Description
Technical field
The present invention relates to the preparation method of a kind of titanium of the micro- hydrogenation in surface or titanium alloy powder, belongs to field of material preparation.
Background technology
Gas atomization is that one kind is directly smashed by high velocity air and quickly cooling molten metal prepares metal dust
Method, it applies extremely wide, is used in particular in the production of 3D printing metal dust.3D printing is referred to mathematical model
It is foundation, the technology of 3D solid object manufacture is carried out by way of material successively adds up, represents world's development of manufacturing
New direction.The metal objects prepared using 3D printing technique in order to ensure the consistency and uniformity of its internal organizational structure,
To be respectively provided with high requirement using the size distribution of metal dust, sphericity and mobility, oxygen content etc..
Titanium alloy has a series of excellent properties such as light weight, high-strength and anti-corrosion because of it, be widely used in Aero-Space and
The fields such as military project, are also that metal 3D printing field uses a most class materials.Aerosolization rule is to prepare 3D printing to be closed with titanium
The common method at bronze end, a kind of fine grain hypoxemia spherical titanium and titanium alloy that such as Chinese invention patent CN104308168B is announced
The preparation method of powder.However, due to the high chemism of titanium elements, easily reacting in titanium alloy powder table with oxygen
Face generates fine and close oxide layer, and the presence of titanium oxide substantially increases the laser sintered difficulty of titanium alloy powder, and then affects
The Forming Quality of 3D printing part.To prevent the oxidation of titanium alloy powder, Chinese invention patent CN103846447B from disclosing one kind
The aerosolization preparation method of superfine spherical titanium or titanium alloy powder, the method is carried out using double-deck atomizer to titanium or titanium alloy
Atomization and hydrogenation, have the titanium of hydrogenation titanium film or the preparation of titanium alloy powder so as to complete Surface Creation.But the method is in system
There are some weak points in powder practice：First, using double-deck atomizing nozzle structure so that atomizing nozzle structure is complicated, manufacture
It is relatively costly；Secondly, the introducing position that air-flow is hydrogenated in the method is too near apart with atomization air flow, melts and is formed after body fluid flow atomization
Melt drop still there is higher temperature, and titanium or titanium alloy hydrogenation rate at high temperature is very high, causes powder easily excessive
Hydrogen is inhaled, powder hydrogenation process is difficult to control to；Again, because hydrogenation air-flow is introduced from atomizer, whole atomization cavity is caused
Inside there is hydrogen, on the one hand, the still titanium with the higher temperature or titanium alloy powder long-time in atomization cavity connects with hydrogen
Touch, cause powder excessively to inhale hydrogen, and the titantium hydride of a large amount of brittlement phases is internally generated in powder, affect powder quality, on the other hand,
Hydrogen is not only filled with whole atomization cavity, meanwhile, hydrogen can also diffuse into working chamber by the mozzle of atomizer, give
Powder production brings larger potential safety hazard；Finally, the hydrogen of titanium or titanium alloy powder excessive consumption is laser sintered in 3D printing
During concentration release, not only affect the Forming Quality of 3D printing part, and be discharged into and print hydrogen excessive in bin and also will
Form certain potential safety hazard.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of that above prior art is present, there is provided a kind of titanium or titanium of the micro- hydrogenation in surface is closed
The preparation method at bronze end, had both solved double-deck atomizer and had inhaled the uncontrollable problem of hydrogen process, and the safety of manufacture is improve again
Property.
To realize object above, the technical scheme is that：A kind of titanium of the micro- hydrogenation in surface or the system of titanium alloy powder
Preparation Method, with titanium or titanium alloy rod bar as raw material, is protected by forvacuum with high purity inert gas are passed through, and prevents titanium or titanium from closing
Oxidation of the gold in fusing with atomization process, and titanium or the fusing of titanium alloy bar one end and shape are made by the way of induction coil heating
Into stable liquid stream, the liquid stream carries out powder by atomization by the atomizer using high purity inert gas as medium again, atomization
Stress control is in 3～8MPa；The titanium or titanium alloy powder that atomization is completed is carried along into cyclone separator by air-flow, in whirlwind point
The high-purity hydrogen of 0.3～0.5MPa, 10～25at.% of hydrogen content and the mixed gas of high purity inert gas are passed through from device lower end, and
The suction hydrogen on its surface is completed using powder itself residual temperature, on powder surface very thin suction hydrogen layer is formed, realize that titanium or titanium are closed
Micro- hydrogenation on bronze end surface.
Further, forvacuum is to vacuum 1 × 10-4～1 × 10-2Pa。
Further, high purity inert gas are using high-purity argon gas or high-purity helium.
Further, the thickness for inhaling hydrogen layer is 30～100nm.
Compared with prior art, the invention has the beneficial effects as follows：
(1) due to substantially reducing into the titanium of cyclone separator or the temperature of titanium alloy powder, now, the suction hydrogen of powder
Speed is greatly reduced, and so as to only form very thin suction hydrogen layer on powder surface, has not both served the effect of micro- hydrogenation oxygen barrier, and not
Powder over-hydrogenation can be made；
(2) low pressure hydrogen for introducing from cyclone separator cavity lower end and the height from atomization cavity into cyclone separator
Pressure atomization gas go in the same direction, because its pressure is significantly less than atomization gas, thus can only be in cyclone separator one
Fraction region forms hydrogenating environment, without in atomization cavity, its security is greatly improved.
(3) titanium or titanium alloy powder of the micro- hydrogenation in surface prepared by the present invention, pollution less, mobility and non-oxidizability
It is good, it is especially suitable for 3D printing and uses.
