Abstract

L'invention concerne un procédé de carbonitruration de pièces en alliage métallique consistant à soumettre lesdites pièces à l'action d'un mélange carburant constitué d'éthylène et d'hydrogène et à l'action d'un gaz nitrurant constitué d'ammoniac, sous une pression inférieure à 100 hPa et à une température d'environ 750 à 1050 °C. Il est particulièrement avantageux pour le traitement d'aciers passivables ou inoxydables car il permet d'atteindre des enrichissements superficiels en azote beaucoup plus élevés.
