Description
The present invention relates to a kind of preparation method of Ti-Al alloy powder, particularly a kind of fused salt electrolysis prepares the method for Ti-Al alloy powder.
Adopt molten salt electrolysis for producing Ti-Al alloy powder existing following several:
1, is soluble anode with useless Ti-6Al-4V, in alkali metal chloride salt system, carries out electrolysis and produce [Gao Yupu, Guo Naiming, rare metal, 1979.4, P21, В. and Г. Г о п и e н к о, А. И. И в а н о в, Н. И. А н у ф р и e в а; Э л e к т р о л и т и г e с к о e р а ф и н и-р о в а н и e т и т а н а в р а с п л а в л e н н ы х с р e д а х, М. М e т а л л у р г и я, 1972, c.96], but in the Ti-Al alloy powder of producing with this method except that aluminum content is very low, topmost shortcoming is, different grain size aluminum content difference, and particle is littler, aluminum content is higher, and increase with the anode rate of recovery, aluminum content increases, and causes aluminum content instability in the alloy powder, again because the aluminium crystal grain thinning, cause particle meticulous, oxygen level is defective, can not satisfy the requirement of manufacturing structure spare.
2, with the mechanical mixture of useless titanium and aluminium as soluble anode, ionogen consists of NaCl-KCl-MgCl
2, wherein contain 1.0～1.5% solvable titanium salts, carry out electrolysis produce the titanium aluminum alloy powder [Ю. Г. О л e с о в, Г. А. М ee р с о н, В. С .y с т и н о в; ц в e т н ы e М e т а л л ы 1970, № 5, c.79], the titanium aluminum alloy powder that adopts this method to produce, except that aluminum content can do higher, have above every shortcoming equally.Though this be since titanium, aluminium be mechanical mixture as anode, under electrolysis temperature, alloying has generated titanium aluminum alloy in fact fully, so unavoidably will produce and use the identical situation of titanium alloy.
In addition, the molten salt system that aforesaid method adopted is formed and is difficult to still also guarantee that the aluminum content in the powdered alloy product obtains stable control.Purpose of the present invention:
Purpose of the present invention just provides the novel method that the titanium aluminum alloy powder is produced in a kind of fused salt electrolysis, and this law is avoided the shortcoming of original technological method, and it is stable to make aluminum content, the alloying constituent may command, and oxygen level is qualified, can use the titanium aluminum alloy powder for powder metallurgy.
The present invention is that a kind of employing is a soluble anode with useless titanium, aluminium, at NaCl-KCl is that main body contains in the molten salt system of solvable titanium salt electrolysis and produces the Ti-Al alloy powder method, its principal feature is that the present invention adopts titanium, aluminium monometallic to separate soluble anode, promptly with useless titanium, aluminium separately separately as soluble anode, be that main body contains in the molten salt system of solvable titanium salt electrolysis and produces Ti-Al alloy powder with NaCl-KCl.
Aluminum anode weight of the present invention is 5～50% of titanium anode weight, the metal ratio that makes in the alloy and the metal ratio in the anode is complementary, with the corresponding Ti-Al alloy powder of making aluminum content 1%～40%.The useless titanium of titanium anodic can be titanium sponge or titanium bits, and the aluminium of aluminum anode can be secondary aluminium.At NaCl-KCl is that solvable titanium salt contained in the fused salt of main body is TiCl
n(wherein 2≤n≤3), added TiCl
nBe 0.5%～8% of fused salt gross weight, add minor N aAlCl simultaneously
4Constitute NaCl-KCl-TiCl with NaF
n-NaAlCl
4-NaF molten salt system, its add-on account for 0.15%～6% and 0.5%～15% of fused salt gross weight respectively.In molten salt system, also can add as AlCl
3, KAlCl
4, KF
3Replace NaAlCl Deng the compound that contains aluminum ion, fluorion
4And NaF.
The anodic current density that is adopted during electrolysis of the present invention is 0.1A/cm
2～1.2A/cm
2, cathode current density is 0.3A/cm
2～5A/cm
2, electrolysis temperature can adopt 750 ℃～900 ℃, every excellent electrolysis time is 1～4 hour, the negative electrode product is with 1%～2% salt pickling, spend dried up cleaning again after, in vacuum drying oven, dry.
The present invention has adopted titanium, aluminium monometallic to separate soluble anode, because titanium aluminium is separated, anode can not form alloy in electrolytic process, this has just been avoided in original technology with titanium, aluminium mixture and Ti-6Al-4V is that soluble anode carries out a series of shortcomings that electrolysis brings, reduced the effect of aluminium crystal grain thinning, can make in the alloy powder aluminum content almost irrelevant with granularity.Again owing in fused salt, added aluminum ion and fluorion, make in the alloy aluminum content stable, and be easy to control, and aluminum content does not increase with the anode rate of recovery and changes in the alloy.Thus, it is qualified to make oxygen level, recovery rate reaches more than 80%, can be for medium size (28 orders～180 orders) Ti-Al alloy powder and the titanium aluminium mother alloy powder of powder metallurgy use, and this will be significant for the cost and their application of expansion that reduce titanium alloy product significantly.
Specifically describe the present invention below in conjunction with accompanying drawing:
Accompanying drawing prepares the electrolyzer synoptic diagram of titanium aluminum alloy powder for fused salt electrolysis process of the present invention.
In the accompanying drawing of electrolysis unit; electrolytic cell (1) generally can be made by the charcoal steel; put into the metal trough (3) of containing aluminium block (2) at bottom land; the iron net (5) of containing useless titanium (4) is placed on the metal trough (3); titanium, aluminium are separated; aluminium block (2) and useless titanium (4) namely are the anodes of separating; in electrolytic process, can not form alloy; in electrolytic cell, add fused salt (6); negative electrode (7) can move up and down by insulation movable sealing (8); electrolytic cell is found time from bleeding point (9), is full of argon shield from air-filled pore (10) again. Owing to adopt the anode of this form, just avoided a series of shortcomings of bringing in original technology. Reduce the effect of aluminium crystal grain thinning, made in the alloy aluminum content almost irrelevant with granularity, can make that to separate out in the alloy aluminum content stable, can produce again the higher medium size alloyed powder of aluminum content.
