The preparation method of material.
Background technique
W-Cu and Mo-Cu alloy is all the two-phase mixtures tissue group by being neither dissolved and not formed intermetallic compound mutually
At composite material.W-Cu has the characteristics that good resistance to arc erosion, resistance fusion welding, high intensity and high rigidity, extensive
Applied to electric, military equipment, aerospace and other new technical fields, though Mo-Cu can largely realize component
Loss of weight requirement, but its elevated temperature strength and Burning corrosion resistance are still not competent under high-temperature severe environment, can be only applied to some make
With the lower occasion of temperature, such as airvane, counterweight, connecting plate.Therefore, on the basis of W-Cu alloy, with part Mo at
Divide upper substitution W, synthesis W-Mo-Cu composite material is expected to realize the optimum organization of W-Cu, Mo-Cu alloy property, and can be according to need
Change tungsten proportion more neatly to regulate and control to material property, further widens the application range of material, be suitable for
More fields.
It is very few to the research report of W-Mo-Cu composite material both at home and abroad at present, newly retrieved and institute is looked into through technology
The technology related to the present invention recognized only has two.(tungsten seeps the mechanical property of copper product to Tang Liangliang et al. and tissue is ground
Study carefully, powder metallurgy industry, 2011,21 (3): 6-10) it tungsten is prepared using traditional infiltration method seeps copper product, this method is by powder
Granularity be respectively 6.64 μm tungsten powder and 5.0 μm molybdenum powder mix after through cold isostatic compaction, pass through specific heat treatment process
Tungsten skeleton (specific process parameter Wen Zhongwei is provided) is made, metal infiltration of copper is then obtained into tungsten into skeleton in seeping copper furnace
Molybdenum seeps copper product.CN103194629 discloses a kind of preparation method of tungsten molybdenum copper composite material, equally with tungsten mixed-powder pressure
Tungsten biscuit is made, then tungsten skeleton is obtained with the sintering method pre-burning of first vacuum, rear hydrogen atmosphere, then soaks pre-burning skeleton
Enter in liquid phase copper and tungsten molybdenum copper composite material is prepared.Its preparation process are as follows: by tungsten biscuit be placed under vacuum conditions with 10 ~
The heating rate of 30 DEG C/min keeps the temperature 60 ~ 240min after being warming up to 800 ~ 1600 DEG C, is then switched off vacuum, is filled with into heating furnace
Hydrogen, continues 60 ~ 240min of heat preservation, and last furnace cooling obtains tungsten skeleton；Again in 1100 ~ 1400 DEG C of 20 ~ 120min of infiltration
Cooling obtains tungsten molybdenum copper composite material afterwards.This method is not only more demanding to production equipment, and it is high to consume energy；Secondly because need to first obtain
Tungsten skeleton infiltration again is obtained, it need to be by being heat-treated twice, therefore complex process, long preparation period considerably increase production cost；And
Sintering temperature is high, sintering time is long, be easy to cause material grains coarse, influences application of the material as new function material.
To sum up, the method for preparing tungsten molybdenum copper composite material for above-mentioned existing two is infiltration method, i.e., first in high temperature
Under the conditions of prepare tungsten skeleton, then copper is seeped to prepare tungsten molybdenum copper composite material by high temperature.There are sintering temperature height, burning for this method
Knot time length, crystal grain are grown up the disadvantages of serious, and these cumbersome processes increase production process, increase the difficulty of production
Degree increases production cost, to limit the popularization and application of tungsten molybdenum copper composite material to a certain extent.
Summary of the invention
The purpose of the present invention is in view of the above-mentioned problems of the prior art, providing a kind of with the preparation of high current electrical resistance sintering
