Abstract

L'invention concerne les revêtements protecteurs des superalliages. Elle se rapporte à un revêtement protecteur qui comprend une première couche formée de deux sous-couches et une couche externe d'oxyde tel que la zircone. La première couche comprend une première sous-couche formée d'une très fine poudre qui assure l'étanchéité au niveau de la surface du substrat, et la seconde sous-couche est formée d'une poudre de même composition mais plus grossière donnant une rugosité superficielle importante qui permet un bon accrochage de la couche d'oxyde. Application à la protection des éléments soumis à des atmosphères corrosives à température élevée.
