Beschreibung
Zusammenfassung:	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. Se proporcionan novedosas formulaciones en suspensión y procesos para formar revestimientos protectores mejorados usados en componentes de la sección caliente de motores de turbines de gas. El proceso incluye una metodología única de depósito en dos etapas por la cual la concentración requerida del elemento reactivo dentro de un revestimiento de aluminuro impurificado con elemento reactivo mejorado puede producirse consistentemente de forma reproducible.
