The invention relates to a method for carbonitriding a steel part placed in an enclosure (14) held at a low internal pressure wherein the steel part is held within a temperature range. The inventive method consists in alternating first and second stages, in injecting a cementing gas into the enclosure only during the first stages and in injecting a nitriding gas into the enclosure during at least one part of at least two second stages.

L'invention concerne un procédé de carbonitruration d'une pièce en acier disposée dans une enceinte (14) maintenue à une pression interne réduite, la pièce étant maintenue à un palier de température. Le procédé comporte une alternance de premières et de secondes étapes, un gaz de cémentation étant injecté dans l'enceinte seulement pendant les premières étapes et un gaz de nitruration étant injecté dans l'enceinte seulement pendant au moins une partie d'au moins deux secondes étapes.
