Abstract[English]
The invention relates to a rotor blade (30) in a gas turbine engine (50) characterized by a coating (10) on a blade tip (20) of the rotor blade (30) comprising an oxidation resistant abrasive layer (11) and the rotor blade tip (20) having at least partially an oriented surface (21) with a normal vector (22) with a component (23) in the rotational direction of the rotor blade (R). The invention further relates to a method of manufacturing the rotor blade (30) and a gas turbine engine (50) with the rotor blade (30).[French]
L'invention concerne une pale de rotor (30) dans un moteur à turbine à gaz (50) caractérisée par un revêtement (10) sur une extrémité de pale (20) de la pale de rotor (30) comprenant une couche abrasive résistante à l'oxydation (11), et l'extrémité de pale de rotor (20) présentant au moins partiellement une surface orientée (21) avec un vecteur normal (22) avec une composante (23) dans le sens de rotation de la pale de rotor (R). L'invention concerne en outre un procédé de fabrication de pale de rotor (30) et un moteur à turbine à gaz (50) équipé de la pale de rotor (30).
