Definitions

  • the invention relates to a ceramic layer-system with partially and fully stabilized zirconia which has also a dense vertical cracked microstructure (DVC).
  • DVC dense vertical cracked microstructure
  • TBC Thermal Barrier Coatings
  • the task of the invention is therefore to solve the problems given above.
  • DVC Dense Vertical Cracked
  • the system consists of partially stabilized zirconia, especially 8YSZ as the high fracture toughness lower layer to accommodate the CTE mismatch with bond coat and TGO and a lower toughness upper layer of fully stabilized zirconia, especially 48YSZ to provide the high temperature capability.
  • partially stabilized zirconia especially 8YSZ as the high fracture toughness lower layer to accommodate the CTE mismatch with bond coat and TGO
  • a lower toughness upper layer of fully stabilized zirconia especially 48YSZ to provide the high temperature capability.
  • the similar chemistry between the two coatings enhances their bonding.
  • DVC PSZ Appropriate preheating of the DVC PSZ will prepare its surface to receive the fully molten particles of FSZ and due to the high local temperatures during spraying allow diffusion between the two similar materials. Ideally 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 preferably 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 75 ⁇ m - 800 ⁇ m.
  • the porosity of the partially stabilized zirconia 10 is preferably 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
  • FSZ fully stabilized zirconia
  • 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 preferable between 50 ⁇ m - 800 ⁇ m.
  • 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.
