FIELD: electricity.
SUBSTANCE: method includes manufacturing of an alloy based on Nd-Fe-B, its hydrogen embrittlement, coarse grinding and subsequent fine grinding in a vibration mill using toluene as a protective medium. Lubricants are added to toluene before grinding, such as dry powders of aluminium stearates, or copper, or zinc, or ethyl ethers of homological row of carbonic acids. After grinding of the powder to the average size of particles 2.5-3.5 mcm it is loaded in dry or moist condition into a container from molybdenum and/or graphite with charging density from 3.0 to 3.5 g/cm3, and texturing is carried out with a pulse magnetic field with subsequent vacuum sintering of powders along with slow heating to temperature of not more than 500°C.
EFFECT: reduced forces of friction between particles of powder textured in magnetic field with subsequent formation of sintered magnets with high extent of texture by magnetic characteristics.
