Definitions

  • the present invention relates to a material for tribological applications according to the preamble of claim 1.
  • MMC Metal-Matrix Composites
  • Preform MMC materials are more resistant to corrosion and wear than cast MMC materials.
  • Brake discs and brake drums have been made from cast-MMC aluminum-based materials since 1997.
  • the rear axle brake drums of the VW small car model Lupo 3L are made of a material with the brand name Duralcan. This material is composed of 80% by volume of an aluminum casting alloy and 20% by volume of ceramic particles (SiC) and is produced by the so-called "stir-casting" process described in US Pat. No.
  • Object of the present invention is therefore to provide a material for tribological applications, in particular as a brake disc or drum, which despite high weight has a high temperature resistance and also ensures a significant improvement in wear and corrosion resistance.
  • a metal-ceramic composite material is provided in particular for tribological applications, comprising a preform made of a ceramic material, as well as a metal component copper or a copper alloy, the proportion of ceramic ranging between 30 and 80 vol.% And the proportion of Copper or copper alloy ranges between 20% and 70% by volume.
  • the significantly higher achievable ceramic content of up to 80% by volume compared with cast MMCs has an advantageous effect on the wear and corrosion resistance of the materials. This leads to a longer service life, higher optical brilliance and improved braking comfort.
  • a significantly higher operating temperature is also possible compared to aluminum-based materials.
  • the materials according to the invention can therefore be used as brake materials for a significantly expanded vehicle segment.
  • the proportion of copper or copper alloy on the metal-ceramic composite is particularly preferably 25-60 vol .-%.
  • the ceramic material used for the preform are oxides (eg TiO 2 , Al 2 O 3 ), carbides (eg SiC, TiC, WC, B 4 C), nitrides (eg Si 3 N 4 , BN, AlN, ZrN, TiN), borides (eg TiB 2 ) and / or silicates in question.
  • the ceramic material is preferably present in the production of the preform in particle or fiber form.
  • these ceramics may also serve as reinforcing or functional elements (e.g., SiC or AIN for improving thermal conductivity, ceramic fibers for improving fracture toughness and strength, etc.).
  • SiC or AIN for improving thermal conductivity
  • ceramic fibers for improving fracture toughness and strength, etc.
  • the preform has a porous ceramic basic structure, into which the copper melt or the molten alloy is infiltrated, an intimate connection between the preform and the solidifying metal results. In doing so, inter- - A -
  • the strength and toughness of the body is further increased.
  • the proportion of ceramic on the metal-ceramic composite is particularly preferably 40-75% by volume.
  • a component for tribological applications in particular in vehicle construction, provided, comprising a metal-ceramic composite material according to one of the preceding claims.
  • brake disks or drums are considered here as components, but also other components which have to endure high mechanical and thermal loads, at the same time have a low specific weight and, moreover, have to be resistant to corrosion, in particular in the automotive, motorcycle and aircraft industries shipbuilding.
  • the components preferably have a thermal conductivity ()> 70 W / m K in order to avoid high thermal gradients or high thermal stresses, which may occur as a result of the high energy input during the friction stress. This is particularly caused by the copper content, since copper has a very high specific thermal conductivity.
  • the strength of the components is> 200 MPa, preferably> 350 MPa. This is where the higher ceramic content compared to Cast-MMCs comes into play.
  • a maximum service temperature of> 800 ° C is desired. This is also achieved by the copper content, since copper and copper alloys have higher melting points than aluminum or aluminum alloys.
  • the porosity of the preform amounts to 20-70% by volume, preferably 25-60% by volume.
  • Porosity is to be understood as meaning the ratio of the volume of all cavities of a porous solid to its outer volume, the cavities being generally networked together and being in exchange or interconnected with the atmosphere surrounding the porous solid (so-called open porosity). It is therefore a measure of how much space the actual solid fills within a certain volume or which cavities it leaves in this volume.
  • the pores are usually filled with air. Due to the porosity of a preform, therefore, the volume fractions of the ceramic and metal components of a preform MMC to be expected later are usually determined.
  • Solidification of the molten metal in the infiltration front must also be ensured that the ceramic preform has one of the melting temperature near temperature, the temperature difference should not be greater than 35O 0 C, preferably not greater than 100 0 C.
  • the casting tool should preferably be preheated, and direct contact between the casting tool and preform should be avoided, e.g. by spacers or lining with an insulating material such as ceramic paper or fleece.
  • An additional measure may be to surround the preheated ceramic preform with an insulating sheath, for example with ceramic paper or fleece or a steel hollow body adapted to the shape.
  • the infiltration with molten metal is reaction-assisted or non-reactive, ie there is only a reaction limited to the surface zone of the ceramic phase or there is no reaction between metal and ceramic. phase instead.
  • the infiltration quality can be improved and the infiltration pressure can be lowered (the cause of this is the released reaction heat or the changed surface tension due to the newly formed interface phase).
  • one or more pore formers are added to the ceramic material prior to sintering. These are usually elongated, easily burnable materials that burn during sintering, creating a network of channels and pores that facilitate subsequent infiltration of the molten metal and allow intimate bonding between the preform and the solidifying metal.
  • the channels produced in this way can have widths of 2 to 50 ⁇ m, preferably 5 to 30 ⁇ m. By the channels filling in the finished body metal channels, the strength and toughness of the body is further increased.
  • the pore formers have a significant influence on the setting of a specific porosity.
  • pore formers can also be used in particular in the production of ceramic preforms in order to produce a network of pore channels, which result in a better infiltrability of the preform; the pore channels act as infiltration channels here.
  • the resulting metal channels increase the strength and toughness of the material.
  • cellulose flakes or fibers having a volume fraction of 1 to 30%, preferably 2 to 20%.
  • pore formers z.
  • Ru ß- particles rice starch or organic macromolecules, such. Fullerenes or nanotubes conceivable.
  • pore formers are all those materials which burn, disintegrate or outgas during sintering, thus creating voids in the material.
  • melt of copper or copper alloy is infiltrated by applying an external pressure.
  • gas pressure infiltration or melt infiltration by means of the known technique of "squeeze casting" are possible here as possible processes
  • the mechanical strength of the obtained Cu-MMC material was determined to be 384 MPa, the thermal conductivity of 91 W / m K.
  • the corrosion rate of this Cu MMC in water at 35 0 C by a factor of 28 lower than in gray cast iron and the wear rate is to 2 orders of magnitude lower than that of gray cast iron.
