Abstract
L'invention concerne une installation et un procédé de traitement de surface et de mise en précontrainte de compression par grenaillage de la paroi (2C) d'au moins une cavité oblongue (2) formée dans une pièce (1), ladite cavité (2) débouchant à l'extérieur par une embouchure latéralé (2A), et ayant deux extrémités susceptibles de présenter des ouvertures (3). Le grenaillage de la paroi (2C) de la cavité (2) est réalisé par ultrasons en générant un brouillard de billes (10) dans une enceinte (12) délimitée par la paroi (2C) de la cavité (2), une surface vibrante (8A) obturant ladite embouchure (2A) de la cavité (2) et des moyens d'obturation (14) obturant lesdites ouvertures (3), au moyen d'une sonotrode (8) excitée par des moyens de production d'oscillations ultrasonores (18). Procédé et installation particulièrement destinés à traiter un disque de turbine (1), comportant une pluralité d'alvéoles axiales (2) formées à la périphérie dudit disque (1) et présentant des portions de parois (2'C) qui divergent à partir de chaque embouchure (2A).
