Abstract
The invention provides novel Fe-Co-based wave absorbing micro powder and a preparing method thereof. According to the method, Fe, Co, Al and Er are used as raw materials and are proportioned according to the atomic ratio of Fe10Co7AlxEr2-x (0.5<=x<=1), then smelting is conducted in a vacuum arc furnace, smelted alloy is placed in a vacuum glass tube for homogenizing annealing, then quenching and preliminary smashing are conducted, and finally, ball milling is conducted with a planetary ball mill under the protection of gasoline so that the wave absorbing micro powder can be obtained after the milled product is taken out and dried in the air.
Description
Technical field
The present invention relates to a kind of alloy and inhale ripple micropowder material, particularly a kind of iron cobaltio base alloy adding Al, Er inhales ripple micro mist and preparation method thereof.
Background technology
Along with electronic information technology apply in every field further extensive, bring easily simultaneously to the life of people, also bring serious electromagnetic pollution to society, serious threat is caused to the health of the mankind.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.Metal A l adds in metal, can put forward heavy alloyed ductility, in alloy mechanical milling process, makes micro mist thinner, can improve alloy powder specific area, improves and inhales intensity of wave.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, adjustable FeCo based alloy magnetic conductance, improve absorbing property.The present invention is by mixing Al, Er to reach the suction ripple combination property improving FeCo base alloy.
Summary of the invention
The invention provides a kind of novel Fe-Co base and inhale ripple micro mist and preparation method thereof, this preparation method comprises the steps:
(1) be greater than 99.5% with highly purified metal Fe, Co, Al, Er(purity) prepare burden by certain atomic ratio;
