Definitions
- the invention relates to a two-layer ceramic heat-insulating layer in which high-purity zirconium oxide is used.
- GZO gadolinium zirconate
- the figure shows schematically a layer system.
- nickel or cobalt-based superalloys are used in particular for turbine components or components for high temperature applications.
- a metallic adhesive layer 7 is present on the substrate 4, in particular directly on the substrate 4, a metallic adhesive layer 7 is present.
- this is a primer layer 7 of a NiCoCrAlX coating, wherein X represents rhenium (Re), yttrium (Y), silicon (Si), iron (Fe) and / or tantalum (Ta).
- X represents rhenium (Re), yttrium (Y), silicon (Si), iron (Fe) and / or tantalum (Ta).
- Re rhenium
- Y yttrium
- Si silicon
- Fe iron
- Ta tantalum
- a ceramic thermal barrier coating 13 is applied with an inner ceramic layer 15 and an outer ceramic layer 18 on the inner ceramic layer 15th
- the outer ceramic layer 18 is preferably also the outermost layer.
- the materials for the inner ceramic layer and the outer ceramic layer 15 are preferably the same.
- the inner ceramic layer 15 preferably comprises a zirconium oxide layer which is partially stabilized, with yttrium (Y), very particularly preferably only yttrium (Y), being used for the stabilization.
- Y yttrium
- Y very particularly preferably only yttrium
- the proportion of yttrium (Y) is preferably 8% by weight.
- the outer ceramic layer 18 preferably also has zirconium oxide, but with respect to the inner zirconium oxide layer 15 is at least 20% purer, in particular at least 50 6 pure, of chemical impurities.
- the proportion of yttrium (Y) here is also preferably 8
- the chemical impurities of the ceramic layers 18, 15 are in particular hafnium oxide and / or aluminum oxide and / or silicon oxide and / or iron oxide and / or titanium oxide and / or magnesium oxide and / or calcium oxide.
- Purity can be based on one, several or all Impurities ⁇ gene of the powder or of the film produced.
- the outer ceramic thermal barrier coating 18 preferably has a porosity of 16% to 24%, in particular of 18% to 22%, very particularly of 20%.
- the porosity is preferably measured in vol%.
- the inner ceramic layer (15) has an at least 3vol% lower porosity.
- the outer ceramic layer (18) is Minim ⁇ least 10%, carried out in particular 20% thicker to better utilize the heat insulating effect ⁇ . Due to the lower proportions of impurities and thus melting point lower deteriorated sintering properties are given, so that the layer can withstand the higher tempera ren while maintaining the porosity longer at higher temperatures.
