Brazing of titanium-aluminium intermetallic alloy to nickel based superalloy using an interposed layer of nickel, notably for the production of aircraft engine components

The fixing on the surface of a first component (1) of a first metal of a second metal (4) by melting a solder (3) adapted to the second metal. The first metal is an intermetallic alloy such as titanium-aluminium and a layer of nickel (2) is interposed between the first component and the solder. An i...

Beschreibung
Zusammenfassung:	The fixing on the surface of a first component (1) of a first metal of a second metal (4) by melting a solder (3) adapted to the second metal. The first metal is an intermetallic alloy such as titanium-aluminium and a layer of nickel (2) is interposed between the first component and the solder. An independent claim is also included for a composite metal component obtained by this method. Une couche de nickel (2) interposée entre une pièce (1) en aluminiure de titane et une feuille de brasure (3) permet de braser cette pièce (1) à un autre matériau métallique (4) sans que l'aluminium diffuse de l'une vers l'autre, et d'obtenir ainsi une liaison stable ayant une bonne résistance mécanique.Application à l'assemblage de pièces de moteurs aéronautiques en aluminiure de titane et en un superalliage à base de nickel.
