An application step of applying an adhesive agent to an application area of a surface of a sintered R-T-B based magnet work, an adhesion step of allowing a particle size-adjusted powder that is composed of a powder of an alloy or a compound of a Pr—Ga alloy which is at least one of Dy and Tb to the application area of the surface of the sintered R-T-B based magnet work, and a diffusing step of heating it at a temperature which is equal to or lower than a sintering temperature of the sintered R-T-B based magnet work to allow the Pr—Ga alloy contained in the particle size-adjusted powder to diffuse from the surface into the interior of the sintered R-T-B based magnet work are included. The particle size of the particle size-adjusted powder is set so that, when powder particles composing the particle size-adjusted powder are placed on the entire surface of the sintered R-T-B based magnet work to form a particle layer which is not less than one layer and not more than three layers, the amount of Ga contained in the particle size-adjusted powder is in a range from 0.10 to 1.0% with respect to the sintered R-T-B based magnet work by mass ratio.

Apparatuses and methods for producing covetic materials by exciting a hydrocarbon gas with pulse microwaves to form hydrocarbon radicals in a hot first region of a microwave reactor. Graphene nanoplatelets are formed by the nucleation, growth and assembly of the hydrocarbon radicals, and contact a metal melt introduced downstream of the hot region to produce a mixture of molten metal and graphene nanoplatelets which assemble in-flight to form covetic materials. Graphene planes are infused in the metal matrix to achieve carbon loadings of at least 60%.

Systems and methods of additively manufacturing multi-material electromagnetic shields are described. Additive manufacturing processes use co-deposition to incorporate multiple materials and/or microstructures selected to achieve specified shield magnetic properties. Geometrically complex shields can be manufactured with alternating shielding materials optimized for the end use application. The microstructures of the printed shields can be tuned by optimizing the print parameters.
