Definitions
- the invention relates to a thermal barrier coating for metallic components, in particular for high-temperature loaded or hot gas loaded components of a gas turbine, having an inner contact layer and an outer cover layer, wherein the inner contact layer is applied to a surface of the component with the interposition of an adhesion-promoting layer. Furthermore, the invention relates to a component with such a thermal barrier coating.
- DE 100 08 861 A1 discloses a thermal insulation layer system for a metallic component, wherein the thermal insulation layer system consists of a contact layer and a cover layer. The contact layer is located between an adhesion-promoting layer and the cover layer, wherein the adhesion-promoting layer is applied to the component.
- DE 100 08 861 Al there is a contact layer of the thermal barrier coating system entirely or predominantly of Y 2 O 3 partially stabilized zirconium oxide or of a glass-metal composite, the outer layer is composed of fully stabilized cubic zirconia (ZrO 2).
- Object of the present invention is therefore to provide a thermal barrier coating of the type mentioned, which has a significantly improved erosion resistance.
- a thermal barrier coating according to the invention for metallic components in particular for components of a gas turbine subjected to high temperatures or hot gas, has an inner contact layer and an outer cover layer, wherein the inner contact layer is applied to a surface of the component with the interposition of an adhesion-promoting layer.
- an intermediate layer is formed between the outer cover layer and the inner contact layer, wherein the intermediate layer is formed from a material which consists of at least one component having at least one phase stoichiometrically 1 to 80 mol% Mx 2 O 3 , 0.5 to 80 mole% MyO and balance Al 2 O 3 with random impurities and Mx is selected from the elements lanthanum, chromium, barium, neodymium or mixtures thereof, and where My is selected from the alkaline earth metals, the transition metals and the rare earths or mixtures thereof, preferably of magnesium, zinc, cobalt, manganese, iron, nickel, chromium, europium, samarium or mixtures thereof, and the inner contact layer and the outer cover layer consist of a zirconium oxide partially stabilized with yttrium, yttrium oxide, calcium or magnesium.
- the intermediate layer Mx 2 O 3 as La 2 O 3 and MyO be performed as MgO, wherein the phase is a hexaaluminate phase of the magnetoplumbite structure.
- the intermediate layer consists in particular of lanthanum hexaaluminate, in particular doped lanthanum hexaaluminate.
- the construction according to the invention of the thermal barrier coating makes it possible to fully exploit the advantages of the intermediate layer, in particular consisting of lanthanum hexaaluminate, which is considerably more stable in sintering compared to zirconium oxide, while at the same time achieving high erosion resistance ensured by the outer cover layer.
- there is an additional phase boundary between the outer cover layer and the intermediate layer is formed. This acts as an impurity and significantly reduces heat conduction in the thermal barrier coating.
- the hafsite-forming layer applied to the metallic component is metallic and preferably formed as an aluminum diffusion layer or as a platinum-aluminum diffusion layer or as an MCrAlY coating layer.
- the adhesion-promoting layer increases the adhesion of the thermal barrier coating on the metallic component.
- the outer cover layer has a layer thickness between 1 and 250 .mu.m, in particular between 10 and 200 .mu.m
- the intermediate layer has a layer thickness between 30 and 2250 .mu.m, in particular between 50 and 2000 .mu.m
- the inner contact layer has a layer thickness between 1 and 2250 .mu.m, in particular between 1 and 2000 .mu.m
- the adhesion promoting layer has a layer thickness between 1 and 650 .mu.m, in particular between 1 and 500 .mu.m.
- a component according to the invention in particular a component of a gas turbine such as an aircraft engine, with a bonding layer applied to a metallic component surface and a heat-insulating layer at least partially applied to the adhesion-promoting layer consists of a metallic substrate and a heat-insulating layer according to the invention, at least partially applied to the metallic substrate, as in the preceding described.
- a correspondingly coated component due to the significant reduction in the thermal conductivity and also significantly increased erosion resistance of the thermal barrier coating according to the present invention, has a significantly lower wear rate with a correspondingly longer service life.
- the thermal barrier coating or its individual components and layers according to the invention are preferably applied to the component by thermal spraying or by a PVD (Physical Vapor Deposition) or EB-PVD (Electron Beam Physical Vapor Deposition) process or a CVD (Chemical Vapor Deposition) process applied.
- PVD Physical Vapor Deposition
- EB-PVD Electro Beam Physical Vapor Deposition
- CVD Chemical Vapor Deposition
- the figure shows a highly schematic of a metallic component 20 of a gas turbine, wherein an adhesive layer 18 is applied to a surface of the component 20.
- a heat-insulating layer 10 is applied to the adhesion-promoting layer 18, the thermal-insulating layer 10 comprising an inner contact layer 12, an intermediate layer 14 and an outer covering layer 16.
- the inner contact layer 12 and the cover layer 16 consist of a yttrium, yttrium oxide, calcium or magnesium partially stabilized zirconium oxide layer.
- the intermediate layer 14 is formed of lanthanum hexaaluminate according to the embodiment.
- the lanthanum hexaaluminate is preferably stabilized with magnesium or manganese.
- the thermal barrier coating 10 of metallic bonding layer 18 Due to the overall four-layer structure of the thermal barrier coating 10 of metallic bonding layer 18, the contact layer 16 of partially stabilized zirconia, the intermediate layer 14 of lanthanum hexaaluminate and the top layer 16 of partially stabilized zirconia is achieved that the thermal expansion coefficients between the individual layers are adapted to each other. Tensions within the thermal barrier coating 10 are thereby minimized.
