Method of manufacturing magnetic soft material

Abstract

The invention discloses a method for making a soft magnetic material. The magnetic component and the formed metallic glass are melted to form a uniformly melted master alloy block, and then the master alloy block is melted into a liquid state, and Applying a force to it, so that the liquid master alloy bulk material forms a rough powder under the force; after that, sieving the rough powder, and separating a working powder from the rough powder and placing the working powder in a layered manufacturing device to melt the working powder and condense after cooling to form a soft magnetic material. Thereby, the soft magnetic material of the present invention can be formed with a simple manufacturing process, and it has the characteristics of low iron loss rate and better electromagnetic shielding, so that when it is applied to electronic products, it can achieve the effects of improving magnetic permeability and energy saving.

Description

technical field [0001] The invention relates to a method for making a material, in particular to a method for making a soft magnetic material. Background technique [0002] With the advancement of science and technology and the popularization of nano-manufacturing technology, various bulky and fixed electronic products in the past are gradually reduced to portable portable electronic products, and the volume of the components inside the electronic product device is also reduced accordingly. The core material, rotor, stator and other components in existing electronic products are mostly made of silicon steel sheet. Although the silicon steel sheet has the advantages of easy processing and low cost, it also requires a lot of preparation processes due to its characteristics.

Problems solved by technology

The core material, rotor, stator and other components in existing electronic products are mostly made of silicon steel sheet. Although the silicon steel sheet has the advantages of easy processing and low cost, it also requires a lot of preparation processes due to its characteristics. To meet the needs, and the silicon steel sheet has the disadvantages of iron loss and electromagnetic conversion rate deterioration due to the easy rise of temperature during use, so pioneers in this field have successively developed related soft magnetic composite materials to replace it.

However, most soft magnetic composite materials cannot be mass-produced or formed into large-scale or complex shapes due to the limitation of metallic glass forming ability (GFA) and casting technology. High-efficiency soft magnetic materials that are corrosion-resistant and have both soft magnetism, magnetic permeability and magnetic flux properties are actually the goal of many efforts

[0003] It can be seen that the above-mentioned prior art still has many deficiencies, is not a good design, and needs to be improved urgently.
