Plasma nitriding


Maximum usable furnace space: Ø 1,500 mm/6,000 mm height
Maximum batch weight: 10.000 kg
PLASOX® is a special treatment and describes our PLASNIT® processes with subsequent oxidation.

As a result of this targeted post-oxidation, an oxide layer is incorporated into the compound layer. In addition to improving the sliding properties, it causes an increase in corrosion resistance. The combination of plasma nitration and postoxidation can be carried out both in a single process and in two separate processes. The PLASOX® treatment turns the plasma nitrided parts dark gray to matte black.

We recommend PLASOX® for components that require a certain degree of corrosion inhibition and act as a friction partner for another hardened part.

Advantages of Plasox®

Extended service life

Increased strength and customized surfaces.

Short process chain

Minimization of hard fine machining and mechanical covering.


Safety through reproducible processes.


Depending on the component requirement, the coating can be adapted accordingly, regardless of the component geometry.


The PLASOX® process opens up many more applications.

Environmental friendliness

No use of toxic gases.

Necessary information:
  • Surface hardness
  • Nitriding hardness depth
  • Compound layer thickness/oxide layer thickness
  • Definition of the area to be nitrided (as an indication on the construction drawing)
