  • thermal spraying methods can be used.
  • cylinder inner surfaces i. Cylinder-crankcase piston liners are suitable for thermal spray coating.
  • the relatively thin spray coatings offer advantages, especially in aluminum cylinder crankcases, compared to conventionally used cast iron liners, as residual stresses are reduced, overall weight is reduced, and lower friction between pistons and piston liners during engine operation.
  • high thermal and kinetic energy processes are used, such as plasma spraying, wire arc spraying, laser spraying or flame spraying.
  • additional reactive gases may be added to assist the process.
  • the spraying materials used are introduced into the energy beam either as wire or as powder, and thrown onto or into the substrate. Suitable materials are pure substances, alloys or mixtures of different compositions.

  • a method for appropriate preparation of the cylinder inner wall before the coating is z. B. in the WO 2010/015229 A1 described.
  • part of the particles bounces off the inner wall and settles on other component parts as an undesirable layer of dirt or leaves the treatment plant together with the exhaust gases. This contamination can negatively affect the process, the plant and the product.
  • the suction device is composed of two coaxial suction tubes, whereby a radially inner and a radially outer suction opening are created with different suction sources are connected.
  • the suction takes place both to one side and to the other end of the thermally coated cylinder inner surface.
  • the suction power of the two suction lines is controlled in dependence on the respective longitudinal position of the coating tool.
  • the invention is therefore based on the object to provide a device particularly suitable for use in multi-cylindrical crankcases, with which can be safely removed from the workpiece during the thermal spraying of the cylinder crankcase accumulating gases and dusts.
  • a tool shaft carrying the coating tool is passed through the suction device, wherein the suction opening annularly surrounds the tool shank, and that a second suction device, which is part of the workpiece holder, a plurality having suction openings, each of which is associated with one of the suction opening of the cylinder of the crankcase.
  • the gases and dusts accumulating during thermal spraying of cylinder crankcases can be reliably removed from the workpiece, that is to say the cylinder inner surfaces of the multi-cylinder crankcase.
