Definitions

  • the present invention relates to a method and device for gasodynamic acceleration of powdered materials for use in mechanics and other industrial fields to form functional coatings providing different properties on the treated surfaces.
  • the present invention can be implemented in processes using high velocity impacts between powder particles and a substrate surface such as sanding of surfaces, breaking up / granulating of powder particles, etc.
  • the document UK No. 2257423 thus describes a system which comprises a projection module composed of an electric compressed gas heater and a supersonic nozzle connected to the outlet orifice of said heater and comprising a powder injection module in said nozzle, a module of control connected to the electric gas heater compressed by a flexible pipe and by an electric cable, a powder supply container whose outlet is connected to the powder injection module in the nozzle.
  • said heater comprises a leather cover which envelops a metal frame leaving a free space between it and said frame, the free space being filled with a heat-insulating material and said frame having a heat exchanger and having vents for the circulation of a cooling gas inside the cover.
  • the powder injection module in the nozzle provides, according to a preferred embodiment, the injection of the powder into the supercritical zone of the supersonic nozzle at oblique with respect to the longitudinal axis of the nozzle in order to to increase the efficiency of the projection process by a more uniform distribution of the powder material in the cross-section of the nozzle.
  • the device provides for the use of nozzles having the round or rectangular cross section depending on the geometric shapes of the treated surfaces of a workpiece. Depending on the composition of the material used, the ratio between the length of the supersonic portion of the nozzle and the dimension of the minimum cross section of said nozzle may vary from 20 to 100.
  • the disadvantage of this device is that the dimensions of the supersonic nozzle as an integral part are in no way related to the size of diameter and the density of the material of the projected particles. Therefore, by using this device, it is impossible to communicate to the particles during their movement in the supersonic part of the nozzle the optimum acceleration to reach the impact velocity on the surface of the maximum treated part susceptible of to be achieved by the projected particles in view of their size and density characteristics and, consequently, to ensure the maximum quality of the resulting coatings.
  • the document UK No. 2288970 discloses a cold gasodynamic projection system of powder materials which comprises an electric compressed gas heater, a supersonic nozzle (called Laval) connected by an outlet orifice to said heater and having a groove located between the convergent and divergent portions of said nozzle, a powder injection module in the nozzle having injection points for injection of powder into the nozzle and located upstream of the nozzle after the groove, said injection module comprising at least one container of powder supply connected by pipes to said injection points of at least one powder material, and the geometric characteristics of the nozzle portion located upstream of the powder injection points and for accelerating the powder particles injected into the nozzle corresponding to the following conditions: 0.015 ⁇ B ( Jump / Sinj -1) / L ⁇ 0.03, where Sout is the cross sectional area of the nozzle to at its outlet end, Sinj is the cross-sectional area of the nozzle at the position of the powder injection points, L is the length of the portion of the nozzle intended to accelerate the injected powder particles in the nozzle
  • the disadvantage of this device is that the dimensions of the supersonic nozzle as an integral part are in no way related to the size of the diameter and the density of the material of the projected particles. Therefore, by using this device, it is impossible to communicate to the particles during their movement in the supersonic part of the nozzle the optimum acceleration to reach the impact velocity on the surface of the maximum treated part susceptible of to be reached by the projected particles taking into account their size and density characteristics and, consequently, to ensure the maximum quality of the resulting coatings.
  • the formula 0.015 ⁇ B (Jump / Sinj -1) / L ⁇ 0.03 used by this method and this device does not determine the ratio of the length of the nozzle portion for accelerating the powder particles to the minimum dimension of the cross-section at the position of the powder injection points.
  • the document US 6,743,468 The closest known state of the art describes a method and device for depositing coatings on the surface of a workpiece by kinetic projection and thermal spraying using one and the same nozzle.
  • the device according to this invention comprises a gas heater allowing the user to switch from the kinetic projection mode which is carried out without thermal softening of the particles to thermal projection mode with thermal softening of particles before the projection.
  • Such a nozzle construction broadens the spectrum of applications of the method in kinetic projection.
  • this device is unable to provide a high impact speed on the surface of a workpiece treated with particles having a size of less than 1 ⁇ m in diameter because particles of such dimensions would be slowed considerably in a compressible boundary layer formed by a supersonic jet impacting a target.
  • the object of the present invention is to impart to the particles during their movement in the supersonic part of the nozzle the optimum acceleration to reach the impact velocity on the surface of the maximum treated part susceptible to to achieve the given gas parameters (composition, temperature and stagnation pressure) by means of the development and application of the nozzles having the optimal geometrical parameters, in particular the ratio between the length of the supersonic part and the critical section, specifically calculated for the use of particles having a size and density of the material constituting them.
  • the outlet orifice of the nozzle used must have dimensions specially provided for this purpose.
  • the supersonic part of such a nozzle must be shortened.
  • the particles to be sprayed must be selected having a size that would allow them to reach the maximum impact velocity at the target surface likely to be reached.
  • the particles of small dimensions are well accelerated in the nozzle, but strongly slowed in the compressible boundary layer.
  • the present invention advantageously solves the problems mentioned above by proposing a cold gas-dynamic acceleration method of at least one powder material comprising feeding said powder material into a supersonic nozzle via an injection point, its acceleration by a supersonic gas flow and its deposition by impact on the surface of a workpiece, the method taking into account the size of the particles and the density of the material constituting them as well as the parameters of the gas in order to give the particles of powder entrained by the gas flow the maximum speed that can be reached at their impact on the surface of the treated part by accelerating the flow of gas and powder in the supersonic part of the nozzle whose length and transverse dimension correspond to the following conditions:
  • the method according to the invention can use as compressed carrier gas: compressed air, compressed nitrogen, compressed helium or a mixture of these gases.
  • the compressed gas is heated to temperatures between 300 and 9800 K.
  • the powder materials used are, for example, made up of particles having a size of between 0.1 and 1000 ⁇ m.
  • the method may use: metallic powder materials, nonmetallic powder materials, metal powder mixtures having values of ⁇ p d p near, non-metallic powder mixtures having values of ⁇ p d p near or mixtures of metallic and non-metallic powders having values of ⁇ p d p near.
  • the present method is implemented by a cold gas-dynamic acceleration device of at least one powder material comprising a supersonic nozzle connected to a powder injector, a powder feeder connected by an outlet orifice to said powder injector.
  • One of the advantages of the method and apparatus for the gas-powder spraying of proposed powder materials is that depending on the particle size and the density of the material constituting them selected for a separate technological operation as well as the pressure and gas temperature (for example, air, nitrogen, helium or the mixture of at least two of these gases), the dimensions of the supersonic part of the nozzle used may be calculated so as to ensure the maximum speed of the impact of the particles on the target surface that can be reached, and thereby to advantageously improve the quality of the deposit, the efficiency and the quality of the surface cleaning process, the efficiency of the fragmentation / granulation of particles.

  • the process is carried out as follows.
  • the simulated ratios presented above are used to calculate the main dimensions of the nozzle: the length of the supersonic part and the critical section (the height for a flat nozzle and the diameter of the critical section for an axisymmetric nozzle). Particles entrained by a flow of gas in such a specially calculated nozzle are given the maximum speed that can be achieved at their impact on the surface of the treated part by accelerating the flow of gas and powder in the part. supersonic of said nozzle, flat or axisymmetric.
