Definitions

  • the present invention relates to a method for coating a component with at least one opening and / or bore, in particular for coating components of a gas turbine or an aircraft engine.
  • protective layers are provided with protective layers. These are in particular corrosion, oxidation and wear protection layers of metallic and / or ceramic materials. Such protective layers are applied in particular by thermal spraying. For components with openings or holes, such. B. in blades of gas turbines with cooling air holes results in the thermal spraying of protective layers, however, the problem that the openings and / or holes are closed in the manufacture of new parts or after repair by the applied spray process. The subsequent exposure and reworking of the openings and / or holes is possible only with a very high and costly work.
  • An inventive method for coating a component having at least one opening and / or bore in particular for coating components of a gas turbine or an aircraft engine is inventively characterized in that the coating of the component at least in the region of the opening and / or the bore by means of a cold gas spraying process takes place and the component is aligned approximately perpendicular to the beam direction of the applied and the coating forming particles.
  • the use according to the invention of the cold gas spraying method also referred to as kinetic cold gas compacting, permits reliable and cost-effective coating of components with openings and / or bores since the accelerated particles adhere only at an approximately vertical spraying angle and thus openings and / or bores in the component only very little or can not close.
  • the possibility of using sprayed protective layers on components having openings and / or bores can be carried out inexpensively by the method according to the invention, so that there is also an extension of the service life and the operational safety of the corresponding component.
  • the component may be a blade of a rotor of a gas turbine or an aircraft engine with at least one cooling air bore.
  • the method according to the invention can be used advantageously, since the accelerated particles of the material forming the protective layer only very little or do not adhere to the generally oblique cooling-air bores. A closure of these cooling air bores by the mentioned particles is thus almost impossible to exclude.
  • a further advantage of the method according to the invention lies in the use of small beam cross sections, by means of which an extremely exact coating of the corresponding components is made possible.
  • an erosion and / or corrosion and / or oxidation and / or wear protection layer or a thermal barrier coating is formed by the coating.
  • the pulverulent particles to be applied at high speed and forming the protective layer may be composed of a metal, a metal alloy, a metal mixture, a metal-ceramic mixture and / or a mixture of a metal alloy with ceramic.
  • consist mik. So z. B. consist of the titanium nitride particles for the formation of an erosion control layer.
  • the temperature of the particles during cold gas spraying is between room temperature and 800 ° C.
  • the powdery particles are applied to the component or component surface in a solid or doughy state and adhere to it.

  • Typical speeds of the particles during cold gas spraying are about 500 to 1,500 m / s.
  • the erf ⁇ ndungswele method has the advantage that the cold gas injection method has a high spray efficiency with little splash loss, so that a coverage of non-coated areas of the component is almost not required.
