Title
(EN) TURBINE DISK FATIGUE REJUVENATION
(FR) RAJEUNISSEMENT DE LA FATIGUE D'UN DISQUE DE TURBINE
Abstract
(EN)
A process for rejuvenating a turbine disk having a plurality of slots includes the steps of determining a depth of a damaged layer containing M23C6 carbide dissolution; and removing the damaged layer from the slots in accordance with the determined depth.
(FR)
Processus de rajeunissement d'un disque de turbine possédant plusieurs fentes comprenant les étapes consistant à déterminer une profondeur d'une couche endommagée contenant une dissolution de carbure M23C6 ; et à retirer la couche endommagée des fentes conformément à la profondeur déterminée.
