Definitions
- the invention relates to a ceramic layer system for thermal insulation, the other layers for protection against
- Invasion of CMAS includes.
- Heat-insulating layers of partially stabilized zirconium and / or gadolinium zirconate are coated.
- Contaminants such as CMAS lead to chemical attacks of the ceramics and also to penetration of liquid phases into the pores of the ceramics. At the same time, the abrasion of the
- Compressor abradables an upstream compressor to unique nickel coatings on the layers. This too leads to TBC flaking due to reduced thermal expansions. So far, there is no system against this multiple attack.
- the problem is solved by a layer system according to
- FIG. 1 shows a layer system according to the invention
- FIG. 2 is a list of superalloys. The figure and the description only represent
- a platinum layer is preferably applied as the lower erosion protection layer 13.
- This lower erosion protection layer 13 is intended to prevent penetration of the CMAS (CMAF) layer.
- This lower erosion protection layer 13 may have a layer thickness between a few ⁇ to ⁇ .
- a layer of aluminum particles preferably with a thickness of 50 ⁇ to 300 ⁇ applied to this lower erosion control layer 13.
- hollow spheres of aluminum oxide are formed.
- the spheres bind to the platinum via the formation of platinum aluminide.
- the platinum has an expansion coefficient adapted to the thermal barrier coating.
- Applied alumina has a lower
- the platinum layer may also preferably be supported by titanium oxide or Mg 2 A10 4 and / or
- the inventive step is the application of the
- FIG. 1 shows a layer system 1 according to the invention comprising a substrate 4.

- the substrate 4 may contain various metallic materials
- Attachment layers 7 may be present.
- Y yttrium
- Re rhenium
- Ta tantalum
- Fe iron
- An oxide layer has already grown on the metallic bonding layer 7 (TGO aluminum oxide not shown) on which a further ceramic thermal barrier coating material 10 is present.
- This ceramic thermal barrier coating material 10 may be a zirconium oxide layer with various stabilizers and / or a pyrochlore structure or else a two-layer or multi-layer TBC, in particular an inner zirconium oxide layer with an outer pyrochlore structural layer, in particular gadolinium zirconate (GZO).
- GZO gadolinium zirconate
- Such layer systems are state of the art and, according to the invention, additionally have a lower erosion protection layer 13 made of platinum, titanium oxide, magnesium aluminate (Mg 2 A10 4 ) or iron aluminate (Fe 2 A10 4 ).
