    Abstract: A component is made, in regions, of a ceramic-metal composite material. A porous sacrificial body produced from ceramic precursors is filled with softened metal and/or a metallic alloy at a predeterminable filling temperature at or above the softening temperature of the filling metal and under superatmospheric pressure. The filled sacrificial body is heated to or above a reaction temperature which is higher than the filling temperature, where a reaction between the filling metal (FMe) and the metal of the ceramic of the sacrificial body (CMe) is carried out, forming the ceramic-metal composite material comprising a ceramic phase and a metallic phase. The ceramic phase comprises CMemBx and/or CMenCy and/or CMeoCN and FMepO3, and the metallic phase comprises an intermetallic compound of a metal of the ceramic (CMe) and a filling metal (FMe). The sacrificial body is filled with the filling metal (FMe) during pressure casting of the component. A shape at least close to the final shape of the component, comprising a filled sacrificial body and the intermediate element(s) free of the sacrificial body, is cast by the pressure casting tool, and the component after casting is complete is heated to or above the reaction temperature in the region of the sacrificial body.

    Abstract: A friction-type member, which is suited, in particular, as a brake pad for a brake member of fiber-reinforced ceramic, and a method for manufacturing such a brake pad. A mixture is initially prepared from at least carbon particles and metal particles, if indicated, with the addition of polymer binding agents suited for pyrolysis; of hard material particles, such as silicon carbide or titanium carbide as abradants; and of solid lubricants, such as molybdenum sulphide or graphite, and subsequently cold-pressed into green compacts. Sintering is then carried out under vacuum or protective atmosphere, the organic binding agent concentrations initially being pyrolized, and the metal particles being at least partially bonded by reaction to carbon. The friction pads manufactured in this manner exhibit considerable mechanical strength, good frictional properties, as well as a high thermal loading capacity accompanied by a low rate of wear.
