Definitions

  • the invention relates to a method for cold gas spraying according to the preamble of claim 1. Furthermore, the invention relates to a device for cold gas spraying according to the preamble of claim 6.
  • Modern gas turbines in particular aircraft engines, must meet the highest demands in terms of reliability, weight, performance, economy and service life.
  • aircraft engines have been developed, especially in the civil sector, which fully meet the above requirements and have achieved a high degree of technical perfection.
  • the most important materials used today for aircraft engines or other gas turbines are titanium alloys, nickel alloys and high-strength steels.
  • the high strength steels are used for shaft parts, gear parts, compressor casings and turbine casings.
  • Titanium alloys are typical materials for compressor parts.
  • Nickel alloys are suitable for the hot parts of the aircraft engine.
  • gas turbine components made of titanium alloys nickel alloy or other alloys are known from the prior art primarily investment casting and forging. All highly stressed gas turbine components, such as the blades for a compressor, are forgings. Blades and vanes of the turbine, however, are usually designed as precision castings.

  • the kinetic cold gas spraying is to be carried out using brittle metals as the coating material
  • high layer porosities occur in the forming coating.
  • Ceramic coating materials can be partially used in cold gas spraying. not be used at all. There is therefore a need for a method and a device for cold gas spraying, with which also coating materials made of brittle metals and ceramics can be used well for the coating of components.
  • the present invention is based on the problem of proposing a novel method for cold gas spraying and a corresponding device.
  • Preheating particles of a coating material before they are supplied to the spray gun This makes it possible to process even brittle metals and ceramics as coating materials safely and reliably during cold gas spraying.
  • the device according to the invention for cold gas spraying is defined in claim 6.

  • the particles of a special coating material are heated to a temperature adapted to this special coating material.
  • Fig. 2 shows an embodiment of the invention, which substantially corresponds to the embodiment of Fig. 1, so to avoid unnecessary repetition for the same components same reference numerals are used.
  • the exemplary embodiment of FIG. 2 differs from the exemplary embodiment of FIG. 1 only in that particles of three different coating materials are fed to the mixing device 13, for which purpose the device of FIG. 2 comprises a third particle conveyor 16.
  • the third particles of the third coating material which are provided by means of the third particle conveyor 16, but subjected to no preheating, but rather only the first particles of the first particle material and the second particles of the second particle material, which the particle conveyors 11, 12 of the spray gun 10 are provided.
  • the invention is particularly suitable for coating workpieces with coating materials of brittle metals or ceramics.
  • the invention finds use in coating workpieces with Ti6A14V.

Abstract

L'invention concerne un procédé de pulvérisation gazeuse à froid. Des particules d'au moins un matériau de revêtement sont envoyées avec un gaz porteur sur la surface d'une pièce à revêtir, à l'aide d'un pistolet de pulvérisation. Selon l'invention, les particules d'au moins un matériau de revêtement sont préchauffées.
