Common titanium alloy, especially γ bases TiAl intermetallic compound are above because with high specific strength, high specific stiffness, anti-corrosion, resistance to
The advantages of mill, high temperature resistant and excellent antioxygenic property, as fields such as contemporary aerospace industry, civilian industries
One of good candidates structural material, particularly has broad application prospects in blade of aviation engine field.Current aviation hair
Motivation blade is generally casting or forging method shaping, and 3D printing, or increasing material manufacturing are quick as one kind of rising in recent years
Moulding process, using successively powdering, laser or electron beam melt the mode being molded, and realize the finishing shaping of precise part,
And the defects such as the shrinkage cavity shrinkage porosity of casting process appearance are avoided, as a kind of emerging material manufacturing process.For 3D printing
For, the parameter such as purity, granularity of powder directly affects the material property after shaping, thus the preparation method and powder of research powder
The performance of material has great importance.But not yet find to prepare the 3D of TiAl-base alloy workpiece and correlation using 3D printing at present
The report of printing TiAl intermetallic compound powder, preparation method thereof used.
The content of the invention
In order to solve the above technical problems, the invention provides preparation method of the 3D printing with TiAl intermetallic compound powder,
By the way of chemical reduction method secondary reduction, the recovery rate of powder is improved, and improves the uniformity of powder particles.
The complete technical scheme of the present invention includes：
The preparation method of a kind of 3D printing TiAl intermetallic compound powder, it is characterised in that comprise the following steps：
1) titanium salt solution that selection concentration is 0.1-0.13mol/L, and 0.1-0.13mol/L aluminum salt solution are mixed, plus
Enter ultrasonic wave under cationic surfactant mixed liquor, heating condition to stir；
2) ammoniacal liquor regulation pH value is added；
3) the first reducing agent, the lower heating response of ultrasonic wave stirring are added；
4) reaction solution is centrifuged, sediment washing is dried to obtain first group of TiAl intermetallic compound powder product；
5) the second reducing agent, the lower heating response of ultrasonic wave stirring will after the supernatant concentration after centrifugation, be added；
6) reaction solution is centrifuged, sediment washing is dried to obtain second group of TiAl intermetallic compound powder product.
It is preferred that, first reducing agent and the second reducing agent reducing power are different.
It is preferred that, cationic surfactant be volume ratio be chlorination benzalkonium, lauryl dimethyl benzyl ammonium chloride,
C15The mixture of trimethylammonium bromide.
It is preferred that, step 2) in ammoniacal liquor regulation pH value be 5-9.
It is preferred that, reducing agent adds the 1/4-1/6 that volume is mixeding liquid volume.
It is preferred that, step 1) in heating-up temperature be 40-60 DEG C.
It is preferred that, step 5) in heating-up temperature be 120-160 DEG C.
The present invention is relative to the advantage of prior art：Traditionally, the processing side that powder metallurgy etc. is molded using powder
Powder used in method includes two kinds of alloyed powder and element powder, and carries out institute in forming method using TiAl intermetallic compound powder at present
Powder is typically to select the Ti alloyed powders and Al alloyed powders that meet proportioning to be reprocessed after being mixed in processing, process not
It is evitable to there is uneven, the problems such as deviation occurs in local component of mixing, and the present invention uses chemical combination reducing process, directly makes
Standby to go out to meet the TiAl intermetallic compound powder of component requirements, powder component is uniform, and printing effect is improved during 3D printing
Fruit and component capabilities, while designing chemical reduction method preparation technology prepared by suitable TiAl intermetallic compound powder, are obtained
Powder Particle Size is uniform, while secondary reduction method, and by the way of the different reducing agent of reducing power, it is to avoid the grain of first reduction
Footpath is big, the problem of easily reunite, while improving the recovery rate of powder.
