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.
  • the system comprises 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.
  • 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 7 especially a metallic bond coat 7 and very especially a NiCoCrAlY-based bond coat 7 is applied on.
  • the bond coat 7 reveals an engineered surface, here in the form of bumps 24.
  • the engineered surface or bumps 24 are yielded during coating by additional means or working the bond coat 7 after having fully coated the bond coat 7 and can have any geometry.
  • the bumps 24 are not caused by the roughness of the bond coat 7.
  • TGO thermally grown oxide layer
  • 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.
  • 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 or mixtures as known by the state of the art.
  • yttrium Y
  • Y yttrium
  • the engravings 16 are especially made by a laser.
