Heat treatment

Plasma nitriding

Plasma nitriding is one of the thermochemical heat treatment processes and is carried out at temperatures between 350 and 600° C.

Positively charged ions strike the workpieces connected as a cathode in front of the furnace wall (anode) with a high impact speed.

Initially, this ion bombardment results in a very intense cleaning of the workpiece surface (sputtering), followed by the heating and nitriding of the surface.

Advantages compare to gas nitriding:

  • Smaller distortion
  • Adaptation of layers to wear type
  • Partial nitriding much easier to achieve
  • Environmentally,less gas consumption
  • No additional depassivation for stainless steel nitriding
  • Titanium nitriding
