Definitions

  • the present invention relates to a method for producing a component and/or a coating comprised of a vibration-damping alloy or intermetallic compound.
  • the invention also relates to a component produced using such a method.
  • Shape-memory alloys are suitable for use in vibration damping, provided their structure is correspondingly designed.
  • Shape-memory alloys have long been known in the art.
  • German patent document DE 40 06 076 C1 describes a NiTi shape-memory alloy which, with a nearly stoichiometric composition, is characterized by an especially high degree of reversible deformation in one-way and two-way effects, high tensile strength and ductility, and a very high resistance to corrosion.
  • this shape-memory alloy exhibits an outstanding degree of shape-memory effect stability with respect to thermal cycles.
  • this alloy can be heated relatively far beyond the A 1 temperature (temperature of the completion of austenite formation) without developing damaging irreversible structural changes which reduce the degree of shape-memory effect or undesirably shift the conversion temperature.
  • an iron-nickel-cobalt-titanium shape-memory alloy and a method for producing the alloy are known from German document DE 41 20 346 A1.
  • the shape-memory alloy is produced via a casting method, after which it is deformed at temperatures of between 1,050° C. and 1,052° C., and then quenched; it is then subjected to a solution treatment over a period of 10 to 30 hours at temperatures of between 1,150° C. and 1,250° C. in an inert gas atmosphere, after which it is again quenched.
  • the shape-memory alloy is exposed to temperatures of between 500° C. and 650° C. for a period of between 10 minutes and 150 hours, after which it is quenched for a third time and then subjected to training deformation involving one to fifty repetitions.
  • a method for producing Cu/Zn/Al-type shape-memory alloys via a powder-metallurgical process is known from WO 81/02587.
  • the finished powder is encapsulated, cold-compressed, heat-compressed, and extruded.
  • this method does not fulfill all necessary requirements, and the formed components often are inadequate in terms of their mechanical properties.
  • Another method known from this publication involves again producing the shape-memory alloy, via a powder-metallurgical process, as a fine-grained memory alloy of the Cu/Zn/Al type with a ⁇ -high temperature phase, and with dispersoids in the form of Y 2 O 3 and/or TiO 2 particles embedded in the matrix that serve to inhibit grain growth.
  • the production process is accomplished with the help of mechanical alloying.
  • One object of this invention is to further develop a method for producing a component and/or a coating from a vibration-damping alloy or intermetallic compound such that the properties are improved, the range of application is expanded, and the production process is simplified.
  • This object is attained with respect to the method by producing the at least one of the compound and the coating via thermal spraying.
  • a component and/or a coating are/is produced via a thermal spraying process.
  • the metallic coating material is deposited on the surface of a carrier material or component in the form of heated and accelerated spray particles.
  • Precise temperature control combined with a high particle speed results in formation of vibration-damping properties.
  • a solid object is coated with a heated and accelerated metallic material, which e.g. is fed into a thermal spray gun in the form of powder or wire.
  • the surfaces of the solid object are not fused during the spray process.
  • interdiffusion takes place between the component and the applied layer.
  • adhesion is preferably the result of physical interaction.
  • a metallurgical linkage then occurs in conjunction with the coating process via diffusion annealing at temperatures >800° C. Precise temperature control during the coating process is essential for formation of a well-defined structure.
  • This spraying process may also be used to spray materials that are not miscible with the base metal and/or that form brittle, intermetallic compounds.
  • plasma spraying within a vacuum is used as the spraying process.
  • gas plasma is used as the heat source for heating and accelerating the material to be used.
  • Spraying within a vacuum prevents the formation of oxide streaks as a result of the oxidation of the sprayed material during the coating process, and positively affects the structural formation.
  • an RSPD rapid solidification processing deposition, in which alloys are deposited on a carrier via atomization from the molten bath, with extremely rapid hardening
  • RSPD rapid solidification processing deposition, in which alloys are deposited on a carrier via atomization from the molten bath, with extremely rapid hardening
  • a high-speed powder or plasma spray process may be used as the spraying process.
  • combustion of a fuel gas-oxygen mixture takes place in a combustion chamber.
  • the pressure that builds up within the chamber results in high particle speeds in a connected expansion nozzle. Both methods result in improved adhesion and coating density.
  • a cold-kinetic compaction process can be used as the spraying method.
  • German publication DE 197 41 019 In order to ensure a high resistance to corrosion, a nickel-titanium alloy—as described in German publication DE 197 41 019—is used. This alloy is formed into a component in accordance with the method described above, or is applied to a component as a coating. The disclosure of German publication DE 197 41 019 also applies in connection with this application.
  • the temperature during the spraying process preferably is between 1000° C. and 1,000° C.
  • the vibration-damping alloy is applied to a component as a coating.
  • the advantage of this is that the material can be applied via the method indicated in the form of a coating of any desired thickness.
  • components and semi-finished products can be produced, and components and machinery elements can also be coated in a simple manner.
  • the vibration damping achieved via the application of a coating can be established locally at specific points on a component. In this way, high stability and rigidity of the component can be combined with good damping properties.
  • components, especially engine components and machine tool components, which are supplied with a vibration-damping coating in accordance with the invention exhibit significantly improved vibration behavior, and thus improved operating results.
  • coatings of any thickness and any geometry can be produced.
  • the vibration-damping alloy is applied to the component as a coating measuring 0.1 to 25 mm in thickness.
  • the surface of the component to be coated is prepared prior to coating, for example via an abrading process, such as an irradiation process, e.g. laser or arc exposure, or plasma etching.
  • an abrading process such as an irradiation process, e.g. laser or arc exposure, or plasma etching.
  • a diffusion-heat process is conducted in order to increase the adhesion of the coating to the component.
  • the layer applied to the component possesses vibration-damping properties.
  • a metallographic evaluation shows a dense coating with a very secure connection to the carrier material that is metallurgically free from defects, with a porosity of ⁇ 1%.
  • both semi-finished products and components can be produced from, and thus coated with, a vibration-damping alloy, e.g., a shape-memory alloy, or a vibration-damping intermetallic compound.
  • a vibration-damping alloy e.g., a shape-memory alloy, or a vibration-damping intermetallic compound.
  • a further application of the process specified in the invention involves components from the field of engines, such as housings, disks, and blades that are vibration-damped with a coating and thus are placed under reduced stress, resulting in a longer lifespan.
  • any case in which the coatings are applied to machinery elements for the purpose of vibration damping, in accordance with the above-described process, is advantageous when a high degree of bond strength and high thermal and corrosion resistance are required.
  • FIG. 1 is a perspective view of a fixed blade segment of a gas turbine
  • FIG. 2 shows a tool-receiving socket with a tool.
  • FIG. 1 shows a fixed blade segment 1 of a gas turbine that has been coated in accordance with the invention.
  • the four fixed blades of the segment 1 that are bombarded by the operating gas are provided at least over a majority of their surfaces with a vibration-damping coating 2 comprised of a suitable alloy or intermetallic compound.
  • FIG. 2 shows a component in the form of a tool-receiving socket 3 for a milling cutter 4 or some comparable tool, wherein the tool-receiving socket 3 as a whole is made of a vibration-damping alloy or a vibration-damping, intermetallic compound.
