Abstract

L'invention porte sur un procédé de décapage d'une barrière environnementale (13) déposée sur une pièce (10) composite comportant successivement: - un substrat (11) en matériau composite à matrice céramique, - une couche de liaison (12) en silicium, - une couche de silice protectrice (12.1), et - une couche de barrière environnementale (13), - ledit procédé de décapage comportant: - une étape de fissuration de la couche de barrière environnementale (13) jusqu'à la couche de silice protectrice (12.1), puis - une étape de dissolution de la couche de silice protectrice (12.1).
