Abstract
On combine un traitement de brasage au four et un traitement de nitruration douce au moyen d'un gaz. Le procédé consiste à soumettre la pièce en fer à un traitement de brasage au four dans un gaz contrôlé pour le brasage, à refroidir au four la pièce brasée à une température convenable permettant le traitement de nitruration douce au moyen d'un gaz, et à ajouter une quantité déterminée au préalable de gaz ammoniac au gaz contrôlé pour effectuer le traitement de nitruration douce au moyen d'un gaz de la pièce dans l'atmosphère obtenue. Application à la peinture des véhicules.
