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.
Claims6
A method of forming a metal ring structure of alternating segments of two different metal materials, which comprises providing a ring of a first metal material having teeth, plasma arc cleaning the outer surface of said ring to prepare the outer surface for plasma deposition of a second metal material, plasma spray depositing said second metal material on the outer surface of said ring to fill in the troughs between the teeth, enlarging the inner diameter of the ring by removing the material to form a ring having alternating segments of said first metal and said second metal materials.
