Definitions
- the invention relates in particular to a soldering method in which abrasive particles, in particular cubic boron nitride, are applied in a matrix made of a solder material and are intended to have better adhesion in the matrix material.
- the optimal gap in gas turbines or aircraft engines has a decisive influence on the efficiency and performance of these machines.
- An established system for setting this is a rub-in layer on the housing side (e.g. honeycombs), into which the rotating parts (e.g. turbine blades) rub themselves. This makes it independent of manufacturing tolerances, asymmetrical housing deformation,
- cBN Cubic boron nitride
- cBN does not bond particularly well with other materials.
- the embedding material (matrix) for the turbine area must be resistant to high temperatures. Embeddings in e.g. Resin derivatives such as those used in the manufacture of abrasives (US 2013/004938 Al) are therefore not possible.
- No. 8,308,830 B2 discloses coated particles made of cubic boron nitride which have two layers of coatings.
- US 4,399,167 discloses the metallic coating of abrasive particles.
- No. 10,183,312 B2 discloses coated abrasive particles with a soldering layer, this soldering layer representing the matrix of the layer to be produced.
- the object is achieved by a particle according to claim 1, a method according to claim 2, a layer system according to claim 3 and a sealing system according to claim 4.
- abrasive particles such as cBN grains are provided here as an example of abrasive particles with an additional bond-friendly / reactive coating instead of pure abrasive grains.
- These metallic coatings are in particular nickel (Ni) or titanium (Ti).
- connection and embedding of the cBN grains is significantly improved. This increases the holding force and thus the grinding effect of the cBN, and
- the surface quality is significantly increased.
- a low manufacturing tolerance or a high surface quality is required for the gap design.
- the gaps can thus be designed to be narrower and lead to a higher efficiency of the gas turbine.
- Figure 1 shows a coated abrasive particle
- Figure 2 shows a layer system
- the inside of the particle 1 has a core made of an abrasive particle 4, in particular cubic boron nitride (cBN), with a layered layer 7 made of a metal, preferably titanium (Ti) or nickel (Ni), which results in a better connection in one Solder material leads.
- abrasive particle 4 in particular cubic boron nitride (cBN)
- cBN cubic boron nitride
- a layered layer 7 made of a metal, preferably titanium (Ti) or nickel (Ni), which results in a better connection in one Solder material leads.
- metal are meant metallic materials, including metallic alloys.
- a layer system 10 is shown schematically in FIG.
- the layer system 10 is preferably a turbine component of a sealing system which is intended to have an abrasive coating 22 on one end.
- the component as a layer system 10 has a substrate 13, in particular a metallic and very particularly a nickel or cobalt-based superalloy.
- a material with abrasive particles in particular cubic boron nitride (cBN)
- a solder material 19 which has the particles 1 according to FIG. 1 is used in the form of a plasma spraying process, HVOF or a soldering paste or in the form of tapes.
- the applied solder material 19 is then the outer
- the solder material 19 has in particular a melting point which is at least 10K, in particular at least 20K lower than the material of the substrate 13.
- Typical elements such as boron (B), silicon (Si), phosphorus (P), hafnium (Hf), zirconium (Zr) or manganese (Mn) and / or germanium (Ge) are preferably used as melting point depressants in the solder.
- the particles 1 are both completely present in the layer 22 and also protrude from the surface 25 of the layer 22.
- the layer 22 thus has three different materials, that of the abrasive particle 4, that of the layer 7 around the particle 4 and the solder material 19.
- the layer 16 is then preferably applied only to the blade tip of a turbine blade.
- the turbine rotor blade can and generally will also have metallic and / or ceramic coatings on the blade and / or the blade platform, but these do not have the particles 1.
- the stator or the housing of a turbine also has a protective coating into which this abrasive layer 16 rubs.
- the coating on the housing or stator can only be metallic, only ceramic, or have a layer system of metallic adhesion promoter layer and outer ceramic layer or multilayer ceramic layers.
- the layers or the layer system of the housing are designed in such a way that they are mechanically softer than the abrasive layer 16, so that grinding is possible. This can be achieved by the composition of the metallic or ceramic coating and / or also by adjusting the porosities of the layer or layers, such as longitudinal grooves preferably made by means of a laser or water jet.
