Definitions

  • the present invention relates to a method for joining at least one first inorganic molded article produced by injection molding from powder injection molding compositions with at least one second inorganic molded article produced by a method other than injection molding and the use of this method.
  • the molded articles produced by the known method have the advantages over other production methods, among others, that there is a wide range of available materials, that complex geometries can be produced and that close tolerances can be achieved without post-processing (accuracy approx. +/- 0.3% ) and good surfaces can be achieved.
  • DE-A-101 27 626 discloses a method of joining two elements, wherein the first element is made by injection molding.
  • the object of the present invention is to provide an improved method for permanently connecting inorganic moldings produced by injection molding of powder injection molding materials with inorganic moldings produced by methods other than injection molding.
  • an inexpensively feasible cohesive connection of these moldings is to be made possible while reducing manufacturing costs.
  • first a first inorganic molded body is produced by injection molding from powder injection molding compounds.
  • the first inorganic shaped body may be a metal body.
  • the powder injection molding compounds are, for example, in the form of injection-moldable granules containing both an inorganic powder (for example metal powder) and a binder.
  • the preferred injection molding compound used is a product from the Catamold® product range from BASF AG, Ludwigshafen, Germany.
  • Such injection molding compounds are known, for example, from DE 197 00 277 A1 or DE 40 21 739 A1.
  • standard machines for thermoplastic injection molding can be used. If necessary, the injection molding machine to the Material properties of the powder injection molding material of the first inorganic shaped body to be adjusted, for example, by special screw geometries or nozzles, by installing a return flow block or by increasing the wear protection.
  • the first inorganic shaped body is debindered.
  • Debinding is understood as meaning the removal of the binder from the first inorganic molding (green body) produced by injection molding.
  • the debinding method depends on the binder contained in the powder injection molding compound.
  • binder systems with thermally decomposable binders in particular waxes. These are removed from the first inorganic shaped body by a thermal debinding method (melting out or decomposing via the gas phase).
  • thermal debinding method melting out or decomposing via the gas phase.
  • solvent extraction removes the binder with solvents such as water or acetone.
  • the most common method is catalytic debinding, which allows for short debinding times.
  • the Catamold® powder injection molding compounds from BASF AG contain polyacetal as a binder.
  • polyacetal can be depolymerized in non-molten state in gaseous components and thus remove without residue from the injection molded part. This is made possible by the special chemical structure of the polyacetal.
  • Polyacetal unlike polyethylene, is characterized by recurrent carbon-oxygen bonds. At the oxygen atom of this group, acids can attack and split the macromolecule into the basic building blocks CH 2 O (formaldehyde).
  • the catalyst used is preferably gaseous nitric acid (> 99%).
  • the particular suitability of this chemical reaction for debindering in powder injection molding is to be seen in the conditions under which it takes place.
  • the polymer has a melting temperature of about 165 ° C. Debindering takes place well below the melting point at 110 to 140 ° C.
  • the reaction proceeds in the form of a front from outside to inside through the part to be debinded. In the reaction, the polymer goes directly from the solid to the gas state. The reaction gas can thus easily escape through the already porous shaped body zones. A pressure build-up and the resulting destruction of the molding can be avoided.
  • the resulting monomer has a boiling point of -21 ° C and is thus under degassing conditions in any case gaseous. In principle, a 100% debinding could be achieved in this way.
  • the debindered first inorganic shaped body is called a Braunling.
  • step c) of the process according to the invention a sintering process is performed with the assembled first and second inorganic moldings.
  • the second inorganic molded article is an inorganic molded article produced by a method other than injection molding, for example, a molded article produced by press-sintering, casting, forging, milling or turning.
  • Sintering is a heat treatment process in which the loose powder structure of the debindered first inorganic shaped body (Braunling) is compacted into the finished component and simultaneously bonded to the second inorganic shaped body.
  • a thermally activated material transport takes place, which leads to a decrease in the specific surface area of the inorganic powder particles.
  • the first inorganic shaped body shrinks during sintering in step c) of the method according to the invention.
  • particle contacts between the particles of the first inorganic shaped body and of the second inorganic shaped body are produced by the sintering process at contact surfaces of the molded bodies assembled before the sintering process is carried out. The result is a cohesive bond between the two moldings.
  • the inventive method thus allows the cost-effective combination of inorganic injection molded articles with inorganic non-injection molded articles in large quantities.
  • the first inorganic shaped body and the second inorganic shaped body can be combined in the present invention before step b) of the method according to the invention or before step c) of the method according to the invention. If the shaped bodies are assembled before step b), they jointly pass through the debinding step b).
  • the process steps b) and c) according to the invention are carried out in two different furnaces (debinding and sintering furnace) or successively in a single furnace.
  • the joining of the shaped bodies before step b) has the advantage that the brittle brown compact (the debinded first molded body) no longer has to be moved individually before carrying out the sintering process and thus avoiding possible breakage of the brown compact.
  • the inorganic sinterable powder A can be selected from any known suitable inorganic sinterable powders. Preferably, it is selected from metal powders, metal alloy powders, metal carbonyl powders, and mixtures thereof.
  • metals which may be present in powder form are iron, cobalt, nickel and silicon. Alloys are, for example, light alloys based on aluminum and titanium and alloys of copper or bronze. Hard metals such as tungsten carbide, boron carbide or titanium nitride are also suitable in combination with metals such as cobalt and nickel. Suitable powders are described, for example, in EP-A 0 465 940, EP-A 0 710 516, DE-A 39 36 869, DE-A 40 00 278 and EP-A 0 114 746 and the literature cited therein.
  • the particle sizes of the powders are preferably 0.1 to 50 ⁇ m, more preferably 0.2 to 8 ⁇ m.
  • the metal powder, metal alloy powder, Metallcarbonylpulver can also be used in a mixture.
  • component C dispersing aid may be selected from known dispersing aids.
  • examples are oligomeric polyethylene oxide having an average molecular weight of 200 to 600, stearic acid, stearic acid amide, hydroxystearic acid, fatty alcohols, fatty alcohol sulfonates and block copolymers of ethylene and propylene oxide, as well as particularly preferred polyisobutylene.
  • Polyisobutylene is particularly preferably used in an amount of 1 to 6% by volume, based on the components A, B and C.
  • thermoplastic compositions may also contain conventional additives and processing aids which favorably influence the rheological properties of the mixtures during the shaping.
  • the at least one second inorganic shaped body contains at least one material from the group of low-alloyed steels, stainless steels, tool steel, soft magnetic alloys, light metals, heavy metals, copper base materials or precious metals.
  • This sintering process is particularly suitable for powder injection molding compounds from the Catamold® product range from BASF AG.
  • the sintering process must be adapted to the respective material to be sintered.
  • the temperature program mentioned above it is taken into account that, after debindering in step b), there is still a small proportion of residual binder in the first inorganic shaped body.
  • the maximum sintering temperature to be achieved depends on the material of the first and second inorganic shaped bodies.
  • the sintering process preferably takes place in inert gas or in a vacuum.
  • the protective gas atmosphere or the vacuum are necessary to prevent unwanted chemical reactions during sintering. When selecting the atmosphere, all should be possible between the gas, the sintered material and the furnace Reactions are considered.
  • Possible shielding gases are hydrogen, argon or nitrogen or a mixture thereof.
  • a lubricant is applied to at least portions of the mating surfaces of the assembled first and second inorganic moldings prior to step c).
  • the lubricant is used to ensure the shrinkage of the first inorganic shaped body during the sintering process without hindrance and without an undesirable at certain points cohesive connection of the moldings.
  • the lubricant is therefore applied before the sintering step on surface portions of the moldings, which touch after their joining, but should not be firmly connected by the sintering, but on which the first inorganic molded body slides by the shrinkage during sintering.
  • a necessary property of the slip aid is therefore its sliding action at the maximum sintering temperature (second holding temperature).
  • Preferred lubricity aids for the process according to the invention are boron nitride, molybdenum sulfide or molybdenum disulfide.
  • a polymer film is interposed between certain surfaces to be sintered together.
  • the polymer film can fulfill various functions. It can provide a better bond between the first inorganic molded article and the second inorganic molded article because it has a melting point lower than the maximum sintering temperature and thus exhibits an adhesive effect between the molded articles during the sintering process. It can also release carbon, which diffuses into the surfaces of both moldings, reduces the melting temperature there and thus enables sintering closer to the melting temperature.
  • the polymer film can be selected from any known suitable polymer film. Preferably, it contains a polymer from the group polyethylene (PE), polypropylene (PP) or polyvinyl chloride (PVC).
  • the present invention further includes the use of the inventive method for the production of transmission parts, gears, jewelry, levers, nozzles, covers, pump parts, electric motor parts, ball bearings, valves, weapon parts, sports equipment, household appliances, medical equipment, tools or parts thereof.
  • the use of the method according to the invention is not limited to the production of said workpieces.
  • Figure 1 shows in Figure i a section through two moldings, which are to be firmly connected to each other by means of the method according to the invention.
  • the first inorganic shaped body 1 is an annular workpiece, which is present in FIG. 1 as a green compact, that is to say produced by injection molding from a powder injection molding compound, or which is present as a brown compact, that is to say already debinded.
  • the powder injection molding material was, for example, an injection-moldable granulate for the production of sintered moldings from a low-alloy, case-hardenable steel of the type 8620.
  • the second inorganic molded part is, for example, a forging of high alloy steel. It has a cylindrical section 3 whose radius is smaller than the radius of the first inorganic molded part 1.
  • the two moldings 1 and 2 are joined together.
  • the annular first molded body 1 surrounds the cylindrical portion 3 of the second molded body 2, the symmetry lines 4 of the two molded bodies 1, 2 coinciding. If the first molded body 1 is still a binder-containing green compact, the binder removal is carried out according to the method according to the invention in the assembled state of the two molded bodies 1, 2 according to FIG. 2 of FIG. 1 before the sintering process begins.
  • the sintering process can be carried out next after the two shaped bodies 1, 2 have been assembled.
  • a (not shown) polymer film is preferably applied before sintering, which is consequently located between the sixteenzusinternden surfaces 6 and 7 of the two moldings 2 and 1 respectively.
  • FIG. 1 shows the molded bodies 1, 2 connected according to the method according to the invention after the sintering process has been carried out.
  • Shaped body 1 is "shrunk" onto the cylindrical section 3 of the second molded body 2 during sintering and sintered together with it on the surfaces 6, 7.
  • the thus manufactured workpiece 8 is for example a gear part.
