Definitions

  • the invention relates to a method for producing a coating on a Workpiece or a molded part in a cold gas injection process, using a carrier gas and powdery spray particles are relaxed in a cold gas spray gun and the spray particles at high speeds, for example up to 2000 m / s, to be brought.
  • the spray particles are added as powder by conveying the particles into the main gas stream with an auxiliary gas stream.
  • the powder usually comprises particles with a size of 1 to 50 ⁇ m.
  • the spray particles receive the high kinetic energy during gas expansion.
  • the gas is expanded in a nozzle after the injection of the spray particles into the main gas jet, the carrier gas and spray particles being accelerated to speeds above the speed of sound.
  • Nitrogen, helium and nitrogen-helium mixtures are generally used as carrier gases. The same gas or different gases can be used for the main and auxiliary gas flow. Nitrogen, the most commonly used carrier gas, is a good inert and inexpensive gas for the cold gas spraying process. Air, on the other hand, is only considered for a few applications despite its high nitrogen content due to the oxygen content. With helium as the carrier gas, as fundamental studies show, the highest particle speeds are achieved. Since very large amounts of carrier gas are required, in practice only nitrogen-helium mixtures with a low helium content are used.
  • the consumption of carrier gas for cold gas spraying is between 40 and 150 m 3 / h.
  • the gas consumption depends on the carrier gas used for the main and auxiliary gas flow and the material of the spray particles.
  • helium as the carrier gas have shown that in order to spray 3 kg of spray material (eg McrAIY), a bundle of helium with 110 m 3 is necessary.
  • the focus is on economic aspects that do not allow the use of carrier gases that are optimal in terms of process technology.
  • the present invention is therefore based on the object of a method specify which one is the best one for the cold gas spraying process Carrier gas for main and auxiliary gas flow allowed and the process of Cold gas spraying improved.
  • the object is achieved in that the cold gas spraying process in Low pressure is carried out at values below 800 mbar (80 kPa).
  • This can the spray gun be mounted in the housing of a vacuum chamber so that it Aiming into the interior or the cold gas spray gun and that too coating workpiece or the molded part in a vacuum chamber brought.
  • the cold gas spray gun and the spray material are in one Vacuum chamber, the entire spraying process takes place under Vacuum conditions instead.
  • the Spray particle speed which is achieved with the method according to the invention, is significantly above the spray particle speed, which with an analog arrangement is achieved under normal conditions.
  • the cold gas spray process under vacuum conditions also allows Use a wide spray jet. Maintaining the high The speeds of the particles in low pressure right down to the workpiece can be seen Particularly pronounced when the workpiece and spray gun are more than 60 mm. This is because the speed of the Particle increases immediately after leaving the spray gun before the Braking caused by the ambient air. Are the spraying distances The advantages of low pressure and the associated benefits are shown over 60 mm Absence of deceleration clearly. Spray distances of more than 60 mm have been found as advantageous if large workpieces or a large number of workpieces are coated the spray jet continues on the longer way to the workpiece fanned out and the fanned out beam compared to the bundled beam Coating over a larger area is made possible. Furthermore, if the spray distance so large, even workpieces with an uneven surface, where the distance varies widely between spray gun and material surface, without problems be coated.
  • the cold gas spraying process is carried out a pressure between 1 and 500 mbar (0.1 to 50 kPa), preferably between 20 to 100 mbar (2 to 10 kPa). At this low pressure, the above are Advantages of cold gas spraying under vacuum conditions are given. This print area is easily achieved with commercially available vacuum pumps.
  • the invention has the great advantage that now with much less effort same high particle speeds can be achieved or with the same effort higher speeds. If you need e.g. 40 bar to under ambient pressure Bringing particles to a desired speed is sufficient at 500 mbar Pressure in the chamber 20 bar gas pressure. When spraying in a chamber at 100 bar even 4 bar gas pressure are sufficient for the same effects
  • the method according to the invention is in principle with all gases and gas mixtures as well as air feasible.
  • the noble gases and inert gases are particularly suitable as gases Gases and their mixtures.
  • helium, argon and nitrogen as well as mixtures of these gases.
  • Helium is particularly advantageous in Carrier gas included. With helium and helium-containing mixtures as carrier gas very high particle speeds achieved. High spray particle speeds guarantee dense and firmly adhering coatings and thus high quality Cold gas spraying results.
  • the carrier gas contains at least 20% by volume of helium with particular advantage preferably between 30 and 80 vol .-%. These helium components ensure the high spray particle speeds. Have been particularly advantageous Mixtures of helium and nitrogen as well as of helium and argon have been proven. But argon-nitrogen mixtures are also used.
  • spray particles with a grain size of up to 150 ⁇ m. Larger spray particles must be accelerated to higher particle speeds than smaller particles until their kinetic energy is sufficient to adhere to the workpiece to be coated.
  • Spray particles that have been customary to date have particle sizes in the range from 5 to 25 ⁇ m, in some cases also up to 50 ⁇ m, and are usually accelerated in air or nitrogen.
  • helium or helium-containing gas mixtures as carrier gas on a larger scale. Helium achieves significantly higher spray particle speeds, which means that even larger spray particles with a grain size in the range of 80 to 150 ⁇ m are accelerated sufficiently so that they adhere well to the workpiece.
  • the carrier gas is fed to a recovery unit after the cold gas spraying process.
  • the recovery unit cleans the carrier gas of impurities that got into the carrier gas during cold gas spraying and during supply and discharge.
  • the used carrier gas is removed from the vacuum chamber with a vacuum pump, which is preceded by a particle filter, and fed to the recovery unit.
  • the recovery unit cleans the used carrier gas from the impurities and possibly separates individual gas components.
  • the recovery of helium is economically very advantageous and also enables helium to be used as the carrier gas.
  • the cleaned carrier gas or the recovered gas component is then either collected in a container and used for a different purpose or, after being stored in an intermediate container, is fed back to the cold gas spraying device.
  • the object is achieved with respect to the device in that the cold gas spray gun (3) and the workpiece / molding (5) to be coated in one Vacuum chamber (4) are arranged. This arrangement enables cold gas spraying under vacuum conditions with all its advantages mentioned above.
  • FIG. 1 shows an inventive device for cold gas spraying under Vacuum conditions.
  • the gas feed line 1 reaches the main gas stream, for example a helium-nitrogen mixture with 40 vol .-% helium, and via the line 2, the spray particles in Auxiliary gas flow into the vacuum chamber 4, where there is a pressure of 40 mbar, and there in the cold gas spray gun 3.
  • the supply lines 1 and 2 are in the Inserted vacuum chamber 4, in which both the cold gas spray gun 3 and the workpiece 5 is also located. The entire cold gas spraying process takes place in the Vacuum chamber 4 instead.
  • the carrier gas which during cold gas spraying together with the spray particles from the spray gun 3 and the spray particles to the workpiece carries, after the injection process in the vacuum chamber 4.
  • the used Carrier gas is removed via the gas line 6 from the vacuum chamber 4 by means of the Vacuum pump 8 removed. Between the vacuum pump 8 and vacuum chamber 4 is the Particle filter 7 switched, which free spray particles from the used carrier gas removed so that the solid particles do not damage the pump.
