Definitions

  • the invention relates to a device for the gasodynamic projection of materials in powder form for use in mechanics and other industrial fields to form functional coatings providing different properties on the treated surfaces.
  • the device includes a pressurized gas source, a powder feeder, a carrier gas heater, an antechamber and a supersonic nozzle.
  • the deposition technology is performed as follows.
  • the gas is injected into the powder feeder and the gas heater where it is heated and then injected into the mixing antechamber.
  • the gas arrives in the supersonic nozzle where it is accelerated to a desired speed.
  • the mixture of gas and powder is fed into the mixing antechamber from which it enters the supersonic nozzle where the particles of powder are accelerated.
  • the powder particles strike the treated surface with a desired speed and concentration and thereby form a deposit.
  • the insufficiency of this technical process is that the powder can be fed only in the subcritical part of the supersonic nozzle. Therefore, the control of flow parameters of the two-phase flow in a wide parametric domain is impossible.
  • Another disadvantage is that, during the deposition of composite coatings (several metallic materials or not), it is impossible to separately feed the components (metal or not) into the supersonic nozzle simultaneously.
  • Composite deposits (metal or not) can only be formed from the mechanical mixtures of different powders prepared for this purpose. Optimum spraying conditions for two or more powders with essentially different properties can not be ensured.
  • He is also known by the document RU 2190695 a device for the gasodynamic projection of powder materials which makes it possible to inject the mixture of gas and powder into the subcritical or supercritical parts of the supersonic nozzle, which makes possible the variation of the parameters of the projection method.
  • the disadvantage of this device is that, as in the previous case, composite coatings can only be formed from mechanical mixtures of different powders prepared in advance. Optimum spraying conditions for different powders can not be ensured at the same time.
  • the device makes it possible to supply different powders consecutively via a single point of powder supply. In this case, only the multilayer coatings can be formed and not the composite coatings with a uniform distribution of components.
  • WO 20061123965 which is considered to be the closest state of the art, discloses a device for cold gasodynamic projection of powder materials comprising a main feed means for separately feeding at least two powders in the subsonic part and / or in the antechamber, the device being characterized in that the supersonic nozzle comprises at least one additional means for feeding at least one powder into the supersonic part of the nozzle.
  • the additional means of the WO 2006/123965 are not designed to be mounted coaxially to the supersonic part of the nozzle.
  • the present invention makes it possible to telescopically move the additional powder supply points by varying the length of the turbulent flow mixing zone and, by this, to optimize the projection conditions for the different powders.
  • an object of the present invention is to expand the functional and technological capabilities of a cold gas-dynamic spraying device for powder materials, including for the deposition of composite coatings under optimal conditions for each powder composing the mixture.
  • the device provides a main supply of at least one powder material in a supersonic nozzle, its acceleration by a flow of heated gas and, simultaneously, at least one additional supply of at least one powdered material via at least one an additional feed point at the outlet end of said supersonic nozzle forming a multi-component stream of gas and powder.
  • the invention relates to a projection module comprising an electric pressure gas heater and a supersonic nozzle having an outlet, connected to the heater outlet and, at the powder supply point in the supersonic nozzle, a container of powder supply whose output is connected to the powder supply point in the supersonic nozzle.
  • the supersonic nozzle comprises a main powder supply means for separately feeding at least two powders and receiving at least one additional means for supplying at least one powder in the supersonic portion of the nozzle.
  • each additional supply means comprises an additional nozzle connected to a powder supply container adapted to be mounted coaxially with the supersonic portion of the nozzle.
  • a first additional supply means is engaged on the outlet orifice of the supersonic nozzle leaving a free space between it and the outer wall of the nozzle forming a circular powder supply duct; the following additional supply means being mounted, leaving a free space with respect to the outer walls of the foregoing additional supply means delimiting a circular supplementary powder supply duct between two consecutive additional supply means.
  • each additional supply means comprises an electric heater and a powder supply container.
  • the additional powder supply means can be moved telescopically with respect to each other and with respect to the supersonic nozzle.
  • the circular powder supply ducts of the additional points are made with transverse sections of different shapes, for example, round, oval, rectangular or slit.
  • the circular powder feed conduits of the additional points are made with a constant cross section.
  • the circular feed pipes of the additional points are made with a variable cross section.
  • the device comprises a control module connected to the electric gas heater compressed by an electric cable.
  • each heater is powered electrically.
  • main supply means are connected to subsonic and / or supersonic parts of the nozzle.
  • the gasodynamic projection device of the proposed powder materials makes it possible to create projection conditions that will be optimal simultaneously for two or more powders with substantially different properties.
  • the device for cold gas-flow spraying of powder materials comprises an electric pressure gas heater 1, a supersonic nozzle 2 with an antechamber 3, a carrier gas supply point 4, a main feed point of powder mixture for supplying the powders separately in a subsonic part 5 and / or a supersonic part 6 of the nozzle, this main supply point being connected to the powder feeders 7 and 8 by means of a flexible pneumatic conduit.
  • the supersonic nozzle 2 comprises additional powder supply means having different properties which create additional feed points 9, 10 in the supersonic portion 6 of the nozzle.
  • the additional points (one or more) 9, 10 are in the form of interchangeable elements which may be additional nozzles which are mounted consecutively and coaxially with the supersonic part 6 of the nozzle so that the first additional point is mounted on the nozzle.
  • outlet orifice of the supersonic nozzle leaving a free space between it and the outer wall of the nozzle and thereby forming a circular conduit 11 powder supply
  • the following points are mounted leaving a free space relative to the outer walls of the preceding points and thereby forming a circular conduit 12 of powder supply between the preceding and the following
  • the additional powder supply points can be moved telescopically relative to each other and by compared to the supersonic nozzle.
  • Circular ducts 11, 12 for feeding powder additional dots are made with cross sections of different shapes, for example, round, oval, rectangular or slot.
  • Each additional powder supply means preferably has an electric heater 13, 14 and a powder supply container 15, 16.
  • the additional powder supply points can be made with constant cross sections or not.
  • the carrier gas contained in the electric heater 1 is injected into the antechamber 3 of the supersonic nozzle 2 via the carrier gas injection point 4.
  • the desired pressure and temperature of the carrier gas are given in the antechamber 3.
  • the carrier gas reaches a supersonic speed.
  • the mixture of gas and powder is injected into powder feeders 7 and 8 via the main powder supply point for supplying the powders separately in the subsonic portion 5 and / or the supersonic portion 6 of the nozzle 2.

They pass through the electric heaters 13, 14, reach the desired temperature and, via the circular conduits 11, 12 of powder supply. , arrive in the supersonic part of the nozzle. Then, a mixture of turbulent flows is made and, at the outlet of the nozzle, a multi-component flow of gas and powders occurs and is directed to a substrate 17 to form a composite coating.
