ELECTRODEPOSITION APPARATUS AND METHOD USING MAGNETIC ASSISTANCE AND ROTARY CATHODE FOR FERROUS AND MAGNETIC PARTICLES

摘要

A method and apparatus for microencapsulating or electrodeposited coating of ferromagnetic and soft-magnetic sub-micron or nano sized powderized material comprising use of a rotary flow-through device assisted by an electromagnet within the electrode ring to alternately position the powder at the face of the cathode ring and electroplate the powder and reorient it prior to another repositioning, The invention is also of a process and apparatus for forming a strip, mesh, or film from magnetic powderized material in an organized bipolar arrangement, which is particularly useful for electroforming foils with the magnetic particles positioned in a monolayer within a multilayer metallic foil.
