Definitions
- the invention relates to a composite material, a composite component of the same and a method for producing a metal-ceramic composite material or a composite component.
- German Patent Application DE 103 50 035 A1 discloses a method for producing a composite component and a metal-ceramic component. This is a metal matrix composite material of a ceramic
- 25 ceramic-metal composites can be used, for example, as so-called casting
- Metal matrix composite in which up to 20% of ceramic fibers or particles are mixed during the production of a metal phase to be cast, or as preform-based metal matrix composite material (MMC pref ), the latter being a ceramic
- Cast metal matrix composites is more wear and corrosion resistant.
- the ceramic starting material of the composite component or composite material comprises a main ceramic component and a ceramic secondary component.
- the ceramic minor component preferably makes up a proportion of between about 0.05% by weight and about 30% by weight, preferably between about 1% by mass and about 3% by mass, of the starting material.
- Interface phase has a good connection to the infiltrated metal.
- the method according to the present invention is particularly suitable for the production of components which, in terms of their thermal conductivity with simultaneous high mechanical stress, for example by friction and Wear, are highly stressed.
- the adaptation of the thermal expansion behavior and excellent damping properties are advantages that can be used with a metal-ceramic composite material according to the invention.
- the maximum operating temperature is suitably higher than 700 0 C.
- a composite component produced by the process according to the invention is distinguished by a high resistance to wear and corrosion, a high damage tolerance and a high thermal conductivity.
- the preform has a porosity of between about 20 vol% and about 70 vol%, preferably from about 40 vol% to about 50 vol%.
- a particularly high strength of the composite component according to the invention can be achieved by a balanced ratio between the preform and the metallic phase and a good connection between the two phases can be achieved.
- a high proportion of ceramics i.
- a porosity of the precursor of about 40 vol% and about 50 vol%, high corrosion resistance and high wear resistance.
- the preform comprises further constituents which are inert to the main ceramic constituent or to the molten metal, wherein in particular the further constituents consist of particles or fibers which are formed from an oxide, a carbide, a nitride or a boride ,
- an oxide is, for example, zirconium dioxide ZrO 2 , in the case of a carbide, for example, silicon carbide SiC, in the case of a nitride, for example, silicon nitride Si 3 N 4 ,
- the inert constituents can be used in particular as reinforcing and / or functional elements for the finished composite component serve.
- silicon carbide or aluminum nitride increase the thermal conductivity of the finished component.
- the ceramic minor constituent comprises at least one oxide and / or a carbide and / or a nitride, in particular
- the preform can be tuned to the particular ceramic main component used as a reactant in an optimal manner. If, for example, used as the main ceramic component Al 2 O 3 and as a ceramic minor component Cu 2 O, forms as bound to Al 2 O 3 interface CuAIO 2 or CuAI 2 O 4 , which also has a good connection with the melt-filtered metal, for Example with pure copper.
- Another object of the present invention is a composite material and a composite component thereof, in particular a brake disk or a clutch friction body or a mechanical seal, with a ceramic, pore-forming phase and with a metal, located in the pores phase, wherein the composite component has a mechanical strength greater than about 500 MPa and has a thermal conductivity greater than about 100 W / mK, preferably has a mechanical strength of greater than about 600 MPa and a thermal conductivity of greater than about 120 W / m K.
- the composite component according to the invention or the material according to the invention is advantageously used in a large number of application areas.
- a high thermal conductivity is especially for tribologically highly stressed components of large
- a porous ceramic preform having an arbitrary shape is produced.
- the shape of the preform is, for example, the typical shape of a brake disk, but it can also be a different shape.
- the preform has a porosity of about 20 vol% or about 30 vol% or about 40 vol% or about 50 vol% or about 60 vol% or about 70 vol%. The range varies, for example, between about 20 vol% and about 70 vol%, preferably between about 40 vol% and about
- a metal-ceramic material is produced by the production method according to the invention, wherein during the production steps the attachment of a preferably highly heat-conductive metal phase to a preferably highly wear-resistant ceramic phase is effected.
- the metal phase preferably comprises pure copper or another, preferably highly heat-conductive metal, essentially in pure form or in an alloy.
- a secondary constituent to the ceramic ie the starting material, is added. This reacts during the sintering process or during the melt infiltration with the main ceramic component, so that forms an attached to the main ceramic component interface phase with an advantageous attachment to the melt-infiltrated metal phase.
- Cu 2 O is provided as the ceramic secondary constituent (the ceramic phase or the precursor).
- This ceramic secondary constituent is present according to the invention in a proportion of about 0.05% by mass to about 30% by mass, preferably from 1% by mass to 3% by mass, in the ceramic starting material.
- the interface phase in particular comprises CuAIO 2 or CuAl 2 O 4 in the event that the main ceramic component (the starting material) is an aluminum oxide, for example an Al 2 O 3 .
- the ceramic starting material consisted essentially of Al 2 O 3 an admixture of 2 mass% Cu 2 O.
- Cu 2 O reacted with Al 2 O 3 to the phase CuAIO 2 .
- the ceramic preform had a porosity of 50 vol%.
- the preform was infiltrated with a pure copper melt in the so-called squeeze-cast method.
- the mechanical strength of the obtained Cu-MMC material or composite component was determined to be 720 MPa.
- Thermal conductivity was determined to be 143 W / mK.
- the invention is not limited to the embodiments described above and in particular not to the production of brake discs. Instead, a large number of ceramic preforms can be used with a form adapted to the particular application.
- the ceramic starting material must have a ceramic secondary constituent which reacts with the main ceramic constituent during the sintering process or during the melt infiltration to form a phase bound to the main ceramic constituent. This must then also have a connection to the infiltrated metal phase.
