A process of removing ceramic deposits (22) from a surface hole (12) in a component (10), a particular example being portions of a ceramic coating (20) deposited on a surface (16) of a component (10) equipped with cooling holes (12). The process makes use of a pulsed Nd:YAG laser operated with parameters that avoid delamination, cracking or otherwise damaging a ceramic coating (20) surrounding a cooling hole (12). The laser is operated to generate a laser beam (24) that removes some of the ceramic deposit (22) from the hole (12) while a residual portion of the ceramic deposit (22) remains surrounding the hole (12) to define a surface opening.
Méthode d'enlèvement de dépôts de céramique (22) d'un trou de surface (12) d'une pièce (10), par exemple pour enlever certaines parties d'un revêtement céramique (20) déposé sur la surface (16) d'une pièce (10) comportant des trous de refroidissement (12). La méthode nécessite l'emploi d'un laser Nd-YAG pulsé suivant des paramètres qui évitent la délamination, les craquelures et tout autre dommage au revêtement céramique (20) entourant les trous de refroidissement (12). Le laser génère un faisceau laser (24) qui enlève une partie du dépôt de céramique (22) du trou (12), tandis qu'une partie résiduelle de ce dépôt (22) demeure autour du même trou (12) pour former une ouverture de surface.
