Manufacturing Methods and Technology for Processing Cobalt-Samarium Magnets
Abstract
Alternative manufacturing methods, processes, and techniques for fabrication of cobalt-samarium magnets were evaluated. A pre-production pilot line capable of producing cobalt-samarium magnets was established. The properties of magnets produced on this pre-production pilot line exceed: (BH) sub max 15 MGOe, B sub r 8.2 kG, H sub c -6.5 kOe, H sub d (at B/H = -1/2) -5.0 kOe, and irreversible the loss (at B/H = -1/2) on exposure to 150C less than 10%. The cost of magnets produced on this pre-production pilot line was approximately one fourth the cost the same size magnet would be if fabricated from cobalt-platinum. Magnets produced on this pilot line were used to successfully fabricate five traveling wave tubes. The performance of these tubes indicates that cobalt-samarium magnets are suitable for fabrication of traveling waves tubes; and, in fact, that they will allow further advances in the state- of-the-art in the design of such tubes.
