Definitions
- Typical coatings of this kind are from the U.S. Patents 4,005,989 and 4,034,142 known.
- the problem typically arises that increasing the proportions of elements such as aluminum and chromium, which can improve the resistance of a protective layer against oxidation and corrosion, leads to a deterioration of the ductility of the protective layer, so that mechanical failure, in particular formation of cracks, is expected in a gas turbine usually occurring mechanical stress.
- the invention is u. a. based on the knowledge that the protective layer in the layer and in the transition region between protective layer and base material brittle rhenium precipitates shows.
- these brittle phases which form increasingly with time and temperature, lead to pronounced longitudinal cracks in the layer as well as in the interface layer base material with subsequent detachment of the layer.
- the brittleness of the rhenium precipitates increases as a result of the interaction with carbon, which can diffuse into the layer from the base material or diffuse into the layer during a heat treatment in the furnace through the surface. Oxidation of the rhenium phases further enhances the driving force for crack formation.
