Abstract

L'invention concerne une aube (10) pour turbomachine, en particulier une aube pour turbine à gaz, qui présente une feuille d'aube (11) dotée d'un bord d'attaque (13) de l'écoulement et d'un bord de fuite (14) de l'écoulement, un côté d'aspiration et un côté sous pression de la feuille d'aube s'étendant entre le bord d'attaque de l'écoulement et le bord de fuite de l'écoulement. Selon l'invention, au moins dans la zone occupée par le bord d'attaque (13) de l'écoulement, la feuille d'aube (11) est revêtue d'une couche ductile de protection contre l'usure, la couche ductile de protection contre l'usure présentant des particules céramiques dures incorporées dans une matrice métallique.
