Abstract

The invention relates to a preparation method of a magnetic powder composite material. The method comprises the following steps that magnetic molten metal is provided, and the magnetic molten metal drips downwards; a high-speed composite gas is introduced into a dripping path of the magnetic molten metal; and the magnetic powder composite material is collected, wherein the magnetic molten metal isimpacted and crushed by the high-speed atomizing gas to form the magnetic powder composite material. The magnetic powder composite material prepared through the preparation method of the magnetic powder composite material structurally comprises magnetic metal powder and an insulating layer coating film; the magnetic metal powder is made of iron-silicon-aluminum metal material; the insulating layer coating film is made of silicon oxide material; and the surface of the magnetic metal powder is coated with the insulating layer coating film. According to the preparation method, the post-treatmentprocedures, pollution and loss are omitted; and the magnetic metal composite material prepared through the method can be directly pressed into a finished product or prepared into the finished productthrough 3D printing without powder post-treatment.

Description

technical field [0001] The present invention relates to a composite material and a preparation method thereof, in particular to a magnetic powder composite material and a preparation method thereof. Background technique [0002] Metal matrix composites (MMCs) combine the properties of two different materials to improve the shortcomings of traditional single materials by complementing each other's defects. Its properties are determined by the characteristics of the base material and the coating material. In the present invention, the base material is mainly a metal or alloy with magnetic properties, and the coating material plated on the surface is mainly an insulating property. [0003] The magnetic metal composite material described in the field of the present invention is made by powder metallurgy process, and the raw materials mainly include magnetic metal powder and insulating medium. There are evenly distributed gaps between the magnetic metal powders inside the magnet...
