Definitions
- the invention relates to the protection of a thermal barrier coating against corrosion comprising hollow aluminum oxide spheres and further comprising a glassy outermost protective layer.
- the object is achieved by a method according to claim 1 with a component according to claim 2.
- FIGS 1, 2, 3 schematically Schichtsys ⁇ inventive systems with a corrosion protection layer.
- the inventive step is the application of a layer of aluminum particles, in particular by a slurry.
- Semi-metal in particular boron, silicon or germanium applied by spraying a slurry.
- Aluminum particles / Zirkonoxidpelle can one
- Particle layer can be between 5 and 150 ⁇ . This layer is optimally applied as a slip. But other methods are possible. By a suitable
- Coating system consisting of base material,
- Adhesive layer and TBC are formed from the
- the titanium group oxides increase the mechanical compatibility and the resistance to CMAS attack.
- a second optional layer has the composition of a low-melting, viscous glass whose
- Melting point is preferably lower or in the range of the melting point of the diffusing metal in the underlying layer.
- the glass is especially in
- Substantially S1O 2 and preferably contains for the
- melting point relevant accompanying elements such as Magnesium (Mg), calcium (Ca) or boron (B) and / or
- the glass can also be formed during the heat treatment in an oxygen-containing atmosphere from a silazane, siloxane or silicone polymer as a precursor. These precursors can be used to adjust the shrinkage and
- oxidation of the aluminum particles can be performed by the additional layer of glass without the pure aluminum particles running along the surface of the system clogging component holes during aging.
- the "hiking" of the aluminum particles can be performed by the additional layer of glass without the pure aluminum particles running along the surface of the system clogging component holes during aging.
- Aluminum / Titanium group metal particles (which belong to a
- Blockage of the cooling air bores can lead to
- the SiO 2 layer will then largely delaminate during operation due to brittleness and the actual protective layer may take over the protective effect.
- the inventive step is the composition and application of the aluminum / titanium group metal particles in
- Clog cooling air holes during removal The use of polymer masking may alternatively be performed. Boron enhances the chemical bonding of the additional layer.
- FIG. 1 shows a layer system 1 according to the invention which has a substrate 4.
- the substrate 4 is in particular metallic, wherein it has in particular ⁇ a special nickel or cobalt-based superalloy.
- an optional metallic adhesion promoter ⁇ mid layer 7 is present on the substrate 4 .
- this is one
- Coating layer in particular based on NiCoCrAlY.
- an oxide layer (TGO) is formed during the further coating or by deliberate oxidation or at least during operation, which is not shown here in detail.
- a ceramic thermal barrier coating 10 is present on this thermally grown oxide layer (TGO) or on the metallic adhesion promoter layer 7, a ceramic thermal barrier coating 10 is present.
- This may be single-layered, in particular of zirconium oxide or double-layered with zirconium oxide and a pyrochlore or "DVC" layers.
- Alumina particularly of alumina hollow spheres 14 ( Figure 1), but optionally as the outermost one
- a layer of aluminum particles, in particular with grain sizes of lym to 50ym applied, in particular by a slip, vapor deposition, sputtering, etc . This layer may have a layer thickness between some
- Additions to aluminum (Al) are preferred: in particular at least one element Z selected from the group I boron (B), gallium (Ga) and / or germanium (Ge) and / or
- Corrosion layer (13 13 ⁇ ⁇ , 13 ⁇ ⁇ ⁇ ) applied and / or oxidized as a material mixture or is oxidized.
- silicon (Si) and / or magnesium (Mg) can be applied and / or be present in the material mixture.
- Ge / Ga means: germanium and / or gallium, ie Ge, Ga or Ge + Ga.
- This layer should prevent the penetration of the CMAS (CMAF) layer and react with the CMAS (CMAF).
- CMAF CMAS
- the alumina thus applied has a lower coefficient of expansion, and in conjunction with the nickel (Ni) originating from the compressor abradable, part of the alumina breaks off. The remaining layer then protects against the penetration of liquid deposits.
- the inventive step is also in the application of the different particle sizes of the alumina
- the glass can in particular represent silicon oxide, in particular S1O 2 .
- zirconium (Zr) reduces the viscosity of the CMAS and prevents or
- At least one element from the group boron (B), gallium (Ga) and / or germanium (Ge) and optionally silicon (Si) is additionally present.
- alumina / zirconia or over the metallic aluminum / zirconium or over aluminum and an element Z may be a glass layer as explained above
- the heat treatment for the formation of alumina or alumina / zirconia or alumina and oxide of the element Z may be effected by a first use of the component or by an upstream heat treatment prior to the first use or after being placed in a machine for a
