Method for manufacturing friction discs made of ceramic materials with an improved friction layer

Manufacturing friction discs from ceramic materials comprises preparing a mixture of fine-particulate silicon and/or fine particles of other carbide-forming elements with at least another component such as a resin in particulate form and a binder from synthetic resins and/or pitches; degassing the mixture, pressing to a cylindrical or cylindrical ring-shaped disc and hardening at up to 280[deg] C; heating the hardened disc at approximately 750-1300[deg] C; heating the remained porous carbon body; and adding additional silicon. Manufacturing friction discs from ceramic materials with at least a friction lining, whose matrix contains silicon carbide, silicon and carbon comprises preparing a mixture of fine-particulate silicon and/or fine particles of other carbide-forming elements with at least another component such as a resin in particulate form and a binder from synthetic resins and/or pitches; degassing the mixture, pressing to a cylindrical or cylindrical ring-shaped disc and hardening at up to 280[deg] C; treating the hardened disc by heating at approximately 750-1300[deg] C under the absence of oxidizing agents, where the binders decomposes under the formation of a carbon residue, and a porous carbon body remains; heating the porous carbon body up to the melting temperature of the silicon or other carbide-forming elements, where these react with the formed carbon and give rise to an alveolar structure with a skeleton made of the formed carbides and non-reacted residues of carbon or the carbide-forming elements; and adding additional silicon at a temperature above its melting point, where at least a part of the pores of the structure is filled with elemental silicon, and non-reacted carbon of the alveolar structure reacts with silicon to form silicon carbide.
