Description
Technical field
The present invention relates to magnetic material, especially relate to a kind of preparation method of soft magnetic alloy compound material with high magnetic conductivity.
Background technology
Continuous development along with the telecommunications industry, telecommunications device such as mobile phone, popularizing of notebook computer etc., electromagnetic interference is increasing to the influence that environment causes, the annual economic loss that causes because of electromagnetic pollution is up to 500,000,000 dollars, and the anti-electromagnetic interference material of microwave in the development ghz band scope has caused that people more and more pay attention to, simultaneously, microwave absorbing material is the basic material of develop high-tech military project, is the key point of stealth technology.No matter be civilian or military, the anti-electromagnetic interference material of microwave all had higher requirement that higher absorption efficiency and higher by frequency is the anti-electromagnetic interference Development of Materials of a microwave direction.
The saturation magnetization of metal soft magnetic material is more much bigger than ferrite, but because its conductivity is bigger, forms eddy current easily, worsens its performance.Thereby, just can develop and the anti-electromagnetic interference performance good metal of high frequency soft magnetic material if can find a formation that suppresses inner closure domain to reduce the eddy current loss of material.The research of this respect is beginning very early, be to use the alternate laminated construction of magnetic thin film and thin dielectric film the earliest, because the thickness of film is less than the skin depth of material, thereby effectively suppressed the formation of eddy current and closure domain, but this kind laminated construction can cause the formation of direct capacitance, form displacement current, the high frequency magnetic permeability that is unfavorable for material, the analysis showed that, the electrostatic capacitance that this magnetic metal/dielectric alternate laminated structure produces, depend on the size of magnetic metal body length direction, if this alternate laminated structure is divided into column structure, electrostatic capacitance then can be suppressed to insignificant degree.This column alternate laminated structure metallicl magnetic material has good magnetic characteristic under high frequency, but because the restriction of its cost, manufacture craft etc. is difficult to be suitable for the application of anti-electromagnetic interference material.Under the inspiration of this thinking, if magnetic thin film part with this alternate laminated structure kind, the flat powder that to use thickness instead be about skin depth and have big aspect ratio, flat powder uses polymer to isolate, can constitute cheap for manufacturing cost, and can realize producing in batches, and high frequency performance is similar to the anti-EMI material of alternative stacked column structure.Use the anti-electromagnetic interference material of this kind method preparation, cost is low, and technology is simple, can realize large-scale industrial production.
The Fe-Si-Al metal soft magnetic material is a kind of traditional soft magnetic material, though its comprehensive soft magnet performance is less than nano-crystal soft-magnetic series, but the composite material that Fe-Si-Al micro mist after the researcher of Japan handles flattening and organic insulating material are mixed and made into similar magnetic thin film/thin dielectric film alternating structure, find that it has good anti-emi characteristics in the quasi-microwave section, injected new vitality for again this traditional metal soft magnetic material.Simultaneously because this material does not contain strategic elements such as cobalt, nickel, particularly when approaching celestial Da Site (Sendust) alloy of its composition, have and the same magnetic permeability high under low-intensity magnetic field of perm (Perm) alloy, and saturation magnetization (M
s) higher, resistivity is bigger, be more suitable for using under high frequency, so its application in anti-electromagnetic interference field more and more is subjected to people's attention.
It is that the resistivity of metal soft magnetic alloy is low that metallicl magnetic material has individual common drawback as anti-electromagnetic interference material, and used thickness reduces material thickness and can enlarge its range of application at high frequency, but also be subjected to certain limitation owing to be subjected to the restriction of skin depth.The skin depth of metal soft magnetic alloy square with its resistivity proportional, so improving resistivity is one of method that effectively improves its magnetic permeability, the Ti element can improve the resistivity of Fe-Si-Al alloy, in the Fe-Si-Al alloy, add Ti, adopt the fast melt-quenching technology and change ball-milling technology and heat treatment temperature, obtain the nano-crystalline Fe SiAlTi alloy of high magnetic permeability, the flat powder of alloy and the mixing processing and preparing of binding agent are got sheeting have high magnetic permeability.
