Amorphous-nanocrystalline modularized stacked sheet, magnetic cell and preparing method of amorphous-nanocrystalline modularized stacked sheet

Abstract

The invention provides an amorphous-nanocrystalline modularized stacked sheet, a magnetic cell and a preparing method of the amorphous-nanocrystalline modularized stacked sheet. The amorphous-nanocrystalline modularized stacked sheet at least comprises m layers of amorphous-nanocrystalline magnetic sheets which are stacked in sequence, and every two adjacent layers of amorphous-nanocrystalline magnetic sheets are connected through a middle glue layer, wherein m is a natural number which is bigger than 1 and smaller than 10; the amorphous-nanocrystalline modularized stacked sheet is suitable for being prepared through the method which comprises the steps of stacking m equal-bandwidth quenched amorphous-nanocrystalline magnetic sheets, rolling the quenched amorphous-nanocrystalline magneticsheets into a ring, spreading the ring after the middle glue layers are formed through crystallization, annealing and glue soaking, then cutting off the quenched amorphous-nanocrystalline magnetic sheets according to the length of the needed magnetic cell, and conducting punching according to the appearance structure of the needed magnetic cell after pressing, flattening and solidification. The amorphous-nanocrystalline modularized stacked sheet has the appearance structure identical to that of the needed magnetic cell, and the large overall magnetic cell can be assembling with n amorphous-nanocrystalline modularized stacked sheets.

Description

technical field [0001] The invention relates to the technical field of amorphous and nanocrystalline magnetic material magnetic components and their preparation, in particular to an amorphous and nanocrystalline modular laminated sheet, a magnetic component and a preparation method thereof. Background technique [0002] In recent years, amorphous nanocrystalline alloys have been favored by people due to their excellent soft magnetic properties such as high saturation magnetic induction, high magnetic permeability, and low loss that traditional silicon steel, permalloy, ferrite and other soft magnetic materials do not have. It is eagerly concerned that the magnetic components processed by it have now partially replaced soft magnetic materials such as traditional silicon steel sheets, permalloys, and ferrites, and have been extremely widely developed and used in the power electronics industry. Due to the wide variety of power electronic products, such as power electronic trans...
