Description
Technical field
The present invention relates to a kind of preparation methods of titanium-aluminium alloy, belong to Alloy Processing field.
Background technique
Titanium alloy density is low, and specific strength is high, and creep-resistant property and welding performance are good under corrosion resistance, high temperature, and biology
It is excellent in compatibility, it is widely used in the fields such as aerospace, navigation, chemical industry, power generation, automobile, Leisure Sport, medical treatment.Using molten
Salt electrolysis method produce titanium-aluminium alloy have it is following several:
Using useless titanium Ti6Al4V as soluble anode, carried out in alkali metal oxide salt system Electrowinning (Gao Yupu, Guo Naiming, it is dilute
Have a metal, 1997), be applied alone in time titanium-aluminium alloy powder of method production in addition to aluminum content is very low, it is most important the disadvantage is that: it is different
Granularity aluminum content is different, and particle is smaller, and Han Liangliang is higher, and increases with the anode rate of recovery, and aluminum content increases, and causes in alloyed powder
Aluminum content is unstable, and since aluminium refines crystal grain, causes particle meticulous, and oxygen content is unqualified, is not able to satisfy manufacture structural member
It is required that.
Using the mechanical impurity of give up titanium and aluminium as soluble anode, electrolyte group becomes NaCl-KCl-MgCl2, wherein containing
There is a solvable titanium salt of 1.0-1.5%, carry out Electrowinning titanium-aluminium alloy powder, using the titanium-aluminium alloy powder of this method production department, except containing
Aluminum amount can be made higher outer, equally have the shortcomings that the above items.This is because though titanium, aluminium are mechanical impurities as anode,
Under electrolysis temperature, actually complete alloying generates titanium-aluminium alloy, so unavoidably to generate and use titanium alloy
Identical situation.
Using useless titanium, aluminium as soluble anode, system is electrolysed in the molten salt system for containing solvable titanium salt based on NaCl-KCl
Titanium-aluminium alloy powder is taken, soluble anode is specially separated using titanium, aluminium monometallic.However the method takes titanium, aluminium to refine respectively
Metal powder made from the method for alloy again, alloying is incomplete, using powder as the bad separation of the cathode product of form, easily retains
In fused salt, the folder salt rate of product is high.
Summary of the invention
The object of the present invention is to provide a kind of titanium-aluminium alloys and preparation method thereof.The titanium-aluminium alloy has mechanical property
The advantages of high, thick alloy surface is smooth, is readily cleaned, and impurity content is few, processes convenient for next step.
Technical solution of the present invention: titanium is made as anode by a kind of preparation method of titanium-aluminium alloy, and liquid aluminium is made as yin
Pole is electrolysed in molten-salt electrolysis liquid, titanium-aluminium alloy is prepared.
The preparation method of titanium-aluminium alloy above-mentioned, the molten-salt electrolysis liquid is by main body fused salt NaCl-KCl and soluble titanium salt
Composition.
The preparation method of titanium-aluminium alloy above-mentioned in the main body fused salt NaCl-KCl, is counted, NaCl:KCl in mass ratio
=30~40: 60~80.
The preparation method of titanium-aluminium alloy above-mentioned, the solubility titanium salt is titanate.
The preparation method of titanium-aluminium alloy above-mentioned, the electrolysis temperature are 600~750 DEG C；Faradaic current is 5~10A/
cm3。
Beneficial effects of the present invention: compared with prior art, titanium-aluminium alloy of the invention has the advantage that
The preparation method of titanium-aluminium alloy of the present invention does cathode using liquid aluminium, in the molten state alloying, the titanium aluminium of alloying
Alloy sinks to crucible bottom, is easily isolated, which has that high mechanical properties, thick alloy surface is smooth, is readily cleaned, miscellaneous
The advantages of matter content is few, processes convenient for next step.
