Patent

CA 2629219

The invention relates to a method for producing metallic components, particularly for turbomachines, having small edge radii, said method comprising the following steps: mechanical and/or electrochemical machining of the component and creating a small edge radius; solidifying the small edge radius by ultrasound shot peening. This avoids the disadvantages of the prior art and a mechanical, automatizable method is disclosed that permits a significant saving of time and personnel and leads to reproducible results. The invention also relates to a component produced thereby.

Procédé de fabrication de pièces métalliques, en particulier pour des turbomachines, à petits rayons d'arêtes, qui comporte l'usinage mécanique et / ou électrochimique d'une pièce avec réalisation d'un petit rayon d'arête, et la consolidation du petit rayon d'arête par grenaillage par ultrasons. Ledit procédé évite les inconvénients liés à l'état actuel de la technique et consiste en un procédé mécanique, pouvant être automatisé, qui permet une économie considérable en temps et en personnel et conduit à des résultats reproductibles. La présente invention concerne également une pièce ainsi fabriquée.
