Nitrocarburizing / Salt Bath Nitriding

nitrocarburizingIonic liquids offer a significant improvement in wear protection, sliding properties and fatigue strength on all kind of ferrous materials. A subsequent oxidizing quenching produce a major increase in corrosion resistance. Due to the main process characteristics like

  • excellent reproducibility on high quality level
  • shortest treatment times
  • most negligible distortion
  • highest flexibility

This technology gives often superior results to that of galvanic layers and other nitrocarburizing processes.

Salts for nitrocarburizing

With TENIFER and ARCOR we offer two different environment-friendly salt bath nitriding processes. Which of both nitriding processes is the most appropriate one depends on the requirements and the geometry of the parts. Our Technical Sales Department will be pleased to giving you advice to make the right choice.
