Abstract

The invention discloses a preparation method of a nanometer iron-based soft magnetic block. Nanometer iron-based soft magnetic powder is served as the main raw material. The shape of a nanometer iron-based soft magnetic block to be prepared is designed by professional 3D graphics software on a computer; then, computer graphics processing software decomposes the designed 3D graphics into a series of processing signals controlling laser scanning speed, output power, sintering paths, feeder feeding amount, feeding position and the like by an automatic control device; the feeder and the laser feed and sinter by layers under the control of the signals until the shape of the nanometer iron-based soft magnetic block to be prepared is sintered. The novel nanometer iron-based soft magnetic block is different from the block produced by nanometer ligatures, forms a unified entity, does not have gaps and has favourable permeability; with respect to the known production process of other nanometer soft magnetic blocks, the preparation method has low requirements of environment and technology and does not need to manufacture the corresponding mould in advance.

Description

technical field

[0001] The technology belongs to the field of magnetic functional material processing, and in particular relates to a preparation method of a nanometer iron-based soft magnetic block. Background technique

[0002] Soft magnetic alloy is one of the important functional materials in the electronics production industry. It has superior magnetic permeability than traditional hard magnetic materials, and its power utilization rate is much higher than that of ferromagnetic materials in a wide frequency range, and its volume is smaller. . The application prospects of soft magnetic alloys in aerospace, communications, electric power, electronic technology and other fields are very broad. Soft magnetic alloy raw materials mainly include Mn-Zn series, Ni-Zn series, Cu-Zn series, etc., which are mostly used in transformers, coils, antennas, magnetic heads, switches, etc. In addition, amorphous alloys and alloy films can also be made into soft magnetic materials. With...
