FIELD: physics.
SUBSTANCE: method of obtaining textured coatings with anisotropic coercitive force based on magnetic compounds involves synthesis of magnetic composite powders. To this end, strontium hexaferrite magnetic powder is uniformly placed in a channel on the surface of deformed metals and alloys and premoulding is performed. Milling is then carried out with a protective interlayer of titanium foil between the powder and mill rolls in a temperature interval from 20°C to 600°C, with subsequent annealing at temperature of 800-850°C or not less than 2.5 hours.
EFFECT: invention increases coercitive force and degree of anistropy thereof in magnetic coatings based on strontium hexaferrite.
