Definitions
- the invention relates to a ceramic layer-system with par- tially and fully stabilized zirconia which has also a dense vertical cracked microstructure (DVC) .
- DVC dense vertical cracked microstructure
- TBC Thermal Barrier Coatings
- Coating life Thermal Spray porous coatings do not demon ⁇ strate at the same level the high strain tolerance along the coating thickness which can be seen in other coating types such as EB-PVD.
- the thermal barrier coatings porosity has been increased to improve strain tolerance. However as mentioned above, that can reduce the spray ability process window and influence negatively the cohesion and erosion resistance of the coat ⁇ ings . 4) YSZ for TBC chemistries are currently limited to 1528K maximum temperature due to phase transformation issues.
- New chemistries have been adopted that present phase stabil ⁇ ity in higher temperatures. However they show significantly lower fracture toughness compared to the partially stabilized zirconia and it is certain that their erosion resistance will be even less.
- the task of the invention is therefore to solve the problems given above .
- DVC Dense Vertical Cracked
- DVC coatings have increased cohesion and adhesion compared to the typical porous coatings. The reason is that a very high ratio of fully molten particles deposit on hot substrate or hot previously deposited splats which promotes a good in ⁇ timate bonding to develop between them. Improved adhesion re- quires high energy for a horizontal crack to propagate so that guarantees a lower delamination .
- the system consists of partially stabilized zirconia, espe ⁇ cially 8YSZ as the high fracture toughness lower layer to ac ⁇ commodate the CTE mismatch with bond coat and TGO and a lower toughness upper layer of fully stabilized zirconia, espe ⁇ cially 48YSZ to provide the high temperature capability.
- the similar chemistry between the two coatings enhances their bonding.
- Appropriate preheating of the DVC PSZ will prepare its sur ⁇ face to receive the fully molten particles of FSZ and due to the high local temperatures during spraying allow diffusion between the two similar materials.
- a number of the vertical cracks will progress from one coating to the other demonstrating the continuity between the two coatings. In this manner the interface which has shown to be the weakest link in other bi-layer systems will be reinforced.
- the figure shows a layer system 1.
- the layer system 1 comprises a substrate 4 which is prefera- bly metallic and very preferably made of a nickel or cobalt based super alloy.
- a bond coat especially a metallic bond coat 7 and very especially a NiCoCrAlY-based bond coat 7 is applied on.
- TGO thermally grown oxide
- first zirconia layer 10 made of a partially stabilized zirconia.
- the thickness of the partially stabilized zirconia layer 10 is preferable between 75ym - 800ym.
- the porosity of the partially stabilized zirconia 10 is pref ⁇ erably lower than 5% and very preferably lower than 3%.
- a fully stabilized zirconia layer 13 which is especially the outer most layer of the layer system 1.
- This outer layer can also be made of a pyrochlore ceramic, such as gadolinium zirconate (GZO) , which partially or fully replaces the fully stabilized zirconia (FSZ) .
- GZO gadolinium zirconate
- the porosity of the fully stabilized zirconia 13 is lower than 5% and preferably lower than 3%.
- the thickness of the fully stabilized zirconia 13 is prefera ⁇ ble between 50ym - 800ym.
- the stabilization in this zirconia based system can be reached by yttria or by any other rare earth element as known by the state of the art or by a combination of that.
- yttrium is used for stabilization.
