Abstract
The invention relates to Y-doped rare earth alloy wave absorbing micro powder and a preparing method thereof. The wave absorbing material utilizes Y, Fe and Ni elementary substances as raw materials, the raw materials are prepared and mixed according to an atomic ratio of Y2FexNi<17-x> (X is larger than or equal to 2 and smaller than or equal to 15), and the mixture is smelted into an alloy ingot by a vacuum arc furnace. After homogenizing treatment and quenching treatment are carried out on the alloy ingot, the alloy ingot is mechanically crushed by a grinding tank, and crushed powder is collected and poured in to a ball-milling tank. Under the protection of alcohol filling the ball-milling tank, ball-milling treatment is carried out by a planetary ball mill. After ball-milling is finished, alloy micro powder is taken out and placed on the surface of a powdery iron material, and through natural airing, the alloy wave absorbing micro powder can be obtained.
Description
Technical field
The present invention relates to a kind of alloy inhales ripple micropowder material, more particularly to a kind of alloy absorbing material of addition Rare Earth Y and preparation method thereof.
Background technology
With modern radar and microwave electron technology fast development, absorbing material is set to be used widely in national defence and civil area.Particularly, because mobile communication and electronic equipment are in daily life using more and more extensive, for example apply in the electromagnetic interference of human-body safety protection, microwave dark room abatement apparatus, communication and navigation system, safety information secrecy, improve overall performance, improve signal to noise ratio, electromagnetic compatibility, and many aspects such as waveguide or coaxial absorber element.So that make great efforts to develop having absorbing property good in 1-18 ghz bands, thinner thickness inhales wave frequency bandwidth, and absorbing material with low cost has become one of focus of various countries' investigation of materials.
Absorbing material refers to the energy that the electromagnetic wave on surface can be transformed into greatest extent other forms, to dissipate, decay or electromagnetic wave absorption energy, so as to reach the class functional material for reducing or eliminating reflection of electromagnetic wave purpose.Excellent absorbing material requires there is strong absorption, wideband etc..Traditional absorbing material mainly has ferrite-type and magnetic metal（Alloy）Micropowder etc..Due to ferrite, saturation magnetization is low under 1-18GHz frequency ranges, and microwave magnetic permeability is less, and wave-sucking performance is poor, and matching thickness is thicker（Centimeter Level）, therefore Ferrite Material is subject to great limitation in the application of the frequency range.And lamellar soft magnetic metal micropowder is high due to Curie temperature, temperature stability is good, and lamellar soft magnetic metal micropowder due in surface atomic number it is more and more, the special construction of high concentration crystal boundary and crystal boundary atom causes material under the radiation of electromagnetic field, atom, electron motion aggravation, promote magnetization, electromagnetic energy is set to be heat energy, so as to increased the absorption to electromagnetic wave, there is good application prospect as radio-radar absorber, current magnetically soft alloy micropowder mainly has Fe, Co, Ni and its alloy powder etc..
Rare earth element is because of its special process based prediction model, particularly special electricity, light, magnetic and catalytic performance and be described as the treasure-house of new material, 4f shells are discontented with rare earth atom electron outside nucleus layer, with magnetic moment, 4f shells " buried " are in atom, do not affected by conduction electronics and neighbouring dot matrix to a great extent, the magnetic moment size of rare earth atom or ion not only with atom or iongI is factor-related, also with atom total angular momentumJ It is relevant, these unique properties make rareearth magnetic material produce breakthrough in many fields, such as rare earth permanent magnet, giant magnetostriction material, colossal magnetoresistive materials, magneto-optic and magnetic refrigerating material, rare earth specificity will also affect the mechanism of absorption of electric wave absorbing materials, such as complex permeability and natural resonant frequency, therefore the addition of rare earth and its compound has become the effective way for improving absorber characteristic.Research find by it is a certain amount of it is rare earth doped in iron-based after, the absorbing property of ferrous alloy can be significantly improved.The present invention is added in Fe-Ni based alloys by choosing the rare earth element of certain content, prepares a kind of suction ripple alloy powder of excellent performance.
