatments differ based upon:

  • Choice of nitriding chemistry
  • Processing temperature & time
  • Cooling options
  • Post-Nitriding metal finishing and surface impregnation options
