Composite Magnetic Particles and Foils

Abstract

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.

1 . A composition comprising coated substrate materials created by the process of: 
 providing to a rotary flow-through electrodeposition cell electrolytic fluid and substrate material particles;    employing an electrode; and    via one or more magnets or electromagnets, drawing substrate material particles in the cell against the electrode.    
     
     
         2 . The composition of  claim 1  wherein said coated substrate materials comprise nanoparticles.  
     
     
         3 . The composition of  claim 1  comprising a composite foil.
