Problems solved by technology

Magnets are used in various environments. For example, in actual use, magnets often need to be used in high-temperature environments, but the high-temperature resistance of magnets in the prior art is poor, and high temperatures often cause magnets to demagnetize, resulting in magnets that cannot be used normally. Severely shortens the service life of the magnet

Abstract

The invention relates to the technical field of magnet manufacturing, in particular to a production process for infiltrating graphene into a magnetic body. The production process for infiltrating graphene into a magnetic body comprises the following steps of: providing a magnetic body; the magnetic body is made of magnetic material; Providing a heating device for heating the magnetic body; Providing graphene powder, wherein the graphene powder is composed of nanometer graphene particles; Providing a spraying device for spraying and infiltrating graphene powder into a heated magnetic body of the heating device; By infiltrating graphene powder into the magnetic body, the high-temperature resistance of the magnetic body is improved, so that the magnets formed after magnetization of the magnetic body have high-temperature resistance, demagnetization caused by the decrease of the coercivity of the magnets due to the high use ambient temperature of the magnets or the high ambient temperatureduring assembly is avoided, and the service life of the magnets is prolonged.

Description

technical field [0001] The invention relates to the technical field of magnet manufacturing, and in particular discloses a production process of graphene infiltrated into a magnetic body. Background technique [0002] Magnets are one of the basic components commonly used. In the manufacturing process of magnets, first use magnetic materials (such as metal materials containing iron, cobalt or nickel, etc.) to make magnets, and then magnetize the magnets to make the magnets into a magnet. Magnets are used in a variety of environments. For example, in actual use, magnets often need to be used in high-temperature environments, but the high-temperature resistance of magnets in the prior art is poor, and high temperatures often cause magnets to demagnetize, resulting in magnets that cannot be used normally. Seriously shorten the service life of the magnet. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of ...
