In nitrocarburising, the surface layer of the work piece is enriched with nitrogen and carbon. The core structures remain unaffected. Combined with the alloying elements of the material, the nitrogen and carbon form a very hard layer called the compound layer. The thickness of the compound layer can be adjusted extremely precisely. Layer thicknesses of up to 20 μm are possible.


Nitrocarburisation is used above all in the finishing of unalloyed steels and machinery, as well as in construction steel. This process can significantly increase resistance to wear and corrosion. Due to the purely surface hardening, the elasticity of your components is retained. In many cases, the work pieces can be installed or used directly after heat treatment without reworking.




- no quenching process
- low dimensional change
- virtually no warping
- high resistance to wear
- goor corrosion protection (particularly when combined with oxidation)
- hardening for partial areas possible
- compound layer thicknesses up to 20 μm possible
- reproduceable process results
- treatment of bulk goods possible
