[0030] Preparation method of magnetostrictive material

[0031] The present invention uses direct-write molding equipment to implement the preparation method of the present invention. The direct writing molding equipment used in the present invention, for example, can be composed of a molding system and an air pump system located on a three-dimensional motion platform. Among them, the molding system uses a moldless molding platform to prepare three-dimensional structures. The slurry is stored in a syringe, which can move in three-dimensional space, and the two parts are controlled by a microcomputer. When working, the slurry in the syringe is extruded by the high-purity nitrogen gas to push the piston out of the needle, and accumulates on the base in a line shape. According to the diameter of the needle, it can be processed into strips of different diameters. The needle cylinder can move along the x direction and the y direction. After completing a two-dimensional structure,...

[0063] Preparation of Magnetostrictive Materials

[0064] In the illustrated embodiment, the moldless forming platform used is an air-bearing three-dimensional motion platform produced by Aerotech Corporation of the United States. The precision of its own mechanical movement can reach 400nm, which can meet the precision requirements of three-dimensional movement.

[0065] The air pump system adopts the air pump EFD U1traTM 2400 manufactured by A Nordson Company to provide the power to push the piston during molding, and its output air pressure range: 0~689.5kPa. The volume of the syringe used in this example is 30ml, φ22.5mm; the inner diameter of the needle is 0.5mm, and the corresponding working air pressure is controlled between 480~580kPa. on a ceramic substrate.

[0066] The pre-designed 3D model is provided by Fe 3 o 4 A 10mm×10mm woodpile structure made of slurry. The woodpile structure has 8 layers, and the distance between adjacent lines on the same layer is 1mm. ...

Abstract

The invention discloses a preparation method for magnetostrictive material and the magnetostrictive material. The preparation method for the magnetostrictive material includes that providing raw material nanometer powder slurry; extruding the slurry, accumulating in linear shape to form a pre-designed three-dimensional model to obtain a sample blank; drying and sintering the sample blank to obtain the cured magnetostrictive material. The preparation method for the magnetostrictive material realizes to manufacture the magnetostrictive material through a three-dimensional mold-less slurry direct-write forming technique, the technique is simple and controlled through program, and different slurry and structure models can be prepared according to needs; the preparation method for the magnetostrictive material manufactures the magnetostrictive material with the complex grid structure in one time, and accordingly the production cost is lowered, the agility is improved, and the magnetostrictive characteristic is greatly improved.

Description

technical field [0001] The invention relates to the technical field of preparation of magnetic functional materials, in particular to a preparation method of a magnetostrictive material and the magnetostrictive material. Background technique [0002] Ceramic three-dimensional moldless slurry direct writing molding technology is a moldless direct writing molding method that does not rely on molds and does not require subsequent external processing to prepare micro-scale three-dimensional complex structural functional ceramic materials. This technology uses air pressure as the power to extrude the raw materials, and the designed structure is obtained by controlling the molding equipment layer by layer through the computer program. It is a method integrating computer-aided design, precision machinery and material science. The processing of polymers, functional ceramics and some soft materials (such as paraffin), especially in the preparation of functional ceramic devices, has t...
