Definitions
- the invention relates to a method for producing an armor for a metallic Component that is provided on its surface.
- Armorings or brushed coverings are e.g. on engine components, e.g. Sealing tips of labyrinth seals or blade tips, provided to their To counteract processing during brushing operations during operation. Since the Efficiency of a compressor or turbine largely depends on the gap size depends between the rotating and the standing component, it will be with increasing processing, e.g. the blade tips, reduced.
- the armor usually works its way into an intake lining when the engine is operating an opposite, second component.
- Such run-in coverings are abradable and mostly consist of a corrosion and erosion-resistant layer. Armoring of the engine component is particularly necessary if the Strength and hardness of the run-in coatings to increase erosion and temperature resistance is increased and the processing of the engine components additionally reinforced.
- the armor ensures that the brushing process is minimal Gap is formed between the armor and the intake coating.
- an MCrAlY powder is used applied by galvanic application to the component to be armored, whereby the necessary hard particles in the bath, e.g. BN, are included.
- This Particles are etched free after application.
- Such a process is expensive and complex.
- the subsequent etching is due to the lack Environmental compatibility and the necessary covering of the component disadvantageous.
- a contour adapted to the component contour is used
- the solder foil is attached to the component by gluing or the like.
- BN particles are in the solder foil inserted.
- the solder foil is then melted by heat treatment and the BN particles embedded in it.
- This procedure is also proportional expensive and complex.
- the connection between the particles and the component is insufficient.
- JP 55-82765 A it is known that consisting of a Ni or Co base alloy Substrate first with a mixture of ceramic, aluminum and metal powder to coat to ensure the heat resistance of the long-term high temperature exposure Improve layer. This is followed by a layer of one with one Binder-provided Ni powder, a heat treatment and an alitation by a Packing process.
- the first layer should consist of the mixture containing ceramics prevent Al from penetrating into the substrate from the layer and hence the layer due to the depletion of Al their heat resistance is reduced.
- JP 55-082759 A discloses a method for improving the thermal resistance a coating that is based on a substrate made of a Ni or Co-based alloy is applied, wherein during coating a metal or an alloy powder mixed with ceramic elements and then applied to the substrate becomes. A binder and a subsequent heat treatment can be used be performed. The method is used for components of e.g. Gas turbines used, which are exposed to hot gas corrosion.
- the object of the present invention is a method for manufacturing to create an armor of the type described at the outset, which can be manufactured can be carried out as easily as possible and high-quality armor results.
- the solution to this problem is characterized according to the invention by the steps: Prepare a slip by mixing a binder solution with an Al and / or Cr containing starting powder and at least one element Addition powder comprising Al, Pt, Pd or Si, the addition powder being at a starting powder containing Al only does not include Al; Apply the slip on the surface to be armored; Add ceramic hard particles to the slip before or after application of the slip, the size of which is chosen so that they protrude over the layer after heat treatment; Drying the slip layer at a temperature from room temperature to 450 ° C; and heat treatment the slip layer at temperatures from 750 ° to 1250 °.
- the advantage of this method is that the armor with a manufacturing technology simple processes can be applied to the component. Also are the ceramic hard particles securely embedded in the slip layer and with the Component firmly connected.
- the hard particles are Slurry mixed before application to the surface to be armored. To this The particles are uniform in the slurry in suspension distributed.
- the hard particles are deposited in the slip layer is used, e.g. a special arrangement of the particles can be achieved on the surface to be armored.
- Hard particles made of BN, SiC or Al 2 O 3 are preferably used, since they are harder than the slip layer and can cut into inlet linings or the like during operation.
- the starting powder consists of MCrAlY, the starting powder - like the added powder - preferably in a grain size distribution of 5 up to 120 ⁇ m.
- the M stands for at least one of the elements Ni or Co. Instead of Y, Hf or Ce can also be used.
- the slip is applied to the surface of the component to be armored preferably by spraying, brushing or dipping, which means that the process is manufacturing-related can be carried out easily and inexpensively.
- spraying, brushing or dipping which means that the process is manufacturing-related can be carried out easily and inexpensively.
- Layers can be applied locally in a simple manner, even geometrically apply complicated components. In addition, they are not expensive and complex Spraying or evaporation systems required.
- the slip layer is in protective gas, e.g. in argon, or in Vacuum is heat treated, heat treating the layer over 1-4 Hours, preferably over about 2 hours, is performed to the slip layer to connect with the component and the hard particles via diffusion.
- protective gas e.g. in argon, or in Vacuum is heat treated, heat treating the layer over 1-4 Hours, preferably over about 2 hours, is performed to the slip layer to connect with the component and the hard particles via diffusion.
- the metallic component preferably consists of an alloy based on nickel or cobalt, the component being engine-ready, e.g. a turbine blade can, the armor is applied to the tip of the blade.
- the addition powder preferably makes up up to 35% by weight of the total weight of starting and addition powder.
- an MCrAlY powder with an added powder mixed to a suspension with a conventional inorganic binder In the The suspension contains 5-10% by weight of the binder and additionally 5-7% water % By weight.
- the grain sizes of the powder particles are between 5 and 120 ⁇ m.
- BN particles In this flowable and sprayable mass is introduced BN particles, their size lies above that of the powder particles.
- the blade tip of a turbine blade is made into a mass Nickel-based alloy immersed in such a way that on the to be armored Blade tip forms a slip layer.
- the one containing the particles could Slip e.g. also with a brush, forming a layer on the tip of the blade be applied.
- the dried slip layer is then at 1000 ° C for about 2 hours in a vacuum heat treated to bond the slip layer to the material of the Turbine blade and with the hard particles to achieve by diffusion. Sintering the MCrAlY particles present in spherical form at least partially together. In addition, Ni can also escape from the base material and into the slip layer diffuse. After the heat treatment, the ceramic hard particles stand from BN or the like to the outside over the slip layer and can and protect the blade tip during operation.
- the BN particles are firmly connected to the blade tip via the slip layer and can collide with one another when the gas turbine is in operation Cut in the run-in covering to prevent damage to prevent the blade tip and the gap size between the rotating and to keep the standing component as low as possible.
