Micropulse Plasma Nitriding

With plasma nitriding, the edge of a workpiece is either finished with nitrogen or with nitrogen and carbon (plasma nitrocarburising) in an ionised gas atmosphere. To improve the tribological characteristics of the component, it can then be oxidised.

Advantages

  • High level of resistance to wear and tear
  • Minimal distortion
  • Partial nitriding
  • Reduction in coefficient of friction

Materials

  • Low-alloy steels
  • Tool steels
  • Nitriding steels
  • Stainless steels

Available plant sizes

  • Length 1.200 mm, diameter 1.000 mm
