Definitions
- the invention relates to a ceramic material which can be used in particular for the use of ceramic layers.
- the use of zirconium oxide-based ceramic materials is known from the use for ceramic heat shields made of solid material or ceramic protective layers on turbine blades or high-temperature components. It is important that there is a high sintering resistance, phase stability, high fracture toughness and high elongation tolerance.
- the object is achieved by a ceramic material according to claim 1.
- Figures 1, 2 show schematically layer systems made of a ceramic material.
- yttrium oxide Y2O3
- cerium oxide CeCg
- calcium oxide CaO
- magnesium oxide MgO
- s base oxide
- Er203 erbium oxide
- Yb203 ytterbium oxide
- Such a ceramic layer has in particular a layer thickness of 20 mm to 100 mm, in particular up to 2000 mm and can preferably be produced by means of thermal spraying, in particular APS or EB-PVD.
- the ceramic material has a high sintering resistance, a high elongation tolerance and high fracture toughness, and it has a lower thermal conductivity.
- ZrO 2 + Y 2 O 3 is not the subject of the invention (disclaimer).
- FIG. 1 shows a layer system 1 according to the invention.
- the layer system 1 has a substrate 4.
- the substrate 4 is in particular a nickel-based superalloy or is a CMC substrate.
- a bonding layer is present on the substrate 4, which is a connection layer in particular in the case of a nickel-based superalloy
- NiCoCrAlY-based alloy or an aluminide or a platinum-aluminide layer.
- TGO An oxide layer (TGO) forms on this metallic adhesion promoter layer during coating or during operation.
- a ceramic layer according to the ceramic material is applied on this oxide layer (TGO) or on the metallic adhesion promoter layer 7.
- FIG. 2 A variant is shown in FIG. 2 in which the layer system 1 'is formed in two layers with respect to the ceramic protective layer 10'. The same applies to FIG. 1 with regard to the substrate 4 and / or the substrate materials of the connection layer 7. However, the outermost ceramic layer 16 forms the ceramic material of the invention here.
- this ceramic layer 16 there is a ceramic connection layer 13 for the purpose of adapting thermal expansion coefficients or adapting the porosities.
- the segmented ceramic layer 10, 16 has a density of 90% to 96% of the theoretical density, in particular 92% to 95% of the very particular theoretical density, so that the density is in particular> 5.5 g / cm 3 .
- the ceramic powder preferably has a grain size distribution of 10 mm to 65 mm.
- the depth of the vertical macro cracks 20 in the ceramic layer 10, 16 is at least 75% of the thickness of the ceramic layer, in particular the depth of the macro cracks should be 20 to at least 90% of the layer thickness. Only these are counted when specifying the density of the macro cracks per millimeter.
