Title
(DE) VERFAHREN ZUR ERHÖHUNG DER OXIDATIONSBESTÄNDIGKEIT VON NI-BASISLEGIERUNGEN DURCH DIE BEHANDLUNG MIT HALOGENEN
(EN) METHOD FOR INCREASING THE OXIDATION STABILITY OF NI-BASE ALLOYS BY MEANS OF TREATMENT WITH HALOGENS
(FR) PROCÉDÉ POUR AUGMENTER LA RÉSISTANCE À L'OXYDATION D'ALLIAGES À BASE DE NICKEL PAR TRAITEMENT AVEC DES HALOGÈNES
Abstract
(DE)
Das Einbringen von Halogenen (Fluor, Chlor, Brom, Jod) auf die Oberfläche bzw. in den oberflächennahen Bereich von Ni-Basiswerkstoffen kann die Oxidationsbeständigkeit von Ni-Basislegierungen im Temperaturbereich von 700°C bis 1300°C gegenüber unbehandelten Ni-Basislegierungen deutlich erhöhen. Die Halogene bzw. Halogenverbindungen können durch verschiedene Verfahren, z. B. durch Ionenimplantation, Eintauchen, Streichen, Besprühen oder Gasphasentransport, auf die Oberfläche aufgebracht bzw. in den oberflächennahen Bereich der Bauteile eingebracht werden.
(EN)
The incorporation of halogens (fluorine, chlorine, bromine, iodine) on the surface, or the regions close to the surface, of Ni-base materials can significantly increase the oxidation stability of Ni-base alloys in the temperature range from 700°C to 1300°C compared to untreated Ni-base alloys. The halogens, or halogen compounds, can be applied to the surface by means of different methods, such as by means of ion implantation, immersion, painting, spraying, or gas phase transport, or can be incorporated in the region of the components that is close to the surface.
(FR)
L'introduction d'halogènes (fluor, chlore, brome, iode) sur la surface ou dans la région proche de la surface de matériaux à base de nickel peut augmenter considérablement la résistance à l'oxydation d'alliages à base de nickel dans la plage de température de 700°C à 1300°C, par rapport à des alliages à base de nickel non traités. Les halogènes ou composés halogénés peuvent être apposés sur la surface ou introduits dans la région proche de la surface des éléments par différents procédés, par exemple par implantation ionique, immersion, enduction, pulvérisation ou transport en phase gazeuse.
