Abstract

The invention discloses a cold deformation structure adjustment nano composite permanent magnet conductive contact and a manufacturing method thereof. The permanent magnet conductive contact is composed of three parts: a fixed sleeve, a core body and a coil; the core body is an alloy which is finally obtained by taking 6-8 parts by weight of neodymium, 3.5-4.5 parts by weight of molybdenum, 0.05-110 parts by weight of ferroboron FeB22C and 5-7 parts by weight of yttrium as raw materials, mixing, carrying out cold pressing deformation adjustment for multiple times and annealing; the composite core body is obtained by taking pure copper as a shell, and the composite core body is sleeved in the fixed sleeve; the coil is formed by winding an aniline modified carbon fiber aluminum core composite wire wound on the surface of the core body, and the coil is wound on the inner surface of the fixed sleeve. The Curie temperature is high, the thermal stability is good, and corrosion resistance andoxidation resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of electrical devices, in particular to a cold-deformed structure-adjusted nanocomposite permanent-magnet conductive contact and a manufacturing method thereof. Background technique [0002] Because the magnetic energy product research of Nd-Fe-B single-phase permanent magnet materials has reached the bottleneck, and its shortcomings such as low Curie temperature, thermal stability, corrosion resistance and oxidation resistance are still difficult to overcome. The preparation of a new generation of Sm2Fe17Nx single-phase permanent magnet materials has not made breakthrough progress so far due to the uncontrollable composition, phase composition and distribution. Therefore, the development of composite materials has become the focus of researchers. Theoretical research shows that the two-phase nanocomposite permanent magnet material has the high saturation magnetization of the soft magnetic phase and the high...
