ABSTRACT:
A ring is formed having alternating segments of ferromagnetic and paramagnetic materials. The ring is formed by first providing an annular ring of a high strength magnetic steel. Teeth are formed on the outer surface of the ring by forming troughs of the ferromagnetic material. Low pressure plasma deposition is used to fill in the troughs with a high strength paramagnetic material. The excess steel and excess plasma deposited material is removed to leave the finished ring of alternating segments of ferromagnetic and paramagnetic material.
