Abstract
The invention provides an iron-cobalt based alloy microwave absorbing material and a manufacturing method thereof, wherein the method comprises: high purity metals of Fe, Co, Y and Al are used as raw materials; the materials are matched by certain atom proportion and the material is smelted by utilizing a vacuum electric-arc furnace; the smelted alloy is put into a vacuum glass pipe to perform annealing processing evenly, quench processing, preliminary pulverizing processing and finally ball-milling processing by utilizing a planet-type ball milling machine under the protection of gasoline; and the alloy is taken out, thus an alloy micro powder wave absorbing material is acquired.
Description
Technical field
The present invention relates to a kind of preparation method of alloy microwave absorbing material, particularly a kind of preparation method of iron cobaltio base alloy microwave absorbing material.
Background technology
Along with modern science and technology fast development, it is further extensive that various electronic information technology is applied in every field, while bringing great convenience, also brings serious electromagnetic pollution to society, cause serious threat to the health of the mankind to the life of people.Microwave absorbing material as a kind of can the functional material of electromagnetic wave absorption, electromagnetic wave energy can be converted into other forms of energy by it, electromagnetic radiation and interference is suppressed with this, there is good effect, therefore countries in the world all fall over each other to drop into a large amount of manpowers and material resources to research and develop high performance absorbing material, become one of focus.
Traditional absorbing material mainly contains ferrite-type and magnetic metal (alloy) micro mist etc.Because ferrite saturation magnetization under 1-18GHz frequency range is low, microwave magnetic permeability is less, and wave-sucking performance is poor, and matching thickness thicker (Centimeter Level), and therefore Ferrite Material is subject to great limitation in the application of this frequency range.And sheet soft magnetic metal micro mist due to Curie temperature high, temperature stability is good, there are larger saturation magnetization and grain shape effect, higher complex permeability and lower eddy-current loss can be obtained under 1-18GHz frequency range simultaneously, matching thickness less (grade), has good application prospect as radio-radar absorber.Current magnetically soft alloy micro mist mainly contains Fe, Co, Ni and alloy powder etc. thereof.
FeCo base soft magnetic materials has higher saturation magnetization, magnetic conductivity, lower coercivity and small loss and other features, therefore be widely used in fields such as Aeronautics and Astronautics, navigation, military and civilians, also cause the great interest of scientific research personnel simultaneously, have lot of documents to report the performance being improved FeCo base soft magnetic materials by development new component in the world every year.The performances such as special optical, electrical, the magnetic that rare earth element has because of the particularity of its structure that other elements many do not have, are described as " treasure-house " of new material.Metal A l adds in metal, can put forward heavy alloyed ductility, in alloy mechanical milling process, makes micro mist thinner, explores further the absorbing property improving FeCo base alloy, and the present invention is by mixing rare earth element y and Al reaches the absorbing property improving FeCo base alloy.
