Definitions

  • the invention relates to a method for applying or introducing a material onto or into a surface with a surface processing device, wherein a material mist is extracted with a predetermined suction power and the surface and the surface processing device are moved relative to one another, according to the preamble of claim 1.
  • the invention further relates to a device for applying or introducing a material onto or into a surface with a surface processing device, wherein a suction device is provided for extracting material mist with a predetermined suction power and a relative movement takes place between the surface processing device and the surface, according to the preamble of Claim 6.
  • hypoeutectic aluminum-silicon alloys mainly used for cylinder crankcases are unsuitable for the tribological loading of the piston-piston ring-cylinder raceway system due to the low proportion of the wear-resistant silicon phase.
  • Hypereutectic alloys, such as the alloy AISil 7 Cu 4 Mg have a sufficient proportion of silicon crystallites.
  • This hard, wear-resistant structural component is highlighted by chemical and / or mechanical processing stages compared to the matrix consisting of the aluminum mixed crystal and forms a required wing portion.
  • the castability, the poor machinability and the high costs of this alloy are disadvantageous compared to the hypoeutectic and nearutectic alloys.
  • sub- and near-eutectic alloys are applied directly to the raceways as galvanic coatings.
  • this is expensive and Insufficiently stable tribochemically.
  • thermal spray coatings which are also applied directly to the running surfaces. This creates a constant negative pressure so that the plasma mist is extracted.
  • layers with a partially high porosity content are applied with different thicknesses.
  • DE 195 35 078 A1 proposes a method for monitoring and controlling thermal spraying methods for coating the surface of substrates, in which a surface temperature of the substrate is measured during the spraying process as a parameter for the transferred layer mass or layer thickness and in the event of a deviation from the target value, at least one process parameter is changed, which is decisive for the transferred layer mass or the layer thickness.
  • the present invention has for its object to provide an improved method and an improved device of the type mentioned above, wherein the disadvantages mentioned above are overcome and in a simple and reliable manner a uniform layer application with constant porosity is achieved.
  • the suction power is changed as a function of the relative movement between the surface treatment device and the surface.
  • the suction device is designed such that it varies the suction power as a function of the relative movement between the surface treatment device and the surface.
  • the surface processing device is, for example, a plasma torch, a coating being applied to the surface by means of plasma spraying and the material mist being sucked off in the form of a plasma mist.
  • the surface processing device is, for example, a laser, the material being alloyed into the surface by means of alloying, or a sprayed layer being applied by application to the surface with the laser, the material mist formed being suctioned off in the form of a particle mist.
  • the suction device comprises, for example, a pump, at least one suction pipe and at least one orifice arranged in the suction pipe, the orifice correspondingly changing a passage cross section of the suction pipe by opening and closing it appropriately for changing the suction power as a function of the relative movement.
  • a constant negative pressure is generated and the suction power is changed by opening and closing the shutters accordingly.
  • a feed device moves the surface processing device relative to the substrate, an adjustment mechanism of the screen being connected to the feed device.
  • the coating or alloy or alloy produced is, for example, a wear-resistant, tribological cylinder running surface of a cylinder of a crankcase of an internal combustion engine for running pistons.
  • the preferred embodiment of a device according to the invention shown in the single FIGURE comprises a plasma torch 10 with a flame 12 and a suction device 14 with a pump 16, two suction pipes 18 and screens 20 arranged in each case in the suction pipes 18.
  • the device shown is used to produce a wear-resistant device , tribological cylinder running surface 22 in a cylinder 24 of a crankcase, not shown, of an internal combustion engine, not shown, for running pistons.
  • the plasma torch 10 is advanced within the cylinder 24 in the direction of arrow 25 and applies the cylinder running surface 22 to a cylinder wall 28 in a coating cone 26.
  • the plasma torch 10 can also be rotated about an axis 32 in the direction of the arrow 30.
  • the plasma torch 10 has in a container 34 a coating powder 36, such as a steel / molybdenum powder, which reaches the flame 12 via a pipe 38. There, the coating powder 36 is heated accordingly and, if appropriate, applied to the cylinder wall 28 surrounded by protective gas 40. This forms a plasma mist 42 of powder not applied, which is sucked off by the suction device 14 via the suction pipes 18, as indicated by arrows 44.
  • a coating powder 36 such as a steel / molybdenum powder
  • the plasma mist 42 is extracted by means of a suction medium, such as air, with a predetermined suction power.
  • suction power here designates a predetermined volume throughput per time of the suction medium through the suction pipes 18, the volume throughput being determined by a negative pressure. The higher the pressure difference due to the negative pressure, the higher the volume throughput of the suction medium, which accordingly tears and sucks the plasma mist with it. On the other hand, with constant negative pressure, the larger the flow cross-section for the suction medium, the higher the suction capacity.
  • a constant negative pressure is generated by means of the pump 16 and the volume throughput in the respective suction tubes 18 is changed by means of the orifices 20 by varying a flow cross section of the suction tubes 18.
  • a control device not shown, which opens or closes the orifices 20 as a function of the feed 25 of the plasma torch 10 in such a way that an exact metering of the suction medium takes place and thus a uniform layer application and a constant porosity over the entire running surface or coating 22 is achieved.
  • the orifices 20 are controlled mechanically or electrically and are connected, for example, directly to a feed device (not shown) for the plasma torch 10.
  • the suction power can be varied individually for each suction pipe 18 with the corresponding aperture 20.
  • the suction power at the suction pipe 18 to which the flame 12 is closer is expediently low is located, and on the corresponding other suction pipe 18, the suction power is increased accordingly.
  • the coating begins, for example, in the figure above, with the suction power being relatively low at the beginning of the suction pipe 18 shown in the figure, in order not to extract any layer components and relative at the lower suction pipe 18 in the figure is high.
  • the suction power at the upper suction pipe 18 is increased by increasing a passage cross section of the upper aperture 20 and reduced at the lower suction tube 18 by reducing a passage cross section of the lower aperture 20 until the lowest point in the coating in the figure or the flame 12, the suction power at the upper suction pipe 18 is highest and at the lower suction pipe 18 is lowest.
  • a constant suction power (according to Bernoulli's equation) and a correspondingly constant layer application is achieved over the entire feed path of the plasma torch 10 in the area of the flame 12.
