Definitions

  • the invention relates to the use of a spray compacting plant to create a layer and a layer system, that can be produced using a spray compacting system and is a layer system with a layer with undercuts according to claims 1, 2 and 3.
  • Coatings of components e.g. Bond layers or Thermal insulation layers of components exposed to high temperatures, such as. Gas turbine components are often made using plasma spraying coated, as in U.S. Patent 3,839,618 or U.S. Patent 4,447,466.
  • a spray compacting method is known from US Pat. No. 4,418,124 known, in which massive bodies are made.
  • the object of the present invention is to simplify Way layers with improved adhesion, in particular to be able to produce thick layers.
  • the task is solved by using a spray compacting system according to claim 1 and a layer system according to Claim 2 and Claim 3.
  • Figure 1 shows a spray compacting plant 1 used to at least one layer 16 according to the invention (FIG. 2) to produce on a substrate 30 ( Figure 2), the Layer 16, which can also be an intermediate layer 16 should adhere to the substrate 30.
  • a nozzle 4 melted, for example.
  • the molten particles 7 are not injected into a mold, where they should form a massive body, but form a layer 16 on a component 10.
  • the microstructure of the layer can be determined by the process parameters the spray compacting system can be set. So can target the porosity and / or undercuts can be set.
  • FIG. 2 shows a cross section through a layer system 28 of a component 1, which in a spray compacting plant 1 has been manufactured.
  • An intermediate layer 16 is present on the component 1 has been produced by spray compacting.
  • the intermediate layer 16 can be dense but, by appropriate variation of the process parameters, can also have a porous structure, possibly with undercuts 22, which enable better anchoring of a layer 19 applied to the layer 16 compared to a layer without undercuts and / or pores.
  • the improved adhesion is achieved not only by the undercuts 22, but also by the increased contact area between the layers 16 and 19.
  • Such layers 16 with undercuts 22 can also be used other methods (plasma spraying, CVD; PVD) become.
  • Layer 19 can, but does not have to, in a spray compacting plant 1 have been produced.
  • the component 10 is a turbine blade or generally a component 10 that is exposed to high temperatures and whose substrate 30 consists, for example, of a nickel- or cobalt-based superalloy.
  • Layer 16 is a so-called intermediate layer of the composition MCrAlY, where M stands for an element from the group iron, nickel or cobalt.
  • Layer 19 can be an anchoring layer or ceramic thermal barrier coating.
  • FIG. 3 shows a layer system 28 which has only one layer 16.
  • Layer 16 has a low porosity and is, for example, at least 0.5 mm thick. Such thick layers can be produced particularly well by means of a spray compacting system 1.
