The preparation method comprises following steps of adopting metal Fe, Nd and Ti as raw materials according to the certain amount of atomic ratio, utilizing a vacuum arc furnace for melting, carrying out vacuum sealing operation to melted alloy by means of a quartz glass pipe, performing homogenization, quenching and mechanical primary crushing operation to the quartz glass pipe, and utilizing a planetary ball mill to carry out ball-milling under the protection of gasoline. By taking the above steps, an alloy micro-powder wave-absorbing material is obtained.
Description
Technical field
The present invention relates to the preparation method that ripple micro mist inhaled by a kind of alloy, particularly a kind of preparation method adding the neodymium-iron alloy microwave absorbing material of titanium.
Background technology
Along with the development of electronic product, the communication technology, mobile communication, colour TV and refrigerator use widely, and people, while enjoying the Energy and comfort that it brings to the full, also day by day experience its negative effect.Electromagnetic radiation works the mischief to people.Meanwhile, electromagnetic countermeasure and investigation in military affairs, make stealth technique and stealthy equipment development, and electromagnetic wave absorbent material is national governments and the common problem paid close attention to of scientist and society.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, suppresses electromagnetic radiation and interference with this.Now, oneself is stealthy and anti-stealth far beyond military affairs for the application of absorbing material, resist and oppose anti-scope, be more widely used in human-body safety protection, the electromagnetism interference of microwave dark room abatement apparatus and communication and navigation system, security information maintain secrecy, improve overall performance, improve signal to noise ratio, electromagnetic compatibility, and many aspects such as waveguide or coaxial absorber element.How to eliminate Contamination of Electromagnetic Wave, reduce the focus that the harm that brings of electromagenetic wave radiation has become current research.
Microwave absorbing material should have good microwave absorbability and wide absorption band, in addition, also should have little thickness and surface density, good mechanical property and environment resistant performance.Absorbing material has reached tens kinds more than, and wherein applying wider a few class absorbing materials has ferrite, metal fine powder, conduction high polymer and ferroelectric absorbing material etc.In numerous absorbing material, electromagnetic wave absorbing material has clear superiority, and will be main research object, and electromagnetic wave absorbing material mainly comprises ferrite, super-fine metal powder, polycrystalline iron fiber, alloy powder etc.Ferrite has lower dielectric constant, and matching properties is better, but microwave magnetic permeability is not high enough, and the coating of preparation is thicker.And Metal absorption agent has the features such as use good, the saturation magnetization of high-temperature behavior and magnetic loss ability is large, metal fine powder absorbing material is mainly by the attenuation by absorption such as magnetic hystersis loss, eddy-current loss electromagnetic wave.
Because the resource of Fe is abundanter, price is all cheaper relative to Co and Ni, and therefore the preparation of Fe base alloy absorbing material becomes the emphasis of research.FeNd alloy is widely studied with the absorbing property of excellence, although obtain certain achievement, but still there is shortcomings such as inhaling ripple frequency band is narrower, poor stability.Ti is due to its stable chemical property, and good high temperature resistant, low temperature resistant, anti-strong acid, anti-highly basic, and high strength, low-density are " space metal " by good reputation.Add in ferrous alloy, can increase the erosion-resisting ability of alloy, the present invention, by toward alloy doping metals Ti, regulates it mate, the ability of increase alloy corrosion, finally prepares that a kind of absorption band is wide, absorptivity is strong, corrosion resistant microwave absorbing material.
Summary of the invention
