Abstract

A method for the production of brake discs having friction areas made of ceramic materials, in particular composite materials, includes placing at least one ceramic portion in a diecasting mold and joining the ceramic portion with molten metals by casting under pressure into a rotationally symmetrical body which contains at least one ceramic (composite) segment that is disposed symmetrically relative to the axis of rotation of the metal body and juts out over at least one surface of the metal body perpendicular to the axis. A brake disc produced according to the method is also provided.
