Problems solved by technology

However, in addition to high initial permeability, high permeability materials should also have high quality factor, high relaxation frequency, etc., and today's iron-nickel alloys often pursue high permeability at the same time. Ignoring this part of the requirements, it is impossible to take into account other parameters while improving the magnetic permeability, so that the material properties can reach a good balance

Abstract

The invention discloses a preparation method of a composite amorphous magnetically soft alloy material. The composite amorphous magnetically soft alloy material comprises components of Fe67Co18Si11B4-Ni71P29. The preparation method comprises the following steps: firstly, an amorphous magnetically soft alloy thin strip is prepared; then, chemical nickel-phosphorus plating liquid is prepared; and the composite amorphous magnetically soft alloy is prepared by a chemical deposition method. The composite amorphous magnetically soft alloy material has the following advantages: the composite amorphous magnetically soft alloy prepared through the chemical deposition method is excellent in performance; the initial permeability can be increased by one order of magnitude under the conditions of frequency of 1 kHz-1 MHz and alternating magnetic field of 0.05 A / m, and is basically invariable by being kept at 1870; and the relaxation frequency and the quality factor are obviously improved compared with a traditional alloy. The composite amorphous magnetically soft alloy is simple in process, convenient to operate, low in cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of magnetic functional soft magnetic materials and chemical deposition of nickel phosphorus, in particular to a composite amorphous soft magnetic alloy material and a preparation method thereof. Background technique [0002] Soft magnetic materials refer to those metal magnetic materials with low coercive force and high magnetic permeability, which have important and extensive applications in electricity, electronics and modern new technologies. With the rapid development of digital communication technology and optical fiber communication, traditional analog communication equipment is constantly updated and eliminated; most of the various power transformers used in the communication field work at low magnetic flux density, and the magnetic permeability of the material starts at this time. played a major role. Especially with the development of high-frequency technology, higher requirements are put forward for the hig...
