Definitions

  • the invention relates to a metal-ceramic material with a matrix of one Heavy metal or a similar alloy, in particular from a Iron-nickel, molybdenum or cobalt-based alloy, and one in this evenly distributed ceramic phase, the particles of which may be a Wear surface layer.
  • the invention relates to a method for producing a Material of the type mentioned above.
  • Substantially homogeneous materials can by their composition and Treatment, especially thermal or thermomechanical treatment, the Requirements to be adapted to this.
  • the metals used seem to be due to alloy and processing measures achievable property level and the same profile no longer a great opportunity for improvement include.
  • achievable property level no longer a great opportunity for improvement include.
  • stresses on parts Taking into account the use of heterogeneous or composite materials proposed and realized.
  • Composite bodies generally consist of at least two parts have different properties and meet each other as required are preferably permanently connected.
  • the respective parts take over those Strains for which they are particularly suitable.
  • fiber-reinforced composite body is generally known technically and denotes an object consisting of a mostly tough matrix, in which are insoluble high-strength fibers embedded. This item owns consequently advantageous at the same time good toughness and high rigidity and Strength in the direction of the fibers.
  • the Fiber material can consist of oxides, borides, nitrides, carbides and mixed forms the same exist.
  • the ceramic fibers have consistently high temperature resistance as well as strength and rigidity, cause a so-called reinforcement of a less firm, but tough Matrix metal.
  • a correspondingly large length and a similar proportion of Fibers appear to effectively incorporate them into the matrix and the advantageous formation of a property segment of the composite of to be essential.
  • the task is in a generic subject solved according to the invention in that the ceramic phase of short fibers is formed, which has a fiber length of at least 5 times, but at most that 15 times the fiber diameter.
  • the advantages achieved with the invention are essentially to be seen in an isotropy of the material with significantly improved mechanical properties such as high strength and toughness and resistance to temperature changes. It was completely surprising for the experts that short fibers in a heavy metal matrix can bring about a sudden and pronounced improvement in the mechanical properties and that this is present in all directions. If the fiber length reaches a value of less than 5 times the diameter, then essentially no solidification of the material can be achieved; a transition to a dispersion hardening of the material, which is significantly less with the same concentration of ceramic particles, only occurs with a particle size in the range of 1x 10 -1 ⁇ m. Longer lengths than 15 times the fiber diameter promote the anisotropy of the composite material by breaking the fibers in neighboring areas during high compaction.
  • the fibers range in diameter from 0.5 to 14.5 ⁇ m, the reinforcing effect is particularly favorable and Composite material economically feasible. Fibers with a diameter of less than A high proportion of 0.5 ⁇ m can be highly efficient, a homogeneous one However, incorporation into the matrix requires considerable effort. In contrast, fibers with a thickness of greater than 14.5 ⁇ m are increased Risk of breakage during material production exposed.
  • the highest material quality is achieved with a fiber diameter of 0.7 to 9.5 ⁇ m reached.
  • the fiber material consistently has a high melting or Softening temperature and largely temperature-independent moduli as well Has strength values, are at higher concentrations of the same in the Matrix in particular the properties of the composite Hot conditions raised.
  • the material according to the invention for use in undeformed Condition is provided and a fiber content of greater than 20 vol .-%, preferably of greater than 30% by volume, can be used in a favorable manner Parts for high abrasive loads are manufactured.
  • the composite body having a fiber content of at most 30% by volume, preferably less than 20% by volume.
  • the matrix material of the composite material from an iron-nickel-molybdenum or Cobalt-based alloy with high heat resistance, especially from an alloy with a drop in strength at a temperature above 600 ° C, in particular above 615 ° C.
  • the matrix material consists of copper or a copper alloy, can still despite high fiber content and the like mechanical characteristics remarkable heat and electrical conductivity properties of the material can be achieved.
  • HIP process hot isostatic pressing of a homogeneous mixture ceramic fibers made of matrix metal powder with a grain size of 15 to 200 ⁇ m, preferably less than 50 ⁇ m, and optionally carbides with one Grain size of less than 25 microns is created.
  • the further object of the invention is a process for the production of To create metal-ceramic materials, according to the invention achieved that ceramic fibers as short fibers with a fiber length of at least 5 times, but at most 15 times the Fiber diameter created and with one or more ultimately the matrix forming metal powder with a grain size between 15 and 200 microns and if necessary, mixed homogeneously with a hard material powder and directed on all sides are distributed, whereupon the mixture thus created is sintered.
  • the process advantages according to the invention can be seen in particular in that the miscibility of the components is improved so that a homogeneous Distribution of the short fibers can be achieved with less time. Furthermore, there is an all-round alignment of the short fibers and thus a creation good conditions for the production of isotropic material on simple Possible way, smaller grain sizes of the powder have an advantageous effect can. Due to the short fiber length, the mixture can also have a high density in the event of vibration, a so-called high tap density, in the capsule in front of the Sintering can be achieved. When sintering itself, however, they are slightly longer Sintering times apply because higher fiber shares the temperature conduction of the Mix lowered.
  • a particularly high quality of the composite material can be achieved if short fibers with a diameter between 0.5 and 14.5 microns, preferably from 0.7 to 9.5 ⁇ m, and a fiber length of preferably at most 12 times the Diameter and with the metal powder that ultimately forms the matrix, which preferably has a grain size of less than 50 microns, mixed and be sintered.
  • the metal-ceramic body as a metal powder those made of tool steel, preferably high-speed steel, are used from this high quality tools with compared to conventional products superior cutting and wear resistance properties can be produced. Such Quality increases can also be achieved with non-cutting tools become.
  • the mixing of the short fibers with the Metal powder (s) and / or filling a container or a capsule for a subsequent sintering is (are) carried out under a nitrogen atmosphere a largely pore-free sintering favors.
  • the one between the fibers and the Metal powder grains of nitrogen trapped in the blank stand, as found was in interaction with the non-metallic and metallic elements and is ultimately used in the metallic Matrix solved, which on the one hand promotes the sintered density and on the other hand benefits fiber embedding.
  • the time required can be further reduced, when the mixture is sintered under pressure.
