Zusammenfassung:	A process of depositing a ceramic coating on an airfoil component and the component formed thereby is provided. The process includes depositing a bond coat on an airfoil component including on a trailing edge region thereof that defines a trailing edge of the airfoil component, within holes located within the trailing edge region and spaced apart from the trailing edge, and on lands located within the trailing edge region and between the holes. A ceramic coating is then deposited on the bond coat including on the trailing edge region of the airfoil component, within the holes located within the trailing edge region, and on the lands between the holes. The ceramic coating within the holes is selectively removed without completely removing the ceramic coating on the trailing edge region and the lands between the holes. L'invention concerne un procédé de dépôt d'un revêtement céramique sur un composant de profil aérodynamique et le composant formé par ce procédé. Le procédé comprend le dépôt d'une couche de liaison sur un composant de profil aérodynamique y compris sur une région de bord de fuite de celui-ci qui définit un bord de fuite du composant de profil aérodynamique, au sein de trous situés à l'intérieur de la région de bord de fuite et espacés du bord de fuite, et sur des parties planes situées au sein de la région de bord de fuite et entre les trous. Un revêtement céramique est ensuite déposé sur la couche de liaison y compris sur la région de bord de fuite du composant de profil aérodynamique, au sein des trous situés à l'intérieur de la région de bord de fuite, et sur les parties planes entre les trous. Le revêtement céramique au sein des trous est éliminé de façon sélective sans éliminer complètement le revêtement céramique sur la région de bord de fuite et les parties planes entre les trous.
