Abstract
The invention relates to a magnetic alloy powder material which adopts FeCOMSiBTi as the base material and comprises the following components by atomic percent contents: 20-25 cobalt, 3.5-4.5 M, 8-12 silicon, 10-15 boron, 1-3 titanium, and residual Ferrum and small amount of inevitable impurities, wherein the M can be combined with one or more of niobium, molybdenum, vanadium and zirconium.
Description
Technical field
The invention belongs to field of functional materials, refer to especially a kind of magnetic alloy material powder production method.
Background technology
In the prior art, magnetic material particularly magnetic material is used as producing the product that high frequency transformer, magnetic head etc. need to utilize magnetic material properties.Magnetic material refers to compare the magnetic material with demagnetization performance with permanent magnetic material.The now production of main magnetic material prepares with Ferrite Material substantially, and the key property of this class Ferrite Material is the advantages such as resistivity is high, and the high-frequency vortex loss is little.But the saturation induction density of the magnetic product of this material preparation is on the low side, temperature characterisitic is poor, only can be used in the scope that temperature is lower than 100 ℃, when temperature surpasses this scope, its performance sharply descends even magnetic disappears, so this class material is not suitable for the application under the hot conditions.
China's patent 20041002990 provides a kind of FeCOMSiB of employing alloy material and has improved the consumption of Co element.Although this technical scheme can have higher temperature characterisitic, contain Co high magnetic alloy storage magnetic property and demagnetization speed not high, CO belongs to narrow resources with respect to China simultaneously, and the import dependency degree surpasses more than 90%, therefore is necessary prior art is improved.
In the metal smelt process, pass through melting, cooling, the processes such as reprocessing, complex procedures, and in each operation, all need to consume the generation that a large amount of energy also has pernicious gas, now there has been technology to adopt alloy powder die casting mode to produce alloy product, like this can
Summary of the invention
The objective of the invention is by improvements over the prior art, also can improve the demagnetization performance of this class magnetic material at the temperature characterisitic that guarantees magnetic material and storage magnetic property.
The present invention is achieved by the following technical solutions:
Magnetic alloy powder material, described magnetic alloy material are the FeCOMSiBTi base material, and each composition forms and comprising by atomic percentage conc (at%): the cobalt of 20-25,3.5-4.5 M, the silicon of 8-12, the boron of 10-15, the titanium of 1-3, all the other are iron and a small amount of inevitably impurity; Described M is one or more combination in copper and niobium, molybdenum, vanadium, the zirconium.
The atomic percentage conc of described copper (at%) is 0.8-1.2; The atomic percentage conc of one or more combination (at%) is 2.7-3.3 in described niobium, molybdenum, vanadium, the zirconium.
Further improve, described M is the combination of copper and vanadium.
The invention has the beneficial effects as follows:
Compare with prior art, this magnetic material alloy has preferably hot properties and storage magnetic property, is for the preferred magnetic material of making magnetic head.
Further improve, described M is the combination of copper and vanadium.
