Patent

CA 2189642

A process and apparatus are provided for separating components of a brazed vane assembly (1) by preheating the assembly to a temperature below the solidus of the base metal of the vane assembly and above the liquids of the braze, then maintaining such temperature while separating the airfoil (23) from the platform (45) by pulling /pushing the airfoil (23) and platform apart (45).

L'invention se rapporte à un procédé et un appareil de séparation de composants d'un ensemble d'aubes (1) brasées, ce procédé consistant à préchauffer l'ensemble à une température inférieure à la température solidus du métal de base de l'ensemble d'aubes et supérieure à la température liquidus de brasage, puis à conserver cette température tout en séparant la surface portante (2, 3) du rebord (4, 5) en les tirant/poussant pour les écarter.
