Method to manufacture brake discs with ceramic friction surfaces; involves inserting at least one ceramic part in die casting mould and casting symmetrical body from molten metal under pressure

摘要

The method involves inserting at least one ceramic or ceramic composite part in a die casting mould and casting under pressure with molten metal to form a rotationally symmetrical body. The body contains at least one ceramic segment, which is symmetrical to the rotation axis of the body and projects from at least one surface of the body that is perpendicular to the axis. A ceramic ring disc or two parallel ceramic ring discs may be inserted. An Independent claim is included for a brake disc manufactured according to the method.
