Definitions

  • the invention relates to a method for the thermal coating of cylinder walls of internal combustion engines according to the preamble of claim 1 and one Device for performing the method according to the preamble of the claim 6.
  • the object of the invention is to provide an easy-to-use method for the thermal coating of cylinder walls of engine blocks of internal combustion engines to propose, on the one hand, the quality of the applied Layer is improved and on the other hand the engine block from contamination is protected.
  • the proposed measure the layer quality is improved in two ways and that at the same time the Engine block can be protected from contamination.
  • the coating particles By blowing the air during the thermal coating at a speed between 7 and 12 m / s through the Cylinder bore is passed, the coating particles not applied reliably removed and the content of oxygen bound in the layer (Oxide content) is kept in an area where both the tribological properties the layer as well as its machinability can be optimized.
  • the air flow cooling the engine block caused by the air flow cooling the engine block.
  • the proposed measure also reduces the pollution of the plasma cartridge.
  • two plasma spraying devices 1, 2, are shown in a schematic representation Engine block 6 and a suction device 18 can be seen.
  • the suction device 18 has four suction nozzles 12, a control device 20 provided with air flaps and a suction pump 25 on.
  • the control device 20 is not the actual one from this illustration Air flaps but only their adjustment mechanism 22 can be seen.
  • control device 20 has one provided with four air flaps Air valve battery 21 on.
  • the four suction nozzles 12 are received in a holder 13 and connected to the control device 20 via flexible hoses 14, wherein the hoses 14 are only hinted at.
  • the hoses 14 lead to a connecting element 15, which is connected to the control device 20 via lines 17 connected is.
  • Lines 23 lead from the control device 20 to the suction pump 25.
  • the control device 20 is also provided with pressure sensors (not shown). provided, by means of which the prevailing during suction in the suction lines 14, 17 Air pressure can be measured.
  • the cylinder liners 8 are coated as follows: First the four suction ports 12 from below through the crankcase 10 of the engine block 6 brought up to the lower end 9 of the cylinder bores 7. Then the actual coating process started by the plasma sprayers 1, 2 in the Cylinder bores 7 introduced and the walls 8 are coated. While of the coating, air is continuously extracted by means of the suction device 18. In this case, the pressure sensors prevailing in the suction lines 14, 17 Air pressure measured. Due to the measured air pressure, the Flow velocity of the air flowing through the cylinder bores 7 is closed the electronic means for calculating the air speed are not shown in detail.
  • the Air flaps and thus the suction cross section can be changed so that the air speed within the cylinder bores 7 in the desired range between 7 and can be kept 12 m / s.
  • the other two cylinder bores 7 are also coated and the flow velocity of those flowing through these cylinder bores 7 Air measured in the manner described above and within the specified Value held.
  • suction device is suitable for the coating of four-cylinder in-line engines and eight-cylinder V-shaped engines. It goes without saying that suction devices for other variants of engine blocks can be provided.
