The present invention relates to a method for repairing or renewing cooling holes of a coated component of a gas turbine, having the following steps: - removal of an old coating from an outer side (2) of the component (1). The cooling hole (5) has an old cross section after removal of the old coating in a longitudinal section (11), which old cross section is greater than a setpoint cross section which the cooling hole (5) has in an original new state of the finished component in this longitudinal section. - application of a new coating (3', 4') to the component (1) at least in the longitudinal section (11) of the cooling hole (5), in such a way that the cooling hole has an intermediate cross section (16) in the longitudinal section (11), which intermediate cross section (16) is smaller than the setpoint cross section (6), - partial removal of the new coating (3', 4') within the cooling hole (5), in such a way that the cooling hole (5) has a new cross section (18) in the longitudinal section (11), which new cross section (18) is approximately as large as the setpoint cross section (6).

La présente invention concerne un procédé pour réparer ou remettre en état des trous de refroidissement d'un composant enduit d'une turbine à gaz. Ce procédé consiste à retirer un ancien revêtement d'une face extérieure (2) du composant (1), le trou de refroidissement (5) présentant dans une partie longitudinale (11), une fois l'ancien revêtement retiré, une ancienne section transversale supérieure à une section transversale de consigne, que ce trou de refroidissement (5) présentait à un état neuf initial du composant fini dans cette partie longitudinale, à appliquer ensuite un nouveau revêtement (3', 4') sur le composant (1) au moins dans la partie longitudinale (11) du trou de refroidissement (5), de sorte que ce trou de refroidissement présente, dans la partie longitudinale (11), une section transversale intermédiaire (16) inférieure à la section transversale de consigne (6), puis à retirer partiellement le nouveau revêtement (3', 4') à l'intérieur du trou de refroidissement (5), de sorte que ce trou de refroidissement (5) présente, dans la partie longitudinale (11), une nouvelle section transversale (18) approximativement égale à la section transversale de consigne (6).
