A process for detecting an aluminum-based material deposited onto a titanium- based gas turbine engine component during engine operation is disclosed. The process comprises immersing at least a portion of the titanium-based component, which has been subjected to engine operation, into an acid solution to form an etched component. The acid solution comprises sodium fluoride, sulphuric acid and water. The etched component may then be removed from the solution and visually inspected for dark areas in contrast to light areas, the dark areas indicating deposited aluminum-based material.
Divulgation d'un procédé de détection d'une matière à base d'aluminium déposée sur un élément de moteur de turbine à gaz à base de titane pendant le fonctionnement du moteur. Ce procédé comprend l'immersion au moins d'une partie de l'élément à base de titane, qui a été soumis au fonctionnement du moteur, dans une solution acide pour former un élément décapé. La solution acide comprend du fluorure de sodium, de l'acide sulfurique et de l'eau. L'élément décapé peut ensuite être retiré de la solution et inspecté visuellement pour détecter des zones sombres en contrast de zones claires, les zones sombres indiquant le dépôt d'une matière à base d'aluminium.
