Abstract

The invention discloses a preparation method of a magnetostriction material, and belongs to the technical field of preparation of magnetostriction materials. When a manganese compound is prepared through the preparation method of the magnetostriction material, through a multi-step impurity removal process, the content of iron is reduced, so that the magnetic core loss can be reduced; the preparedmagnetostriction material has a narrow magnetic induction curve, in addition, a glass fiber heat-conducting viscose is utilized for adhering magnetic particles, and the toughness and the strength canbe improved. During sintering, the sintering temperature firstly rises to the higher temperature, and then when the sintering temperature is reduced to the lower temperature, sintering is carried outcontinuously so as to realize densification, so that a magnetic material obtained through sintering can have uniform and fine particles and higher density; ferric oxide is uniformly distributed in themagnetic material, when the magnetic material works under a transformer the high-density magnetic induction curve can be generated, the curie temperature of the magnetic material can be higher, and the saturation flux density is increased, so that the magnetostriction material is improved in magnetostriction performance and wide in application prospect.

Description

technical field [0001] The invention discloses a preparation method of a magnetostrictive material, which belongs to the technical field of magnetostrictive material preparation. Background technique [0002] Magnetostrictive materials are materials with magnetostrictive properties. This feature is used in engineering to convert electrical energy into mechanical energy or convert mechanical energy into electrical energy. Magnetostriction means that under the action of alternating magnetic field, the object produces mechanical vibration with the same frequency as the alternating magnetic field; or on the contrary, under the action of tension and compression force, the internal magnetic flux density of the material changes due to the change of the length of the material. A corresponding change occurs, a current is induced in the coil, and mechanical energy is converted into electrical energy. [0003] Under the action of a magnetic field, the length of the magnetostrictive m...
