METHOD FOR CARBONITRIDING

In a method for carbonitriding at least one metal part, the metal part is heated in a heating phase to a treatment temperature, is nitrided in at least one nitriding phase using a nitrogen donor gas, and is carburized in at least one carburizing phase using a carbon donor gas. The first nitriding ph...

Beschreibung
Zusammenfassung:	In a method for carbonitriding at least one metal part, the metal part is heated in a heating phase to a treatment temperature, is nitrided in at least one nitriding phase using a nitrogen donor gas, and is carburized in at least one carburizing phase using a carbon donor gas. The first nitriding phase begins after the termination of the heating phase and before the beginning of the first carburizing phase.
