NET SHAPE PROCESSING OF PERMANENT MAGNET BY FIELD ASSISTED SINTERING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17885119 titled 'NET SHAPE PROCESSING OF PERMANENT MAGNET BY FIELD ASSISTED SINTERING
Simplified Explanation
The patent application discloses magnets with various portions of different densities and resistivities, achieved through different physical structures within the same composition. Unique dies are used during processing, such as sintering, to manufacture these magnets. The dies have conductive and non-conductive surfaces that manage the electrical current applied to the magnetic powder mixture, resulting in complex and unique magnets. Methods like spark plasma sintering are also disclosed for manufacturing these magnets.

Original Abstract Submitted
Magnets having various portions of different densities and resistivities are disclosed. In a refinement, the various portions may have the same composition but different physical structures. Unique dies may be used to during processing, such as during sintering to manufacture the magnets. The die may include conductive and non-conductive surfaces that contact the green magnetic powder mixture during sintering such that the electrical current applied to the magnetic powder mixture is managed by the conductive and non-conductive surfaces to provide unique and complex magnets. Methods of manufacturing the magnets with the dies such as field assisted sintering, i.e., spark plasma sintering, are also disclosed.
