Abstract

Le procédé de nitruration a pour but de conférer é des pièces en métal ferreux, outre les propriétés de surface résultant directement de la nitruration, une résistance à
la corrosion comparable à celle que l'on obtient en faisant suivre le traitement de nitruration d'un traitement d'oxydation, notamment en bains de sels. Suivant le procédé
de l'invention, on traite les pièces par immersion pendant une durée appropriée dans un bain de sels en fusion constitué de façon connue en soi essentiellement de cyanates et carbonates de métaux alcalins et contenant une petite quantité d'une espèce soufrée, on porte les pièces, par rapport à une contrélectrode plongée dans le bain, à un potentiel positif tel qu'un courant substantiel traverse le bain des pièces à la contrélectrode, et l'on maintient la teneur en cyanures formés en réaction secondaire à une valeur inférieure à 6%. I1 est préférable de travailler à
courant moyen constant; les densités de courant typiques sont de 300 à 800 ampères par m2, la gamme typique de températures 450°-650°C, et les durées typiques s'échelonnent entre 10 et 150 min.
