摘要： The bonded magnet of the present invention, in which average particle diameter and compounding ratio are specified, is comprised of Cobalt-less R1 d-HDDR coarse magnet powder that has been surface coated with surfactant, R2 fine magnet powder that has been surface coated with surfactant (R1 and R2 are rare-earth metals), and a resin which is a binder. The resin, a ferromagnetic buffer in which R2 fine magnet powder is uniformly dispersed, envelops the outside of the Cobalt-less R1 d-HDDR coarse magnet powder.

摘要： Compression molding suitable anisotropic magnet powder had not been established facing the difficulty of contradiction of high density and magnet powder alignment. By applying both magnetic field and pressure at the moment when the resin is melted into liquid state by heating, both high density and a high degree of magnet powder alignment are attained. Furthermore, application of degassing and ultrasonic vibration were found to be effective. An anisotropic bonded magnet with the maximum energy of more than 20 MGOe, in other words, more than 80% of the theoretical value of maximum energy product, is obtained.

摘要： In HDDR (hydrogenation, disproportionation, desorption and recombination) treatment, a mass production method and its apparatus for anisotropic rare earth magnet powder had not been established because it is difficult to keep a constant temperature of material due to an exothermic/endothermic reaction with hydrogen. The present invention compensates for the heat accompanied with the exothermic/endothermic reaction by a counter reaction by the use of dummy material. The apparatus includes sets of a processing vessel and a heat compensating vessel in contact and in control of their temperature. The apparatus enables the temperature control of HDDR treatment within a desired range and constantly brings out the maximum property from the material. The controlability of the method is independent of the production scale so that mass production by HDDR treatment can be set into practice.

摘要： A production method for a case-integrated bonded magnet includes: filling a tubular cavity with a magnet raw material that includes a rare-earth magnet powder and a thermosetting resin binder; heating the magnet raw material to cause the thermosetting resin softened or melted while compressively molding the magnet raw material to obtain a tubular compact; discharging the tubular compact from the tubular cavity while press-fitting the tubular compact into a metal tubular case having an inner peripheral surface coaxial with the tubular cavity; and heat-curing the tubular compact with the tubular case to cure the thermosetting resin. The tubular compact press-fitted into the tubular case is thermally cured thereby causing the tubular compact to transform to a tubular bonded magnet, which expands unexpectedly due to heat.
