Abstract
Official abstract text for this publication.
A system for making a material having domains with insulated boundaries is provided. The system includes a combustion chamber, a gas inlet configured to inject a gas into the combustion chamber, a fuel inlet configured to inject a fuel into the combustion chamber, an igniter subsystem configured to ignite a mixture of the gas and the fuel to create a predetermined temperature and pressure in the combustion chamber, a metal powder inlet configured to inject a metal powder comprised of particles coated with an electrically insulating material into the combustion, wherein the predetermined temperature creates conditioned droplets comprised of the metal powder in the chamber, and an outlet configured to eject and accelerate combustion gases and the conditioned droplets from the combustion chamber and towards a surface such that conditioned droplets adhere to the surface to form a material having domains with insulated boundaries thereon.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for making a material having domains with insulated boundaries, the method comprising: creating conditioned droplets from a metal powder made of metal particles coated with an electrically insulating material at a predetermined temperature and pressure; and directing the conditioned droplets at a surface such that the conditioned droplets create materiel having domains with insulated boundaries thereon. 2. The method of claim 1 in which the particles of the metal powder include an inner core made of a soft magnetic material and outer layer made of the electrically insulating material and the step of creating conditioned droplets includes the step of softening and partially melting the inner core while providing a solid outer core. 3. The method of claim 1 in which the conditioned droplets are directed at a stage at a predetermined speed. 4. The method of claim 3 further including the step of moving the surface on a stage in one or more predetermined directions. 5. The method of claim 4 further including the step of providing a mold on the surface.
