Plasma Nitriding & Post-Oxidation

Composition and characteristics

  • Optional follow-up treatment of nitrocarburized components
  • The corrosion resistance of nitrides cases can be increased by post-oxidation. The surface of the component gets a black, decorative look.
  • Oxide layer (ca. 1 – 2 µm)
  • White layer (10 – 20 µm)


  • Good wear resistance
  • Further increase of corrosion resistance
  • Improved running-in characteristics
  • Black, decorative look

Fields of Application

  • Corrosive and abrasive stressed components
  • Engine components with aggravated running-in characteristics
