Title (EN) SLURRY FORMULATIONS FOR FORMATION OF REACTIVE ELEMENT-DOPED ALUMINIDE COATINGS AND METHODS OF FORMING THE SAME
(FR) FORMULATIONS EN SUSPENSION POUR LA FORMATION DE REVÊTEMENTS D'ALUMINURE DOPÉS PAR UN ÉLÉMENT RÉACTIF ET LEURS PROCÉDÉS DE FORMATION
Abstract:
(EN) Novel slurry formulations and processes for forming improved protective coatings used in the hot section components of gas turbine engines are provided. The process includes a unique two-step deposition methodology whereby the required concentration of reactive element within an improved reactive element doped aluminide coating can be consistently produced in a reproducible manner.
(FR) L'invention concerne de nouvelles formulations en suspension et des procédés pour former des revêtements de protection améliorés utilisés dans les éléments de section chaude de moteurs à turbine à gaz. Le procédé comprend une méthodologie de dépôt unique à deux étapes, la concentration requise en élément réactif dans un revêtement d'aluminure amélioré, dopé par un élément réactif, pouvant être produite de manière constante et reproductible.
