Abstract: A method for recycling at least one magnet of an electric machine. A subassembly having the magnet is disassembled from the electric machine. In the process, the following steps are provided: carrying out a first thermal treatment of the subassembly at a first temperature, mechanical separation of the magnet from the subassembly, and carrying out a second thermal treatment of the magnet at a second temperature, which is higher than the first temperature, for debinding and/or cleaning of the magnet.

Abstract: A composite material, a composite component made thereof, and a method for producing a metal-ceramic composite material or a composite component are provided. The composite material or the composite component is produced by the method described in the following. In a first step, a porous ceramic preform is produced from a ceramic starting mass, and in a second step the infiltration of the porous ceramic preform with a molten metal takes place, the ceramic starting mass having a ceramic main component and a ceramic minor component that reacts with this main component, and the minor component reacts at least partially with the main component during the first and/or second step.

Abstract: A method for manufacturing a composite component, a brake disk in particular, and a metal-ceramic component are described. In the method, a porous ceramic blank is produced and infiltrated with a metal melt. An alloy of copper and at least one additional metal is used as the metal melt for infiltration, the additional metal being converted by at least one reactive component of the blank in such a way that a pore space of a ceramic phase is filled essentially with pure copper.

Abstract: Porous coatings on high-performance ceramics attempt to combine the mechanical and thermal characteristics, which fulfil stringent demands, of the substrate material with the advantageous properties of coating materials. The subsequent application of layers of this type to the pre-sintered substrate produces unsatisfactory results in several areas of use with regard to possible layer thickness, porosity and adhesion. According to the invention, a shaped body consisting of a sintered, inorganic material, whose surface comprises a porous layer is produced in such a way that the base body is first formed as a green body. A layer in the form of a suspension, also containing an inorganic material, is then applied to the surface or to one section of the surface of the base body. A predetermined fraction of a pore-forming substance is mixed with at least the material of said layer and the green body with its applied layer is subjected to the thermal treatments required for producing a monolithic sintered body.
