SPUN METAL FORM USED TO MANUFACTURE DUAL ALLOY TURBINE WHEEL

A spun metal form used to manufacture a dual alloy turbine wheel. The spun metal form prevents braze alloy contamination of the hub/casting interface by relocating the braze joint away from the interface. The spun metal form allows for the re-working of components after failed vacuum brazing and inc...

Zusammenfassung:	A spun metal form used to manufacture a dual alloy turbine wheel. The spun metal form prevents braze alloy contamination of the hub/casting interface by relocating the braze joint away from the interface. The spun metal form allows for the re-working of components after failed vacuum brazing and increases the time to failure of dual alloy turbine wheels. L'invention concerne une forme de métal centrifugé utilisée pour la fabrication d'une roue de turbine à double alliage. Cette forme de métal centrifugé empêche la contamination d'alliage de brasage de l'interface moyeu/pièce moulée par repositionnement du joint de brasage à l'opposé de l'interface. Ladite forme de métal centrifugé permet de réusiner les composants après un brasage fort sous vide défaillant et augmente le temps avant défaillance de roues de turbine à double alliage.
