The invention relates to a method for producing a coated turbine blade (40), with which the frequency property thereof can be particularly easily adjusted to the required boundary conditions. To this end, recesses are introduced into a tip (4) of the vane (42) of the turbine blade (40) after coating of the turbine blade (40).

L'invention concerne un procédé de fabrication d'aubes mobiles de turbine recouvertes et une bague d'aube mobile pour un rotor d'une turbine à impulsions axiales. L'invention concerne un procédé de fabrication d'une aube mobile de turbine (40) recouverte, permettant d'adapter ses caractéristiques de fréquence de manière particulièrement simple aux conditions marginales nécessaires. A cet effet, l'invention prévoit que la mise en place d'évidements dans une extrémité d'aube (4) du corps d'aube (42) de l'aube de turbine (40) ait lieu uniquement après le recouvrement de l'aube mobile de turbine (40).
