Definitions

  • the invention relates to a method for producing a cylindrical running surface.
  • a cylindrical running surface is, for example, from the article from Hans Rininger "Flame-sprayed plain bearings” from “Der Maschinen nom” (1954, No. 7, page 6 ) known.
  • Sawtooth grooves or threads with longitudinal grooves are made in the cylindrical running surface in order to ensure a non-rotating adhesion.
  • This type of pretreatment has proven to be unsuitable in particular in the case of methods for applying a wear layer with a focus and the associated high local heat input.
  • a wear layer made of an Fe-based alloy to the light metal alloy Additions such as C, Mn, Mo, V etc., an Al-based alloy with additives such as Si, Fe, Cu, Ni etc. or a copper / nickel alloy is applied.
  • the wear layer is preferably applied by welding, plasma spraying, flame spraying or high-speed jet spraying.
  • the light metal alloy to be coated is roughened by a blasting process.
  • this type of pretreatment is very complex due to the blasting systems to be used and only creates an undefined surface structure that causes an uneven introduction of stress into the wear layer, which leads to The consequence is that adequate adhesion of the wear layer is not guaranteed in all load cases.
  • a method for pretreating and coating an inner cylinder bore surface of an aluminum workpiece in which the surface is first honed in different directions, so that initially grooves or scratches arise in the microscopic area, which are to be bent over randomly by further honing, whereby folds and undercuts are to arise.
  • the adhesion of such microscopic layers to the subsequent coating is low.
  • the present invention is therefore based on the object of providing a remedy for the problems outlined above.
  • This object is achieved by a method in which, in a first step, macroscopic circumferential grooves or helically extending thread-like profiles are produced in a cylinder bore or cylinder liner made of a light metal alloy by spinning, cutting or milling, in a second step by a forming process undercuts are generated and in a third process step by welding onto the machined cylinder bore or cylinder liner or by plasma spraying, flame spraying or high-speed jet spraying of the machined cylinder bore or cylinder liner, a wear layer is applied in such a way that partial flanks facing a coating tool are applied in the circumferential direction extending grooves or helically extending thread-like profiles an angle of incidence of the media jet of the coating tool on the partial flanks of almost 90 ° au wise.
  • This claw structure initially leads to a defined enlargement of the adhesive surface of the running surface to be coated.
  • the subsequent coating process results in a higher energy load in the tips, which partially leads to a reproducible diffusion compensation of the wear layer with the base material.
  • the distance to the surface to be coated is so small, especially with diameters of 60-120 mm, that maximum acceleration cannot be achieved in the coating medium; the adhesion is reduced due to the low kinetic energy.
  • optimum adhesion is achieved when the surface to be coated is hit vertically.
  • the angle of incidence of the media jet in cylinders with a diameter of 60-120 mm in the lower cylinder area is significantly less than 90 °, which results in poor adhesion of the coating medium in this zone.
  • connection-like structures are created in zones. It is therefore advantageous according to the invention for the coating process that partial flanks of the claw structure directed towards a coating nozzle are adapted in such a way that the angle of incidence of the media jet of the coating tool is almost 90 °.
  • the macroscopic surface structure specifically produced in this way can be in the form of grooves, preferably extending in the circumferential direction, or also of spiral-shaped, thread-like profiles. Furthermore, the adhesion is improved according to the invention in the radial and / or axial direction by undercuts.
  • Electromagnetic focusing of the media jet significantly increases the energy (pinch effect) per unit area, which leads to an improvement in the layer adhesion.
  • Figure 1 shows a longitudinal section through a cylindrical running surface designed according to the invention.
  • the cylindrical running surface 1 consists of an aluminum alloy known per se.
  • the claw structures 2 according to the invention can also be introduced into the cylindrical running surface 1 in various other ways, such as spinning, cutting, milling, etc.
  • the slight undercuts 4 shown in the present exemplary embodiment are attached to the claw structures 2 by a subsequent forming process.
  • a wear layer 3 was then applied to the cylindrical running surface 1 by plasma spraying. The connection in the area of the thread profile 2 can be clearly seen.
  • FIG 2 A schematic representation of the machining process for applying one of the wear layers 3 by the media jet 5 is shown Figure 2 .
  • the claw structure 2 ensures that the angle of incidence of the media jet 5 is almost 90 °.
  • Figure 3 a first embodiment of the structure 2, which ensures this defined angle of incidence.
  • the alignment of the partial flanks 6 is constant over the entire cylindrical running surface 1, which means that the media jet 5 is moved translationally along the longitudinal axis of the cylindrical running surface 1 during the coating process (see dash-dotted lines).
  • Figure 4 shows a claw structure 2, the partial flanks 6 of which have a steadily decreasing setting angle ⁇ in the longitudinal direction of the cylindrical running surface 1.
  • a claw structure 2 can be produced in a known manner, for example by a CNC machine.
  • the media jet 5 then only needs to execute a rotary movement, as shown, which in turn leads to a simplification of the machining process.
