ABSTRACT:
The subject rotor comprises a disklike body having hub and rim sections joined by a web section. The body is cast, molded or otherwise suitably formed of powdered silicon (and a binder, if necessary, to make it retain its shape until finally treated) which is reaction bonded to convert the silicon particles into a unitary mass. During the casting, molding or other forming step, one or more reinforcing rings of hot pressed silicon nitride or other suitable ceramic are embedded in the body. The ceramic selected must be one which will unite with the silicon during the reaction bonding operation to make a unitary mass. The reinforcing ring or rings are located in regions exposed to unusual stress in the use of the rotor to achieve the required strength.
