Abstract
L'invention concerne un procédé de carbonitruration d'une pièce en acier disposée dans une enceinte, comprenant des premières étapes et des deuxièmes 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 les deuxièmes étapes, au moins l'une des deuxièmes étapes étant située entre deux des premières étapes, la pression dans l'enceinte pendant au moins une partie desdites deux premières étapes étant maintenue à une première valeur et la pression dans l'enceinte pendant au moins une partie de ladite deuxième étape située entre lesdites deux premières étapes étant à une deuxième valeur supérieure strictement à la première valeur.
