Scape.Applied metal fibrous composite is also imperative in civilian industry.Metallic fiber is as a kind of emerging fibrous material
It has been subjected to the attention of all trades and professions.
Metallic fiber has been seen varied in appearance.There are stainless steel, carbon steel, cast iron, copper, aluminium, nickel, siderochrome by material point
Aluminium alloy, high temperature alloy etc..It is divided into long fibre, staple fiber, crude fibre, fine fibre, steel wool, heterotypic fibre etc. by shape.
In filter core field, the filter core of fixed particle is particularly filtered, among use, the dust filtered out is easily bonded in
On fiber（Mainly inorfil and organic fiber）, cleaning is inconvenient, the short life that filter core uses.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided a kind of titanium alloy metal for preparing filter core
Fiber, it is characterised in that the titanium alloy material is according to mass percent, including following element：C is 0.04-0.05%, Al
For 1.0-2.0%, V 0.20-0.30%, Mo 2.0-2.5%, Si 0.8-1.2%, Ag 0.1-0.3%, Zr 0.8-
1.2%, surplus is Ti and other impurity.
As an improvement, titanium alloy material includes the P and S that mass fraction is less than 0.024%.
As an improvement, the titanium alloy is by mass percentage, including following alloying element：C is 0.04%, Al 1.7
%, V 0.26%, Mo 2.2%, Si 0.9%, Ag 0.27%, Zr 1.0%, surplus are Ti and other impurity.
The step of preparation of metallic fiber disclosed by the invention, is as follows：
1）Raw material is weighed by component percentages, using the preparation process of existing smelting titanium alloy, is melted in vaccum sensitive stove
Refining casting, obtains the titanium alloy strand for meeting alloying component requirement；
2）Titanium alloy strand is subjected to removing surface, is subsequently placed in vacuum furnace and is heated to 850-870 DEG C, removes alloy casting
The oxide skin on base surface, obtains forging blank, wherein heating rate control is in 120 DEG C/h；
3）Forging blank is continued to be heated to forging temperature to be forged, obtains forge piece；
4）Forge piece is after heat treatment shaped for forming filiform, between a diameter of 1mm-20mm；
5）One layer of uniformly continuous is obtained in wire surface by double glow plasma surface alloying technique oozes ag alloy layer；
6）After the completion of step 5, metal is placed in heat-treatment furnace after carrying out temper；
7）Stretching forms titanium alloy metallic fiber, and the stretching uses the prior art.
In certain embodiments, secondly metallic fiber of the invention can also be directly ejected into cold by material vacuum melting
But system is molded, and the tensile strength of fiber bigger after Overheating Treatment, fiber is more fine and close, among some purposes,
Conductivity higher.
As an improvement, in step 3, forging temperature is 1300-1350 DEG C, and starting forging temperature is 1200 DEG C, stopping forging temperature is
950℃。
As an improvement, after forging blank reaches forging temperature, it will forge blank upsetting pull using forge press and become shape forging
Forging base is formed, wherein, fire time is 3, and forging ratio is controlled in 5.8-6.1；Forging base be cooled to stop forge temperature after, continue to send to oil pressure
Upsetting pull deformation is forged into certain thickness forge piece in quick forging machine, and fire time is 4, and forging ratio is controlled in 1.5-1.8.
As an improvement, in step 4, the temperature of heat treatment is 800-830 DEG C, soaking time 1-2h, then with furnace cooling
But to room temperature.
As an improvement, in steps of 5, the thickness for oozing ag alloy layer is 5-20 μm.
As an improvement, in step 6, temper carries out under vacuum, the temperature of temper is 600-650
DEG C, 2-3h is kept the temperature, is then air-cooled to room temperature.
As an improvement, a diameter of 5-30 μm of titanium alloy metallic fiber.
Embodiment
