Plasma nitriding


Maximum usable furnace space: Ø 1,500 mm/6,000 mm height
Maximum batch weight: 10.000 kg
Under our brand name PLASNIT® we offer highly developed plasma nitriding heat treatments for a wide range of steel grades.

Our plasma nitriding system MICROPULS® Everest ensures plasma nitriding processes in premium quality with the RUBIG's MICROPULS® Technology.

PLASNIT® processes from RUBIG represent the technological top of nitriding technology and are constantly being further developed. The standard processes cover the recommended spectrum of nitriding hardness depth and compound layer thickness for all common, nitridable steels. In addition, we develop individual plasma nitriding processes to meet every requirement for nitriding hardness depth, compound layer thickness, corrosion protection and oxide layer thickness – for individual parts up to large series.
PLASNIT® stands for environmental friendliness, improved corrosion properties and the highest reproducibility.

Advantages of Plasnit®

Partial treatment possible

Partial nitriding is possible by mechanical covering.


Good reproducibility and close tolerances in the treatment result.

Clean surfaces

Less roughness and clean surfaces compared to salt bath and gas.

Cost saving

Ready–to-install products - reduced production costs.

Corrosion protection

Increased protection against corrosion in unalloyed and low-alloy steels.


Possibility of post-oxidation.
