Definitions
- the invention relates to a component according to the preamble of claims 1 and 3.
- Turbine blades in particular for gas turbines, are coated in particular in the airfoil area because they are exposed to high thermal loads.
- the object of the invention is therefore to show a masking layer which, after a desired coating of the turbine blade, can be easily removed again in the undesired areas without affecting the
- Base material or the geometry of the turbine blade comes in the masked area.
- a ceramic is applied directly to the base material of the turbine blade.
- Thermal insulation layers that are applied to a turbine blade in the airfoil area generally have intermediate layers between a substrate, ie the base material of the turbine blade, and the thermal insulation layer, such as so-called adhesive layers, for example metallic MCrAlY, or diffusion barriers. These intermediate layers are dispensed with during masking in order to prevent a good connection of the masking layer.
- the masking layer is in particular made of ceramic because the brittle ceramic can be removed by simple methods such as sandblasting or dry ice blasting.
- the material for the ceramic is chosen so that there is little or no diffusion from the ceramic into the substrate.
- the object of the invention is further achieved by a turbine blade according to claim 3.
- the masking layer reacts with the material of the material to be applied, making it easy to remove.
- FIG. 1 shows a turbine blade according to the prior art
- FIG. 2 process steps for producing a coating according to the prior art
- Figure 3 shows a masking layer of an inventive
- FIG. 4 shows a further masking layer of a turbine blade according to the invention
- FIGS. 7 and 8 show how the masking layer can be easily removed again after a reaction.
- FIG. 1 shows a perspective view of a turbine blade 1, in particular a rotor blade for a gas turbine, which extends along a longitudinal axis 4.
- the turbine blade 1 has, in succession along the longitudinal axis 4, a fastening region 7, an adjacent blade platform 10 and an airfoil region 13.
- the fastening area 7 is designed as a blade root 16, which serves to fasten the turbine blade 1 to a shaft, not shown in more detail, of a turbomachine, also not shown.
- the blade root 16 is designed, for example, as a hammer head. Other configurations, for example as a fir tree or dovetail foot, are possible.
- solid metallic materials in particular nickel- or cobalt-based superalloys, are used in all areas of the turbine blade.
- the turbine blade can be manufactured by a casting process, a forging process, a milling process or combinations thereof.
- the fastening area 7 is made of metal, because it is clamped into a corresponding shape of a pane with a precise fit. Brittle ceramic coatings would flake off and change the geometry in the fastening area.
- the airfoil area 13 is coated, for example, with a heat insulation layer, it being possible for further layers, such as, for example, adhesion promoter layers (MCrAlY layers), to be arranged between the base material of the turbine blade 1.
- MrAlY layers adhesion promoter layers
- a component according to the invention in the form of a turbine blade 1 can be a guide or rotor blade of any turbine, in particular a steam or gas turbine.
- FIG. 2 shows what happens when the surface of the blade 1 has no masking layer 25 (FIG. 3).
- the material 22 of an intermediate layer 19 (MCrAlY), which has been applied to a surface of the turbine blade 1 and forms the intermediate layer 19, for example by plasma spraying, by PVD or CVD or immersion in a liquid metal or application of powder in any form, and leads to a reaction of the material 22 with the turbine blade 1 and for good adhesion of the intermediate layer 19 with the base material of the turbine blade 1.
- FIG. 3 shows a component according to the invention in the form of a turbine blade 1 with a masking layer 25.
- a first functional layer 28 is first applied to the turbine blade 1.
- This is, for example, a nanometer-thin polycarbosilane layer that crosslinks in air at 200 ° C. and enables good adhesion to the base material 40 of the turbine blade 1.
- a gradient layer 31 is applied to the first functional layer 28, the material for the gradient layer 31 being a mixture of polysiloxane and a metal ceramic and / or metal.
- the gradient layer 31 can, for example, in the form of a
- slips with layer thicknesses of 10 - 30 ⁇ m thickness are applied and also crosslinked in air at about 200 ° C.
- a further powder in particular the composition MCrAlY, where M stands for Fe, Co, Ni, is added to this material of the gradient layer 31 because, due to its expansion coefficient, it is used as an intermediate layer (adhesion promoter layer) between the base material 40 and the ceramic thermal insulation layer.
- a reactive layer 34 is applied to the gradient layer, which consists, for example, of a pure carbon precursor.
- the crosslinking within the reactive layer 34 takes place at 180 ° C. in air.
- the crosslinked layers 28, 31, 34 are converted into a ceramic by a thermal treatment at 1000 ° C. in an argon atmosphere, using the so-called pyrolysis process. Due to the change in density of the organometallic precursor such as, for example, the polysiloxane with a density of 1 g / cm 3 in a silicon oxycabid phase (SiOC) with a density of approx.
- the organometallic precursor such as, for example, the polysiloxane with a density of 1 g / cm 3 in a silicon oxycabid phase (SiOC) with a density of approx.
- a material 22 is applied to the airfoil area 13 of the turbine blade 1 and to the masking layer 25.
- the material 22 reacts with the reactive layer 34 to form a reaction layer 43, i.e. to a material that is resistant to high temperatures, but is, for example, soluble in water, i.e. easily removable.
- the material 22 is, for example, aluminum, which is applied to the turbine blade 1 to form an aluminide layer.
- an aluminide layer can be applied by plasma spraying or by methods as specified in EP patent 0 525 545 B1 and EP patent 0 861 919 B1.
- the carbon of the reactive layer 34 reacts with aluminum to form Al 4 C 3 . If the airfoil region 13 is completely coated, the entire airfoil, in particular the fastening region 7, can be introduced into water, as a result of which the water-soluble reaction layer 43 converted with the material 22 dissolves.
- the underlying layers 28, 31 can easily be removed by dry ice blasting, so that the geometry of the fastening area 7 is not changed by the removal method.
- Aluminum is used for example in refurbishment, i.e. et al when removing used MCrAlY layers, applied to a turbine blade 1.
- the masking layer 25 can also be a gradient layer which has a gradual structure, that is, the composition on the substrate 40 is selected so that good adhesion is possible, and on the outer surface the composition is such that it reacts with the material 22 of layers still to be applied.
- FIG. 4 shows a component according to the invention in the form of a turbine blade 1 with a masking layer 25.
- a ceramic layer 37, which forms the masking layer 25, is applied directly to the metallic turbine blade 1, for example.
- This can, for example, be an oxide ceramic that is adapted to the thermal expansion coefficient of the substrate.
- the dense ceramic layer 37 also forms during a coating process of the turbine blade 1 with different layers, e.g. Adhesion promoter layers or thermal insulation layers, a diff barrier.
- the masking layer 25 can also only react with the material 22 of layers still to be applied, for example to form a brittle layer 43, for example a ceramic layer 37.
- the ceramic layer 37 can, for example, also only form after a further heat treatment (pyrolysis).
- Such brittle layers 43 can be removed by simple processes such as thermal shock processes or sandblasting or dry ice blasting, ie by energy-introducing, but not abrasive, blasting processes. It is particularly advantageous if the masking layer 25 reacts with the material 22 of layers to be applied to form a water-soluble layer 43.
- Masking layer further layers may be present, i.e. the masking layer 25 can be constructed in multiple layers.
- the masking layer 25 can be constructed in multiple layers.
- FIG. 5 shows a turbine blade 1 with a substrate 40, on which a masking layer 25 is applied.
- the material of the masking layer does not react and diffuse at the higher temperatures of the
- material 22 hits and reacts with the masking layer 25.
- the reaction can also take place in a downstream heat treatment if the reaction temperature is higher than the substrate temperature during the coating.
- the reaction layer 43 (FIG. 6) formed in this way can easily be removed again after the coating process of the turbine blade, because it is, for example, brittle or water-soluble.
- the material 22 thus also strikes the unmasked areas of the substrate 40 of the turbine blade 1 and forms a desired coating 55 (FIG. 6).
- FIG. 7 shows a water bath 46 in which a turbine blade with a water-soluble layer 43 is introduced.
- the water solubility can be easily removed from the layer 43, so that after the turbine blade 1 has been removed from the water bath, an uncoated part and a desired coated part 55 of the turbine blade 1 are present.
- the reaction layer 43 can also by
- the brittle reaction layer 43 can be removed by an energy input from an irradiation cannon 49 (ultrasound, dry ice blaster, sand blaster). (Fig. 8)
