Definitions

  • the invention relates to a covering device for the coating of components via cold kinetic compaction and a method for coating components via cold kinetic compaction.
  • Coating components of a turbomachine via cold kinetic compaction or kinetic cold gas spraying is already known from practice, wherein, in this case, a coating is applied to a to-be-coated component in that particles of a coating material are directed at a to-be-coated surface of the component that is being coated with the aid of a carrier gas.
  • a flat coating of the surface of the component being coated is always being carried out.
  • the not-to-be-coated region of the surface of the to-be-coated component must be covered with the aid of a covering device.
  • Covering devices which can be used to cover the regions of the surface that are not to be coated, are already known for coating methods such as thermal spraying. These covering devices for thermal spraying that are known from the prior art are not suitable, however, for use when coating components via cold kinetic compaction. Thus, the covering devices known from practice would themselves be coated and had to be disposed of after the coating process.
  • the object of the present invention is creating a novel covering device for the coating of components via cold kinetic compaction or kinetic cold gas spraying and a method for coating components.
  • the covering device is profiled such that it encloses such an acute angle with that region of the surface which is to be covered by same and therefore is not to be coated, that particles of a coating material can be deflected from the component such that the particles do not adhere to the covering device.
  • the covering device according to the invention is suitable especially for the coating of sections of components via cold kinetic compaction or kinetic cold gas spraying.
  • the covering device according to the invention there is no danger that the covering device itself will be coated by the coating material.
  • covering devices that have been adapted true-to-contour can be used multiple times.
  • FIG. 1 is first embodiment of a covering device according to the invention for the coating of components via cold kinetic compaction or kinetic cold gas spraying;
  • FIG. 2 is a second embodiment of a covering device according to the invention for the coating of components via cold kinetic compaction or kinetic cold gas spraying.
  • the present invention relates to the coating of components, particularly components of a gas turbine, via cold kinetic compaction or kinetic cold gas spraying.
  • particles of a coating material are applied to form the coating on the component with the aid of a carrier gas, namely on a to-be-coated surface of the component.
  • FIG. 1 shows a rough diagram of a component 10 to be coated via cold kinetic compaction or kinetic cold gas spraying, wherein the to-be-coated component 10 is supposed to be coated in a first region 11 of a surface and not to be coated in a second region 12 of the surface.
  • the region 12 of the surface of the component 10 that is not supposed to be coated can be covered with a covering device 13 according to the invention, wherein the inventive covering device 13 is profiled such that it encloses such an acute angle with that region 12 of the surface of the component which is to be covered by same and therefore is not to be coated, that particles of a coating material can be deflected from the component 10 such that the particles do not adhere to the covering device 13 .
  • the covering device 13 is profiled in a zigzag shape, wherein first sections 14 enclose a right angle with the not-to-be-coated region 12 of the surface of the component 10 , and wherein second sections 15 of the covering device 13 , which are respectively positioned between two adjacent first sections 14 , enclose a smaller angle with the not-to-be-coated region 12 of the surface of the component 10 , which is at least 30°, however.
  • This makes it possible to guarantee that particles of a coating material, which are directed at the surface of the component 10 at a right angle, ricochet off the second sections 15 of the covering device 13 according to the invention and are thereby deflected from the component 10 .
  • Neither the not-to-be-coated region 12 of the surface of the component 11 nor the covering device 13 are coated in the process so that it is possible to use the covering device as frequently as desired.
  • the covering device is fabricated of a hard material, e.g., of a metallic material or a hard plastic.
  • FIG. 2 shows the to-be-coated component 10 with a covering device 16 according to a second exemplary embodiment of the present invention, wherein the covering device 16 is profiled in turn in a zigzag shape just like the covering device 13 .
  • the covering device has first sections 17 , which enclose an angle of between 30° and 90° with the not-to-be-coated region 12 of the surface of the component.
  • Second sections 18 which are positioned respectively between two adjacent first sections 17 of the covering device 13 , enclose a smaller angle with the not-to-be-coated region 12 of the surface of the component 10 , namely an angle of at least 30°.
  • depressions 19 of the covering device 16 according to the invention which are configured between the first sections 17 and the second sections 18 of the covering device, are completely covered in the transport direction of the coating material during cold kinetic compaction so that no particles whatsoever of the coating material can reach the region of the depression 19 .
  • the depressions 19 are thus situated in a so-called “shadow of the spray” during cold kinetic compaction so that there is no danger whatsoever that the depressions 19 of the covering device 16 will be coated.
