Abstract

a. L'invention concerne un procédé et une installation pour réaliser sur des pièces des couches de protection contre la corrosion par des gaz chauds et/ou l'usure mécanique en insufflant dans un jet de gaz chaud ionisé une poudre de revêtement essentiellement constituée par un alliage et en projetant cette poudre sur la pièce. b. Le procédé est caractérisé en ce qu'on effectue sous vide la projection de la poudre de revêtement c. L'invention est applicable en particulier à la protection des aubes des compresseurs et des turbines dans les turbines à gaz.at. The invention relates to a method and an installation for producing protective layers on parts against corrosion by hot gases and / or mechanical wear by blowing in a jet of hot ionized gas a coating powder consisting essentially of an alloy. and spraying this powder on the part. b. The process is characterized in that the spraying of the coating powder is carried out under vacuum c. The invention is particularly applicable to the protection of compressor blades and turbines in gas turbines.
