FIELD: metallurgy.
SUBSTANCE: sintered magnet of Fe-B-rare earth elements family arranged in working chamber is heated to the specified temperature. Metal material containing at least one of Dy and Tb and arranged in working chamber or evaporation chamber interconnected with the above working chamber through the connecting channel is evaporated, and evaporated metal atoms are deposited to the surface of sintered magnet at control of the quantity of supplied metal atoms. Provision is made for diffusion of deposited metal atoms to grain-boundary phases of sintered magnet so that thin film of evaporating metal material does not form on surface of sintered magnet.
EFFECT: obtained magnet has high magnetic properties and high corrosion resistance.
