Definitions

  • the invention relates to a method for producing castings with ceramic embedded in composite form, and to castings which are produced by means of such a method.
  • first phase being formed by a base material and a second phase — in a special spatial arrangement — being embedded in the first phase.
  • the base material is often metallic (pure metal or alloy) and the deposits are made of ceramic material.
  • dispersion alloys dispersion-hardened materials
  • the first phase serves as a binder for the ceramic particles of the second phase, which, in terms of volume, makes up the main part of the composite.
  • Cermets are manufactured using powder metallurgy. They are suitable as wear-resistant materials.
  • the ceramic reinforcement of the cast must be provided in the webs, in the area that is worn away by the wear processes.
  • the ceramic inclusions have a macroscopic character in the castings according to the invention.
  • the casting according to the invention is carried out by means of an investment casting process in which meltable or burnable models are used for the production of the molded shell.
  • meltable or burnable models are used for the production of the molded shell.
  • wax is used for the unreinforced parts of the casting wax with advantage for the model.
  • the porous ceramic bodies intended for the reinforcement are integrated into the cast model, the pore spaces of the ceramic bodies being filled beforehand with wax - or instead of wax with a plastic which volatilizes without residue when the molded shell is fired.
  • the porous ceramic body which has a completely communicating pore space and whose ceramic structure forms a three-dimensional network, can be produced in various ways. Three examples of these manufacturing processes are described below.
  • the following ceramic structures result from these processes: 1. a pile of granular particles; 2. a ceramic structure consisting of rib-like and sintered grain-like particles; 3. a ceramic structure with an open-cell foam structure.
  • the base material used is advantageously a stainless steel, as is customary when casting such plates (ASTM CB-30 or X 35 CrMo 17).
  • Nickel-based or cobalt-based alloys can also be used.
  • the ceramic material must be inert to the melt.
  • aluminum oxide (corundum), zirconium oxide or magnesium oxide can be used; Silicon carbide, on the other hand, is unsuitable because this substance reacts with the melt.
  • a refiner plate 1 with webs 10 is shown in detail in FIG.
  • the web surface 15 (the grinding surface) is subjected to wear during the milling of the fibrous material.
  • the wear areas of the webs 10 consist of a steel / ceramic composite 20, in which a porous ceramic body 2 is embedded in cast steel.
  • the base body 11 of the refiner plate 1 and the web base areas have no embedded ceramic; this maintains the high toughness of the cast material in the web roots, where large bending moments occur during grinding.
  • the cross-sectional drawing in FIG. 2 shows part of the molded shell 30 (including a cast model with a base body 11 'and a wax-filled ceramic body 20').
  • the casting is advantageously carried out in the position shown in order to obtain a good filling of the pore space of the ceramic body 2 by the melt.
  • a ventilation duct 12 see FIG. 3, is provided below the webs 10, the air displacement from the pore spaces improves.
  • the poured channel 12 is, of course, removed during the reworking of the casting.
  • the molded shell 30 is heated before casting to at least a temperature customary for precision casting (around 1150 ° C.).
  • the melt whose liquidus temperature is between around 1300 and 1400 ° C, is overheated. As experience has shown, the pore spaces of the ceramic bodies 2 fill completely thanks to the overheating before the solidification of the melt occurs.
  • FIGS. 4, 5 and 6 relate to the production of a first porous ceramic body 2
  • Ceramic grains 21 for example corundum, diameter between 0.8 and 1.2 mm
  • a pile 2 'with a pore space 22 is formed.
  • This pore space 22 is filled with a free-flowing binder (eg silicate binder) and then emptied again via the outlet 32, bridges 21a of the binder material being formed between the grains.
  • a coherent ceramic body 2 is obtained, which can be removed from the trough 31 and solidified by firing.
  • the ceramic body 2 is filled with wax and installed in the casting model for the production of the molded shell 30.
  • the wax is removed from the surface 23 of the ceramic body 2, so that a direct connection between the grains 21 and the molded shell 30 is created. After the wax 35 has melted out, there is a connection between the ceramic body 2 and the molded shell 30.
  • a surface 23 is formed with the metallic phase 35 filling the pore space 22, from which tips of the grains 21 emerge.
  • a second porous ceramic body 2 is produced by means of an open-cell foam structure 50 made of plastic, see FIG. 7.
  • the two net layers are connected to one another by invisible rungs.
  • the average distance between adjacent ones Mesh layers can be equated to the average cell diameter, the cell diameter is in the range of around 1 to 5 mm 50 applied.
  • the diving and Subsequent sanding must be carried out several times - for example three times.
  • the resulting rib-like agglomerate of ceramic grains is sintered together by firing, the plastic of the original foam structure 50 evaporating at the same time.
  • this ceramic body 2 is again shown as in FIG. 7 with two net layers 25 and 25 '(on an enlarged scale), the ceramic grains being drawn only for the upper net layer 25, however somewhat too large.
  • the third ceramic body 2 shown in FIG. 9 consists of a commercially available ceramic structure which is used, for example, as a filter for molten metal.
  • the production of this ceramic framework with an open-cell foam structure is known for example from CH-PS 679394.
  • FIG. 9 shows a section through the walls of the ceramic foam structure 26. Thanks to openings 27 in the walls, the cells form a completely communicating pore space 22.
  • FIG. 10 shows the ceramic structure 26 of FIG. 9, the pore space of which is filled with the metallic phase 28 (or with wax or plastic) and forms the composite body 20.
  • the metallic phase 28 is washed out on the web surfaces, as indicated in FIG. 11.
  • the relief-like surface structure probably has an improved fibrillating effect when the pulp is ground.
  • FIG. 12 shows a turbine blade tip 100 with armor 102, which is designed as a casting according to the invention.
  • the Armor 102 is formed by a casting zone with embedded ceramic, while the main part 101 of the blade is an unreinforced casting (for example the product of a method with directional solidification).
