Abstract

L'invention concerne un procédé de réparation d'un composant (406), notamment d'un composant turbine à gaz qui est réalisé dans un matériau de base ayant une microstructure orientée. Ce procédé consiste à nettoyer la zone à réparer (420) ; à remplir la zone à réparer (420) d'un matériau de remplissage correspondant à la composition du matériau de base ; à effectuer un traitement thermique au niveau de la zone à réparer (420) remplie, ce matériau de remplissage présentant des particules (425a, 425b) micrométriques et/ou nanométriques. Lors du remplissage de la zone à réparer (420), on prend des mesures qui empêchent l'oxydation du matériau de remplissage et on adapte les températures et temps de maintien du traitement thermique à la composition du matériau de remplissage et du matériau de base du composant (406) de manière à obtenir une liaison épitaxique du matériau de remplissage au matériau de base environnant.
