Abstract

The invention discloses a preparation method of a magnetostrictive material, which belongs to the technical field of magnetostrictive material preparation. When the present invention prepares the manganese compound, through the multi-step impurity removal process, the content of iron can be reduced, which can reduce the loss of the magnetic core. The prepared magnetostrictive material has a narrow magnetic induction curve. In addition, the magnetic particles are bonded with glass fiber heat-conducting viscose, And can improve its toughness and strength; when sintering in the present invention, the sintering temperature is first raised to a higher temperature, and then when the sintering temperature is lowered to a lower temperature, the sintering is continued to achieve densification, and the magnetic material obtained by sintering can be With more uniform and fine particles and higher density, the iron oxide is evenly distributed in the magnetic material. Using the magnetic material to work under the transformer can produce a high-density magnetic induction curve, which can make the Curie temperature of the magnetic material higher. , increase the saturation magnetic flux density, so that the stretching performance of the magnetostrictive material is improved, and the application prospect is broad.

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...
