Plasma nitriding with compound layer (PN)

Plasma nitriding is a thermochemical process for enriching the surface layer of a workpiece or component with nitrogen. Due to the nitrogen input, a diffusion layer and a compound/precipitate layer develops. Due to the high level of wear resistance, this method is especially suitable for highly mechanically stressed parts.

Compound layer: up to 15 µm
Precipitate layer: up to 0.8 mm

Some application examples:

  • Axles
  • Aluminium die-casting tools
  • Drive rollers
  • Extruder screws
  • Mould inserts
  • Glass moulds
  • Plastic injection-moulding tools
  • Crankshafts
  • Machine components
  • Press plungers
  • Pump parts
  • Worms
  • Clamping levers
  • Shafts

Plasma nitriding without compound layer (compound-layer-free PN)

During compound-layer-free plasma nitriding, only a precipitate layer forms due to the low nitrogen input. The formation of a compound layer is prevented. This enables a significant increase in fatigue strength through the introduction of compressive residual stress in the tough surface layer.

Compound layer: 0-3 µm
Precipitate layer: ≤ 0,3 mm

Some application examples:

  • Ejector pins
  • Bending tools
  • Drills
  • Springs
  • Transmitter wheels
  • Piston rings
  • Coupling springs
  • Embossing dies
  • Cutting tools
  • Punching tools
  • Cup springs
  • Torsion damper springs
  • Valves
  • Valve springs
  • Cutting tools
