Abstract

a. Procédé pour réaliser des couches de surface possédant des propriétés anti-corrosion améliorées sur des pièces en alliages de fer et de chrome, et couche de surface réalisée par ce procédé. b. Procédé caractérisé en ce que la pièce est chauffée dans une atmosphère gazeuse contenant de l'oxygène sous un vide total d'environ 10**-1 à 10** -8 mm Hg, de préférence environ 10**-5 mm Hg, à une température à laquelle devient perceptible la diffusion, sur la surface, du ou des constituants de l'alliage les plus réactifs, en particulier le chrome, du fait de sa tendance à se combiner à l'oxygène, température à laquelle les autres propriétés de l'alliage sont essentiellement maintenues, tandis que l'état décrit de la pièce est conservé jusqu'à une couche de surface contenant du chrome oxydé ait cru jusqu'à une épaisseur de préférence comprise entre 10**-9 et 10**-7 m, la couche de surface obtenue se transformant progressivement, pour ce qui est de sa structure et de sa composition, d'un certain état à la surface à l'état correspondant à celui de la matrice de l'alliage métallique. c. L'invention s'applique notamment à la protection des pièces utilisées en milieu agressif.at. Process for producing surface layers having improved anti-corrosion properties on parts made of iron and chromium alloys, and surface layer produced by this process. b. A method characterized in that the part is heated in a gaseous atmosphere containing oxygen under a total vacuum of about 10 ** - 1 to 10 ** -8 mm Hg, preferably about 10 ** - 5 mm Hg, at a temperature at which the diffusion, on the surface, of the most reactive constituent (s) of the alloy, in particular chromium, becomes perceptible, due to its tendency to combine with oxygen, at which temperature the other properties of the alloy are essentially maintained, while the described state of the part is maintained until a surface layer containing oxidized chromium has grown to a thickness preferably between 10 ** - 9 and 10 ** -7 m, the surface layer obtained gradually transforming, as regards its structure and its composition, from a certain state to the surface to the state corresponding to that of the matrix of the metal alloy. vs. The invention applies in particular to the protection of parts used in an aggressive environment.
