Abstract
Le procédé de trempe sous gaz de pièces d'acier ayant subi un traitement thermochimique comporte l'introduction, dans une enceinte (2) de trempe sous gaz, d'un flux de gaz de refroidissement en phase liquide, par exemple de l'azote ou de l'eau. Le procédé peut comporter également une introduction d'un premier gaz avant l'introduction du gaz de refroidissement sous forme liquide.
