Gas carbonnitriding is a thermal-chemical treatment applied to steel in an atmosphere enriched with nitrogen and carbon to create hard and wear-resistant edge layers. The excellent qualities of this procedure also include the reduction of the sliding resistance, improvement of the wear-resistance and higher ductility. In contrast to other hardening procedures, improvement of the achieved properties is not based on the creation of nitrides (gas nitriding) and/or carbonnitriding.
The corrosion protection can be significantly improved due to the after-oxidization of the thermal-chemically treated workpieces. The resulting change of the connecting layer can be recognised by its anthracite colour.
