Abstract

La réparation ou le remplacement d'une partie en saillie telle qu'une dent (10) d'un joint en labyrinthe en métal présentant une caractéristique de soudabilité relativement mauvaise s'effectue en enlevant une portion ou éventuellement la totalité, de la dent jusqu'à un socle (26), puis en liant métallurgiquement au socle, par exemple par fusion, un second métal ayant une bonne caractéristique de soudabilité lorsqu'il est dilué avec le premier métal, et pouvant etre durci par l'age avec un traitement thermique de vieillissement avec lequel le premier métal est également durci par l'age. Application à la réception de joints fixes et tournants, en particulier pour moteurs à turbine à gaz.
