Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Metal 3D printing technology has far-reaching development potential. It can not only form metal parts with complex structures, but also has more flexibility and high performance for applied materials. It can change the composition of traditional raw materials to obtain better performance. Component. In this field, the powder-spreading laser 3D printing technology needs to use fine powder of about 0-53 microns as raw material, and nano-ceramic particles can be used for material enhancement technology, and the addition method of nano-ceramic particles is the core of...

Abstract

The invention provides a system and method for preparing nano-ceramic-reinforced titanium alloy powder. The method comprises the steps that high-pressure argon gas carrying nano-ceramic powder is collected into injection holes of an annular gas delivery pipe through an argon gas atomization passageway and is sprayed downwardly, a gas curtain carrying the nano ceramic powder is formed and is continuously collected to the position of the top of a cone, the gas curtain carrying the nano ceramic powder collides with liquid dropped from a titanium alloy rod, the titanium alloy liquid drops at the position of the top of the cone are scattered, and spherical titanium alloy fine powder is formed; and meanwhile, the nano ceramic powder uniformly dispersed in high-pressure gas is driven into the spherical titanium alloy fine powder and is uniformly dispersed in the spherical titanium alloy fine powder formed after scattering, and finally the spherical titanium alloy fine powder with the nano ceramic powder uniformly distributed is formed. The system has the beneficial effects that the reinforced titanium alloy powder with the nano ceramic particles deeply dispersed into the titanium alloy powder body can be prepared, the yield of the fine powder is high, and therefore the requirements of the special fields are met.

Description

technical field [0001] The invention belongs to the technical field of high-activity metal powder preparation, and in particular relates to a preparation system and method of nano-ceramic reinforced titanium alloy powder. Background technique [0002] Titanium is widely distributed in the world, and its content exceeds 0.4% of the mass of the earth's crust. The global proven reserves are about 3.4 billion tons, and its content ranks 10th among all elements. The order of the top 10 elements is: oxygen, silicon, aluminum , iron, calcium, sodium, potassium, magnesium, hydrogen, titanium. Titanium is 40% less dense than steel, yet its strength is comparable to steel, which increases structural efficiency. At the same time, titanium has good heat resistance, corrosion resistance, elasticity, elastic resistance and formability. Titanium alloys have been used in the aviation industry since their appearance. The Space Shuttle is a major aircraft with a wide range of applications....
