Definitions
- EP 0 379 699 A1 describes a method for increasing the Corrosion and oxidation resistance of a blade thermal machine, especially a compressor blade an axial compressor.
- the basic material of the compressor blade consists of a ferritic-martensitic Material.
- a solid is placed on the base material adhesive surface protective layer consisting of 6 to 15 % By weight silicon, rest aluminum according to the high-speed process with a particle velocity of at least 300 mls sprayed onto the surface of the base material.
- This metal protective layer is made according to a conventional one Paint spraying process a plastic, for example polytetrafluoroethylene, applied which plastic the top layer (outer layer) of the blade. With the procedure a protective layer is provided on a blade which increased resistance to corrosion and erosion when present of water vapor and comparatively moderate temperatures (450 ° C), as relevant for compressor blades are.

Abstract
L'invention concerne un élément (80) pouvant être soumis à l'action de vapeur chaude, comprenant un corps de base (81) métallique auquel est liée par diffusion une couche de protection (82) pour augmenter la résistance à l'oxydation du matériau de base. Cette couche de protection (82) comporte de l'aluminium et a une épaisseur (D) de moins de 50 νm. L'invention concerne en outre un procédé permettant de produire un revêtement de protection pour augmenter la résistance à l'oxydation d'un élément (80).
