- Plastics have over other materials such.
- alloys or ceramics the advantage of lower specific weight and better manufacturability and workability.
- Another object of the invention is to show a component, a coating and a sealing system which have a low weight and good mechanical properties and a high resistance to corrosion and erosion.
- the object is achieved by a component, a coating and sealing system, in particular made of a plastic with powder particles according to claim 15, 16 or 17.
- FIG. 8 shows a turbine blade
- Figure 9 is a gas turbine
- Figure 10 is a steam turbine.
- the material according to the invention consists of plastic, that is to say a polymer, in which powder particles 7 (FIG. 2), in particular nanoparticles, are distributed or embedded.
- the powder particles consist partly or completely of nanoparticles.
- plastic can be selected which appears expedient for the use of the component 1, for example polyimides, for example.
- polyimides for example.
- the polymers also include, for example, thermoplastics. An organic color with powder particles (for coloring) is not included in the invention.
- powder particles as constituents which are added to the plastic for coloring.
- the plastic according to the invention does not contain any fillers which undergo further reaction, for example to convert a monomer into a polymer, as is known from a 3M ESPE brochure, and does not include the case where the powder particles are a catalyst.
- the plastic powder particle mixture may, of course, be present in powdered form, wherein the plastic encloses the powder particles 7 or is mixed with the powder particles 7.
- the powder particles 7 are chemically inert and are, for example, round, oval or blocky (i.e., angular, cuboid, polyhedrons).
- the powder particles 7 represent a second phase in a matrix of plastic, i. consisting of a material other than the plastic, which represents the matrix, wherein the plastic in particular at least 50vol%, 60vol% or 70vol%, 80vol% or 90vol% of the plastic powder mixture and preferably has fractions between 50 to 90vol%, 50 to 80vol %, 60 to 90vol%, 50 to 70vol%, 60 to 80vol%, 80 to 90vol%, 50 to 60vol%, 60 to 70vol%, 70 to 80vol%, 80 to 90vol% or 90 to 99vol%.
- the plastic is not the holding together of powder particles, as z. B. of magnets is known, which consist of a plastic and magnetic or magnetizable powder particles.
- magnets which consist of a plastic and magnetic or magnetizable powder particles.
- strong magnets made of a brittle alloy break easily, so that powder particles which are held together only by the plastic, but which does not form the matrix.
- the nanoparticles have particle sizes of less than 500 nm, in particular less than 300 nm, 100 nm or 50 nm.
- the powder particles 7 may be made of metal, ceramic or other plastic and mixtures of metal, ceramic or plastic. Glass dust is not covered by the invention.
- the powder particles 7 may be embedded in the plastic or protrude from the plastic and optionally also form a large-area coating.
- a fiber-reinforced plastic (FC) with powder particles 7 is used.
- Hollow or solid components 1 can be produced from the plastic according to the invention, the powder particles 7 serving to increase the inherent component damping in the interior.
- FIG. 1 shows a component 1 according to the invention which, for example, is hollow and has a cavity 13.
- the plastic according to the invention forms an outer wall 4, 16 of the component 1.
- the powder particles 7 are distributed, for example, in the entire thickness of the front outer wall 4, which for example represents a leading edge 409 (FIG. 8) of a blade 120, 130 for a turbomachine, a compressor 105 or a turbine 100.
- the leading edge 409 or generally particularly stressed surface areas of a component 1 have the powder particles 7, because they improve the mechanical properties and / or the erosion properties of the plastic.
- the powder particles 7 may protrude from the surface 18 of the wall 4, so as to have the erosion properties or the To improve flow resistance of the component 1.
- the powder particles 7 can also be concentrated only in the near-surface region 10.
- the mechanical and erosive loads are lower, so that either powder particles or only in the near-surface region 10 of the wall 16 powder particles 7 are mixed.
- the powder particles 7 can therefore occur locally distributed in the plastic, so their concentration can have a Gradien- th.
- the blade 120, 130 may be used for wind turbines, compressors 105, pumps, steam 300, 303 (FIG. 7) or gas turbines 100 (FIG. 9) or steam turbines (FIG. 10) of any size.
- the use of the lightweight plastic compared to steel or other metallic materials results in a significant weight reduction, such that the rotor 103 (FIG. 9) of a steam 300, 303 or gas turbine 100, although larger in size , can be lighter, so the efficiency increases and a fast startup and shutdown is possible.
- FIG. 3 shows a solid component 1, for example a turbine blade 120, 130.
- the powder particles 7 can be distributed homogeneously (FIG. 2) or, as shown in FIG. 3, are present only in the edge regions 10 in which a high mechanical and / or erosive load occurs. In the case of a turbine blade these are the leading edge 409 and the blade tip 415.
- the component 1 can also be a hybrid component (FIG. 4), ie the plastic according to the invention is still connected to a component piece made of a different material.
- the blade leaf 406, in particular the entire surface of the blade leaf 406, consists of the plastic according to the invention and the blade root 183 (FIG. 8) consists of metal.
- FIG. 5 shows a component 1, for example a blade of a compressor 105, which, for protection against corrosion and / or erosion, has a coating 25 made of a plastic, optionally fiber-reinforced, in particular of a plastic with the powder particles 7.
- the powder particles 7 may have a local gradient and / or protrude from the surface with respect to their distribution over the component cross-section.
- FIG. 6 shows a part of an exemplary sealing system 31.
- the sealing system 31 consists of at least one rotor blade 120, which moves in the circumferential direction 34.
- a sealing coating 22 made of a plastic, optionally fiber-reinforced, in particular made of a plastic powder particles 7 applied, which seals the blade 120 relative to a housing 19.
- the blade 120 may consist of the commercially available materials, in particular of steel or iron alloys for blades of a compressor 105 or turbine blades of a steam turbine. Plastic coatings are easy to remove and re-apply.
- a sealing coating 22 made of plastic may be present both on the housing 19 and on the blade tip 415.
- the blade 120 can also consist of solid plastic according to FIG. 1, 3 or 4.
- FIG. 8 shows a perspective view of a moving blade 120 or guide blade 130 of a turbomachine that extends along a longitudinal axis 121.
- the turbomachine may be a gas turbine 100 of an aircraft or a power plant for power generation, a steam turbine 300, 303 or a compressor.
- the blade 120, 130 has, along the longitudinal axis 121, successively a fastening region 400, for example a blade platform 403 adjacent thereto and an airfoil 406.
- the blade 130 may have at its blade tip 415 another platform (not shown).
- a blade root 183 is formed, which serves for attachment of the blades 120, 130 to a shaft or a disc (not shown).
- the blade root 183 is designed, for example, as a hammer head. Other designs as Christmas tree or Schwalbenschwanzfuß are possible.
- the blade 120, 130 has a leading edge 409 and a trailing edge 412 for a medium flowing past the airfoil 406.
- the metallic part of the blade 120, 130 can in this case be produced by a casting process, also by directional solidification, by a forging process, by a milling process or combinations thereof.
- the blade 120, 130 may be hollow or solid.

- the steam turbine has a high-pressure turbine section 300 and a medium-pressure turbine section 303, each having an inner housing 312 and an outer housing 315 enclosing this.
- the high-pressure turbine part 300 is designed, for example, in Topfbauart.
- the medium-pressure turbine section 303 is double-flow. It is also possible for the medium-pressure turbine section 303 to be single-flow.
- a bearing 318 is arranged between the high-pressure turbine section 300 and the medium-pressure turbine section 303, the turbine shaft 309 having a bearing region 321 in the bearing 318.
- the turbine shaft 309 is supported on another bearing 324 adjacent to the high pressure turbine sub 300.
- the high-pressure turbine section 300 has a shaft seal 345.
- the turbine shaft 309 is sealed from the outer housing 315 of the medium-pressure turbine section 303 by two further shaft seals 345.
- the turbine shaft 309 in the high-pressure turbine part 300 has the high-pressure blading 354, 357, for example, of the plastic according to the invention in the blade row, which must withstand the temperature that is possible Operating temperatures is compatible.
- the middle-pressure blast turbine 303 has a central steam inlet region 333.
- the turbine shaft 309 has a radially symmetrical shaft shield 363, a cover plate, on the one hand for dividing the steam flow into the two flows of the medium-pressure turbine section 303 and for preventing direct contact of the hot steam with the turbine shaft 309.
- the turbine shaft 309 has in the medium-pressure turbine section 303 a second blading area 366 with the medium-pressure blades 354, 342.
- the hot steam flowing through the second blading area 366 flows out of the medium-pressure turbine section 303 from a discharge connection 369 to a downstream low-pressure turbine, not shown.
