Definitions

  • the invention relates to alloys and metallic components comprising particles of quasicrystals, to a method of production and to coating systems.
  • Particle reinforcement is a known mechanism for improving the mechanical properties of metals or metallic alloys.
  • the prior art is to achieve such particle reinforcement by ceramic particles, which can also achieve an increase in strength due to the different coefficients of thermal expansion and the stresses initiated thereby, but can also initiate cracks if the thermal stresses become too great, in particular if the component is used with such an alloy at high temperatures and is exposed to thermal temperature gradients.
  • the object is achieved by an alloy according to claim 1, a powder according to claim 5, a component according to claim 6 and a method according to claim 10 or 13 and a layer system according to claim 14, 15.
  • QKP quasi-crystal particles
  • Quasicrystals have properties that are adjustable between those of metals and ceramics.
  • the thermal expansion coefficient may be close to metals, which minimizes thermal stresses between metal matrix and QKP during operation.
  • the QCPs stabilize the metallic microstructure and help the material to reach higher failure voltages. Abrasive properties also improve with the introduction of QKP. Since quasicrystals have poor heat conduction, near-surface QCPs can also be used for thermal insulation, although this does not have to be understood as a layer with its problem of spalling, but rather as a gradual concentration gradient of the QCP.
  • FIG. 1 schematically a component 1, 120, 130 is shown, which was made of a metallic alloy or metal.
  • the component 1, 120, 130 can also be made of a powder comprising a metal alloy with quasi-crystals.
  • the quasi-crystal particles are present only in the near-surface region 7 of the component 1 ', 120, 130, when the greatest stresses or strains occur there.
  • the quasi-crystal particle (QKP) has. These may be mechanically more heavily loaded areas of the component. For turbine blades 120, 130 this is eg the leading edge.
  • the elements can replace Ni with Pd or Ru or / and Co with Fe or Mn.
  • the listed QC types offer good flexibility to realize the proposed particle-based quasicrystalline layer systems and to adapt them to the individual requirements of the component.
  • FIG. 4 shows a perspective view of a blade 120 or guide vane 130 of a turbomachine, which extends along a longitudinal axis 121.
  • the turbomachine may be a gas turbine of an aircraft or a power plant for power generation, a steam turbine or a compressor.
  • the blade 120, 130 has along the longitudinal axis 121 consecutively a fastening region 400, a blade platform 403 adjacent thereto and an airfoil 406 and a blade tip 415.
  • 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.
  • blades 120, 130 for example, solid metallic materials, in particular superalloys, are used in all regions 400, 403, 406 of the blade 120, 130.
  • Such superalloys are for example from EP 1 204 776 B1 .
  • EP 1 306 454 .
  • the blade 120, 130 can be made by a casting process, also by directional solidification, by a forging process, by a milling process or combinations thereof.
  • the blades 120, 130 may have coatings against corrosion or oxidation, e.g. M is at least one element of the group iron (Fe), cobalt (Co), nickel (Ni), X is an active element and stands for yttrium (Y) and / or silicon and / or at least one element of the rare ones Earth, or hafnium (Hf)).
  • M is at least one element of the group iron (Fe), cobalt (Co), nickel (Ni)
  • X is an active element and stands for yttrium (Y) and / or silicon and / or at least one element of the rare ones Earth, or hafnium (Hf)).
  • Such alloys are known from the EP 0 486 489 B1 .
  • EP 0 412 397 B1 or EP 1 306 454 A1 The density is preferably 95% of the theoretical density.
  • the layer composition comprises Co-30Ni-28Cr-8Al-0.6Y-0.7Si or Co-28Ni-24Cr-10Al-0.6Y.
  • nickel-based protective layers such as Ni-10Cr-12Al-0.6Y-3Re or Ni-12Co-21Cr-11Al-0.4Y-2Re or Ni-25Co-17Cr-10Al-0.4Y-1 are also preferably used , 5RE.
  • thermal barrier coating which is preferably the outermost layer, and consists for example of ZrO 2 , Y 2 O 3 -ZrO 2 , ie it is not, partially or completely stabilized by yttria and / or calcium oxide and / or magnesium oxide.
  • the thermal barrier coating covers the entire MCrAlX layer.
  • suitable coating processes such as electron beam evaporation (EB-PVD)
  • stalk-shaped grains are produced in the thermal barrier coating.
  • Other coating methods are conceivable, for example atmospheric plasma spraying (APS), LPPS, VPS or CVD.
  • the thermal barrier coating may have porous, micro- or macro-cracked grains for better thermal shock resistance.
  • the thermal barrier coating is therefore preferably more porous than the MCrAlX layer.
  • Refurbishment means that components 120, 130 may have to be freed of protective layers after use (eg by sandblasting). This is followed by removal of the corrosion and / or oxidation layers or products. Optionally, even cracks in the component 120, 130 are repaired. Thereafter, a recoating occurs of the component 120, 130 and a renewed use of the component 120, 130.
  • the blade 120, 130 may be hollow or solid. If the blade 120, 130 is to be cooled, it is hollow and may still film cooling holes 418 (indicated by dashed lines) on.
