Definitions

  • the invention relates to a cold gas spraying plant and a cold gas spraying process.
  • the US 6,124,563 and the US Pat. No. 6,630,207 describe pulsed thermal spray processes.
  • the DE 103 19 481 A1 and the WO 2003/041868 A2 describe special spray nozzle designs for the cold gas spraying process.
  • the object is achieved by a cold gas spraying system according to claim 1 and a cold gas spraying method according to claim 29.
  • the powder for a coating 13 is passed through a nozzle 8 onto a substrate 10, for example a component (turbine blade 120, 130, (FIG. 9, 10), combustion chamber wall 155 (FIG. 11) or a housing part (FIG. 9) of a turbine 9), so that a coating 13 forms there
  • the powder comes from a powder container 16, wherein the pressure required for the cold gas spraying is generated by a high pressure gas generator 22, so that a cold gas particle stream 7 is generated by the powder
  • High-pressure gas is supplied as carrier gas in the nozzle 8.
  • the high-pressure gas can optionally be heated by means of a heater 19.
  • the heater 19 can be integrated in the high-pressure gas generator.
  • Cold spraying means that temperatures up to a maximum of 80 ° C - 550 ° C, especially 400 ° C to 550 ° C are used.
  • the substrate temperature is 80 ° C to 100 ° C.
  • the speeds are at 300m / s to 2000m / s.

  • This influencing of the properties of the cold gas particle stream 7 can take place periodically or aperiodically during a coating process.
  • periodic changes in coating times may be followed by aperiodic changes or vice versa.
  • Preferably, only a periodic change of the one or more properties takes place.
  • the influencing means may be, for example, a pulse heating means 25 which alternately, preferably pulsatingly, heats the high-pressure gas of the high-pressure gas generator and thus leads to a modulation of the cold gas particle stream 7.
  • the pulse heating means 25 may also be part of the heater 19.
  • a valve 32 as an influencing means in particular a perforated disc (chopper) 32 may be mounted in front of the nozzle inlet opening 8 '. Since this interrupts the cold gas particle stream 7 periodically or aperiodically, a pulsating cold gas particle stream 7 is generated in the direction of the substrate 10, which causes locally different particle densities p in the beam direction.
  • the valve 32 When the valve 32 is closed, the material accumulates in front of the nozzle 8 and it builds up a higher pressure, which relaxes after opening the valve again.
  • a modulated cold gas particle stream 7 can also be produced by adding the powder from the powder container 16 in changeable amounts per unit time, preferably pulsatingly, to the high-pressure gas. This can be done for example by particular piezoelectric injectors 35 as influencing means.
