Definitions

  • the invention relates to a heat treatment of a porous ceramic coating to yield a segmentation and a device.
  • TBC thermal barrier coatings
  • the stationary temperature gradient can be higher than 1000 K/mm. Under transient conditions (heating up, shut down) with temperature rates >> 100 K/s the local temperature gradient can be much higher resulting in strains, which exceed the coating strain tolerance and lead to crack formation.
  • the focus for the development of TBC's with enhanced life is to increase and maintain the strain tolerance under high temperature exposure by keeping the thermal conductivity as low as possible.
  • the second pathway to reduce thermal stresses in the coatings is to try to adopt the columnar structure of the EB-PVD coatings, which has shown evidently its long life due to its unique architecture.
  • This, in thermal spraying, is succeeded with producing a Dense Vertical Cracked (or Segmented) microstructure.
  • the vertical cracks produced in the coating allow it to "balance" different strain rates along its thickness.
  • the disadvantage of this pathway is the higher effective thermal conductivity in thickness direction which has to be compensated by thicker coating.
  • the problem is solved by a method according to claim 1 and a device according to claim 4 and a component according to claim 6.
  • the idea of the present invention is to introduce vertical cracks in a porous coating after spraying.
  • the process is preferably based on a 8YSZ coating typically thermally sprayed on samples or components.
  • the coated component is subjected to a steady sintering stage under a controlled thermal gradient wherein the heat flow is directed from the surface of the coating to the substrate.
  • the heat sources can be lasers, high power lamps, hot gas burners, plasma guns or special designed ovens.
  • the surface temperature has to be monitored and used to control the heating power.
  • the surface temperature has to be high enough to initiate the sinter process of the coating within reasonable times (>1523K). To avoid phase transitions and melting an upper temperature limit has to be established as well.
  • the spacing of the vertical crack pattern is mainly determined by the coating stiffness, which depends on the exposure time and temperature level as well as on the cooling rate. By adjusting the time at temperature-gradient-exposure and cooling rate a well-defined vertical crack pattern or segmentation network with tuned spacing can be formed.
  • the figure 1 shows an inventive device 1.
  • the device 1 comprises at least an oven 10 in which several hollow components 7', 7", ..., 100 can be mounted on adapters 11', 11", ... which provide a cooling medium.
  • the cooling medium is especially provided by one or several tubes 4 which is especially air or any gas especially from outside the oven 10.
  • This cooling medium must not be at ambient temperature but can be heated too.
  • the heating on an outer side of the ceramic coating 70 can especially performed by laser beams.
  • a control unit 13 is used for regulating the cooling, the heating of the coating 70 and the temperature of the oven.
  • Figure 2 shows a component 100 which is an example for component 7', 7".
  • the component 100 has especially a metallic substrate 40 which is especially a nickel or cobalt based super alloy.
  • these substrate 40 several coatings like metallic bond coats (not shown, e. g. NiCoCrAlY) are present and at least an outer ceramic coating 70.
  • metallic bond coats e. g. NiCoCrAlY
  • the ceramic coating 70 is especially made of zirconia, especially 8YSZ, 48YSZ or a pyrochlore structure.
  • the ceramic coating 70 has a porosity of at least 3%, especially of at least 5% and maximum 15%, especially maximum 10%, very especially maximum 8%.
  • the ceramic coating 70 Before the heat treatment the ceramic coating 70 has no long, vertical cracks, wherein “vertical” means almost perpendicular to the outermost surface towards substrate 40 and “long” means at least 10% to 90% especially 20% to 80% of the thickness of the ceramic coating 70.
  • FIG 3 an enlarged view of the microstructure of the coating 70 is shown.
  • the ceramic coating 70 comprises some pores 75, wherein due to the thermal treatment in the oven 10 vertical cracks 77 were firstly developed, which start from the outermost surface of the coating 70.
  • the coating 70 was produced by a spraying method (APS, VPS, LPPS, HVOF, cold spray, ...) using powder grains. By the heat treatment the powder grains sinter together.
