Peening of cooled turbine blade tip

A method for peening the tops of cooled blades which include cooling air passage orifices. Peening is performed by mobilization of a plurality of beads in a sealed chamber containing at least one blade tip. The plurality of beads is mobilized by the active surface of a sonotrode which delimits part...

Beschreibung
Zusammenfassung:	A method for peening the tops of cooled blades which include cooling air passage orifices. Peening is performed by mobilization of a plurality of beads in a sealed chamber containing at least one blade tip. The plurality of beads is mobilized by the active surface of a sonotrode which delimits part of said chamber. The beads have a diameter greater than that of the cooling air passage orifices.
