Definitions
- the present invention relates to the general field of powdery materials for the formation of seals abradable. It finds its application in particular in the field of turbomachinery.
- abradable seals Materials with an abradability property are commonly used in many applications, including the formation of seals.
- the abradable seals are in particular used at the rotary parts of a turbomachine, such as compressors, to reduce air or gas leaks could affect the performance of the turbomachine.
- a turbomachine compressor consists of a plurality vanes fixed on a shaft which is mounted in a fixed ring. In operating, the shaft and the vanes rotate inside the ring compressor.
- the internal surface of the ring of compressor is usually covered with a material coating abradable and the compressor shaft is mounted in the ring compressor so that the top of the blades is closest possible abradable coating.
- abradable coating is therefore to form a seal between the fixed parts and the moving parts of the compressors of a turbomachine.
- the seal made of abradable material provides reduced clearance without damaging the parts of the rotor coming into contact.
- Interference between the fixed parts and mobile compressors are mainly due to expansions differential of fixed and moving parts during transient compressor operation. Creep phenomena of the blades, unbalance and vibration can also cause such interference.
- silicon-based materials have satisfactory abradability and erosion characteristics but their use at high temperatures is limited.
- the pulverulent material described in US patent 5,434,210 This material is limited to an operating temperature of approximately 400 ° C. Above of this temperature, the metallic matrix of this material shrinks and densifies which can cause wear on the top of the vanes opposite.
- materials based on chromium and nickel are relatively stable and resistant to high temperature but have too low abradability and erosion characteristics, in particular when placed next to alloy compressor blades uncoated titanium.
- a NiCrAl alloy although having a good temperature behavior, is relatively hard and thus causes excessive wear on the blades.
- the present invention therefore relates to a pulverulent material intended for the formation of an abradable coating for seals that meet the criteria listed above.
- Another object of the invention is to form a coating abradable which exhibits satisfactory behavior for applications to temperatures up to 550 ° C.
- Yet another object of the invention is to provide a joint abradable seal usable in front of blades or wipers titanium alloy without the need for a protective coating at the top of these.
- a powder material for the formation of an abradable coating, characterized in that it comprises a metallic powder mainly based on aluminum and containing manganese or calcium.
- thermo properties of this new pulverulent material are superior to those of the materials currently used for the formation of abradable seals.
- the applicant has in fact noticed that the temperature of the eutectic bearing of an AlMn or AlCa alloy is sufficiently high compared to that of an AlSi alloy for example, so that it can reach temperatures of around 550 ° C without transformation or degradation of the material.
- an organic powder is added in order increase the porosity of the coating obtained, promote abradability during contact between fixed and mobile parts and allow the elevation coating temperature.
- a solid ceramic lubricating powder advantageously provides inter-lamellar decohesion sufficient not to generate overheating at the blades during of contacts between fixed and mobile parts.
- the powdery material obtained thus meets the criteria mentioned above. It is perfectly suited the formation of an abradable coating, especially for seals for sealing the compressors of a turbomachine.
- the ceramic powder comprises one of the following components: boron nitride, molybdenum disulfide, graphite, talc, bentonite, and mica
- the organic powder includes one of following components: polyester, polymethylmethacrylate, and polyimide.
- the metal powder represents between 65% and 95%, the ceramic powder between 3% and 20% and the organic powder between 5% and 20% of the total weight of the material.
- the metal powder may further comprise one or several of the following additional elements: chromium, molybdenum, nickel, silicon and iron.
- Manganese or calcium forming the metal powder advantageously represents between 5% and 20% and the element (s) additional represent at most 10% of the weight of the metal powder.
- the powder metallic is an AlMn5 alloy
- the ceramic powder is nitride of hexagonal boron
- the organic powder is polyester.
- the pulverulent material according to the invention is intended to form a abradable material such as a coating for gaskets of compressors or turbine rings for example.
- the powder material consists essentially of a metallic powder in an alloy mainly based on aluminum.
- the second main metallic element of this alloy can be manganese or calcium, up to 5% to 20% by weight of the metallic powder.
- the metal powder (of the AlMn or AlCa type) can also include one or more of the additional metallic elements following: chromium, molybdenum, nickel, silicon and iron.
- the amount of each of these additional elements does not exceed 5% of the weight of the metal powder, and the cumulative amount of these elements no more than 10% of the same weight.
- the pulverulent material further comprises a organic powder comprising one or more of the following components: polyester, polymethylmethacrylate, and polyimide. It can also be composed of any other polymer type material, for example polyethylene, polyvinyl acetate or polyaramide.
- a ceramic powder can advantageously be added. It includes one or more of the components chosen from the following group of solid ceramic lubricants: boron nitride, molybdenum disulfide, graphite, talc, bentonite, and mica. She can also be composed of other laminated materials based on silicates such as kaolin and other clays.
- the metallic, lubricating and organic powders thus prepared are preferably mixed in the following proportions: the powder metal represents between 65% and 90% of the total weight of the material, the ceramic powder varies between 5% and 20% and the organic powder between 5% and 15%.
- the mixing of the powders can be carried out mechanically. This process consists in mechanically mixing the different components and, thanks to the compression and shear forces generated by the mixer, to obtain agglomerates constituted by each of the initial components.
- the mixture can also be obtained by a other process such as agglomeration-drying or fusion-grinding.
- the pulverulent material is composed of a metal powder made of aluminum alloy and manganese (AlMn5), a ceramic powder made of hexagonal boron nitride (hBN) and an organic polyester powder (PE).
- AlMn5 represents approximately 75% of the total weight of the material
- nitride of hexagonal boron represents about 15% of the total weight
- the polyester represents about 10% of the total weight of the material.
- the pulverulent material thus obtained is intended to be pulverized thermally using known techniques (plasma or flame for example) to form an abradable coating.
- a pulverulent mixture intended for thermal spraying was prepared by mechanically mixing 75% by weight of an AlMn5 powder with 10% by weight of PE and 15% by weight of hBN. A nickel-based substrate was coated with a NiAl5 sublayer. The powder thus obtained was then sprayed by plasma on this substrate.
- the spraying parameters used during this test are grouped in the following table: Plasma gas Argon Hydrogen Flow rates (L / min) 50-70 2,5-5 Pressure (kPa) 100-150 120-170 Intensity (A) 500 Voltage (V) 31 Projection distance 130 mm
- the parameters of the injector used are as follows: Nozzle diameter 6 mm Injector size 2 mm Injector angle 90 degree Movement speed 1600 mm / s Scan interval 5.5mm
- the coating obtained after this spraying forms a abradable coating which has a thickness of approximately 3 mm.
- the coating hardness was measured using the indentation scale R15Y from Rockwell which indicates the hardness of a coating. In the case present, the coating tested has an R15Y indentation value of around 70.
- the substrate sample thus coated then underwent a step sublimation at 500 ° C for four hours. At the end of this sublimation, the coating has an R15Y indentation value of around 60.
- the coating was evaluated on an abradability bench against uncoated titanium alloy vanes.
- the usability of this seal was measured under the following test conditions: Test temperature Ambient temperature Number of blades 3 Blade thickness 0.8mm Speed of blade tips 200 m / s Incursion speed 0.15 mm / s Penetration 0.5mm
- the abradable seal as well obtained has good properties of resistance to erosion compared to at the classic joint in Table II. It is capable of wear by contact with blades of metal alloys, in particular of non-titanium alloys coated, without causing wear of the latter. Stability metallurgical of this seal still allows it to withstand high temperatures of the order of 550 ° C, unlike the seal classic of table II which cannot withstand temperatures too high.

Abstract
Description
- le sommet des aubes ne doit pas subir d'usure trop importante. En effet, bien qu'une faible usure soit tolérée, il est préférable, lors d'un contact, que ce soit le joint d'étanchéité qui soit endommagé ;
- les contacts entre le sommet des aubes et les joints ne doivent pas engendrer d'échauffement des aubes, notamment dans le cas d'aubes en alliage de titane pour lesquelles de tels échauffements peuvent conduire à un début de feu ;
- les joints d'étanchéité doivent résister à l'érosion provoquée par le flux gazeux circulant dans la veine du compresseur ;
- les joints d'étanchéité doivent également conserver les propriétés d'abradabilité dans un environnement oxydant et corrosif. En effet, l'élévation de la température dans les compresseurs provoque une oxydation et les gaz de combustion de la turbomachine ainsi que l'air extérieur engendrent une corrosion de l'environnement ;
- en cas d'usure des joints d'étanchéité, les résidus ne doivent pas provoquer l'obstruction des orifices destinés au refroidissement des compresseurs ;
- enfin, le matériau abradable formant les joints d'étanchéité doit résister aux fortes températures sans présenter de modifications telles que le durcissement, la fragilisation et la décohésion qui pourraient dégrader ses capacités d'abradabilité. Le matériau abradable doit en effet être capable de supporter les différents cycles de fonctionnement de la turbomachine sans se dégrader.
