Definitions

  • the invention relates to a method for surface preparation of a workpiece with a metallic carrier material according to the preamble of patent claim 1 and a workpiece with a metallic carrier material according to the preamble of patent claim 9.
  • DD-A-242 638 discloses such a method for improving the adhesive strength of metal sprayed layers, in which the component surface is cleaned by melting using a continuous or pulsating laser beam with a specific power density or by controlled thermal exposure.
  • the energy beam is intended to roughen and activate the area near the surface before thermal coating with metal or ceramic.
  • the laser beam is guided in such a way that the traces of melting just touch each other, as a result of which the affected surface area is homogenized.
  • the alignment of the tracks and the speed of movement of a pulsating laser beam are selected in such a way that the zones of influence overlap.
  • the energizing impulses cause contaminants to evaporate or explode and activate the surface.
  • the present invention has for its object to provide a method of the aforementioned type, which allows the surface of the carrier material of a workpiece to be pretreated in such a way that a substrate is formed with an even adhesive strength for a metal or ceramic layer to be sprayed on, which is also possible with a high level Stress on the workpiece shows no cracks or other signs of detachment in the sprayed-on layer.
  • this object is achieved by a method having the features of claim 1 and by a workpiece having the features of claim 5.
  • the invention has the great advantage that an improved mechanical connection or clamping of the sprayed-on metal or ceramic layer with the surface of the metallic carrier material is produced.
  • the process is considerably less expensive than the conventional roughening processes, such as sandblasting, since there is no need for subsequent cleaning.
  • the throughput times in the case of the invention are also Processes significantly lower, which is why it is more economical.
  • Fig. 1 is a schematic representation of a treatment process for surface preparation for the subsequent metal or ceramic coating
  • Fig. 2 cross sections through a part of a workpiece with different types of recesses, the carrier material surface has been prepared with the treatment method explained with reference to FIG. 1.
  • a workpiece 1 here a metallic circular cylindrical hollow body, with its surface 2 and small recesses 3 located therein.
  • the hollow body 1 is rotatably supported in a known manner about an axis of rotation 5.
  • a schematically indicated laser cannon 7 with a mirror 8 is shown to the side of the hollow body 1, with which a laser beam 9 is directed onto the workpiece 1, here the circular cylindrical hollow body.
  • the mirror 8 is mounted in a manner known to those skilled in the art by means of servomotors so that it can rotate in all directions.
  • the depressions 3 are worked into the surface 2 in a predetermined pattern or grid indicated by the arrow 11.
  • the geometric shape of the recesses 3 is the performance control of the laser beam 9 and achieved by the continuous and targeted deflection of the laser beam 9 with the mirror 8 in the desired manner.
  • suitable control of the laser beam 9 almost any geometrical shape of the depressions 3 can thus be obtained in a predetermined pattern or grid.
  • the depressions 3 can be provided on the surface 2 in any pattern, a regular grid is preferred, however, which is formed by the nodes of sets of parallel straight lines which are perpendicular or at an oblique angle to one another.
  • FIG. 2 shows various examples of the depressions 3 produced by means of the laser beam 9 in a cross section through part of a workpiece 1.
  • the metallic carrier material 13 of the workpiece 1 is shown below, on which a metal or ceramic layer 14 applied in the plasma spraying process is anchored.
  • FIG. 2a shows a recess 3 which is frustoconical. The geometric shape shown is achieved in that the mirror 8 is brought to a certain distance from the workpiece 1 and the laser beam 9 is deflected in a predetermined angular range. The aforementioned distance is formed from the apex of a cone through the truncated cone-shaped recess 3. The depth of the recess 3 is in the range from 10 to 100 ⁇ m, in particular between 2 to 10 ⁇ m.
  • the width of the recess 3 is also of the same order of magnitude.
  • the circular-cylindrical depression in FIG. 2b is obtained in that the mirror 8 is continuously shifted in directions perpendicular to the normal to the flat surface of the carrier material 13 while the power density of the laser beam 9 remains the same.
  • the depression 3 in FIG Laser beam 9 reached with such a shift.
  • the depressions 3 shown in FIGS. 2a to 2c are all rotationally symmetrical. This means that the depressions 3 all have a circular cross section. However, it goes without saying that other types of depressions 3 can also be provided, for example with a square or triangular shape in cross section. However, the rotationally symmetrical shape is preferred.
  • the targeted and defined shape of the depressions 3 results in an improved mechanical clamping of the carrier material 13 with the sprayed-on metal or ceramic layer 14.
  • the adhesion of this layer 14 is significantly improved by this measure.
  • the geometric dimensions of the depressions 3 can largely be adapted to the requirements of the required adhesion of the coating material. Subsequent cleaning, as with the mechanical roughening process, such as. such as sandblasting, is completely eliminated.
  • the method described above can also be carried out with an electron beam, which is directed onto the workpiece by electromagnetic means in a manner known to those skilled in the art.
  • the method described is particularly suitable for the production of cylinder liners for internal combustion engines, the depressions 3 preferably being incorporated after a dot matrix 11, as indicated purely schematically in FIG. 1.
