摘要： Carbon-ceramic brake discs, the remaining porosity in which, after infiltration with a carbide-forming element and reaction of this element with at least part of the carbon in the preliminary body of the carbon-ceramic brake disc to form carbides, is at least partly filled with particles whose average diameter is in the range from 0.5 nm to 20 nm, and a process for producing carbon-ceramic brake discs with reduced porosity, wherein carbon-ceramic brake discs are treated with a solution of organic compounds of boron, zirconium, titanium, silicon or aluminum or mixtures of such compounds, the cited organic compounds being present as sols in an organic solvent, after removal from the sol bath the brake discs treated in this way are dried in an oven at a heating rate of between 30 K/h and 300 K/h under air or protective gas and are then tempered at a final temperature of between 350° C. and 800° C. for between 20 minutes and 120 minutes

摘要： A molded part of a ceramic material derived from polymers includes a composite body of a single-phase or multi-phase, amorphous, partially crystalline or crystalline matrix of silicon carbide (SiC), silicon nitride (Si3N4), silicon dioxide (SiO2) or mixtures thereof. The matrix contains graphite inclusions and the density of the ceramic material is at least 85% of the theoretical value. The molded part is produced by subjecting a mixture formed of a polymer component in an amount of 30 to 80 wt. % referred to the total weight of the mixture, fillers in an amount of 0 to 30 wt. % and graphite in an amount of 10 to 70 wt. %, to a forming process with heating to effect crosslinking of the polymer components, followed by a pyrolysis process. In particular, the molded parts are produced from polymers of the group including polysilanes, polysiloxanes, polysilazanes or polycarbosilanes. A process for producing ceramic molded parts and a sliding element having a molded part are also provided.
