Problems solved by technology

However, the way to introduce nanoparticles is to colloidally mix nano additives with aluminum alloy spherical powder, then dry, grind and sieve. These processes are relatively complicated and time-consuming, and dispersants NMP, PVP, etc. The carbon and oxygen content in the material increases, which may affect the performance of the printed workpiece

Embodiment 1

[0057] The preparation method of the titanium-aluminum alloy microsphere of the surface nanoporous structure of the present embodiment is as follows:

[0058] (S101) Alkaline solution treatment: 60 grams of spherical TC4 (Ti-6Al-4V) powder with a particle size of 15-53 microns is put into 600 milliliters of sodium hydroxide solution with a concentration of 30 wt %, and a magnet is placed in a magnetic stirrer Continue stirring for 48h;

[0059] (S102) Cleaning: After alkali treatment for 48 hours, stop stirring, let stand for 1 minute, pour out the supernatant solution, add 600 ml of pure water, stir for 1 minute, let stand for 1 minute, then pour out the supernatant solution. Then add a certain amount of pure water, repeat this process for a total of 7 times, and take the solid matter;

[0060] (S103) drying: filter the moisture in the solid matter in step (S102), and dry it in a vacuum oven at 110° C. for 6 hours, and finally take it out after naturally cooling down to norm...

Abstract

The invention discloses a titanium-aluminum alloy microsphere with a uniform nano-porous structure on the surface and a preparation method and application thereof. The method comprises the following steps: (S1) alkali treatment: mixing titanium-aluminum alloy powder with an alkali solution to prepare a mixed solution; and (S2) cleaning: washing the mixed solution in the step (S1) with water, and separating out solids, namely the titanium-aluminum alloy microsphere. The titanium-aluminum alloy microsphere prepared by the method is uniform in surface pores, the pore size is nanoscale, and the pores are only formed in a very shallow layer on the surface of the titanium-aluminum alloy microsphere. The method is simple in process, and the surface pore size and porosity can be adjusted by adjusting the concentration or soaking time of the alkali solution, so that the specific surface area is adjusted.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to a titanium-aluminum alloy microsphere with a uniform surface nanoporous structure and a preparation method and application thereof. Background technique [0002] In recent years, metal additive manufacturing technology has developed rapidly and is used in aviation, aerospace, marine, automotive and medical fields, and can quickly manufacture parts with complex shapes. Since the 3D printing process uses layer-by-layer manufacturing, the performance of the manufactured workpiece is often lower than that of the traditional process. At the same time, since metal powders are melted by electron beams or laser beams during the 3D printing process, the solidification rate is relatively fast, which easily leads to severe cracks, so many metals or alloys cannot be 3D printed. For this reason, many researchers control the solidification rate by adding nano-additive...
