摘要:

目前，我國3D打印材料市場規(guī)模已達(dá)到30億元，其中鈦合金占比最大，達(dá)到了20%。3D打印鈦合金零件被廣泛應(yīng)用于航空航天、核工業(yè)、醫(yī)療器械及運(yùn)動(dòng)器材等領(lǐng)域。鈦合金粉末作為3D打印鈦合金零件的重要金屬材料，其性能（包括氧含量、純凈度、球形度、粉末粒徑、粉體密度等）直接影響到3D打印鈦合金零件的成型性能，3D打印鈦粉的制備技術(shù)及工藝已成為國內(nèi)外開發(fā)和研究的熱點(diǎn)。首先詳細(xì)介紹了制備球形鈦粉的主要方法，包括霧化法（氣霧化、離心霧化、等離子霧化）、球化法（激光球化、等離子球化）、造粒燒結(jié)脫氧法，同時(shí)綜述了國內(nèi)外研究現(xiàn)狀；接著對球形鈦粉制備技術(shù)進(jìn)行了比較，認(rèn)為造粒燒結(jié)法因制粉成本低廉而具有很大的發(fā)展前景；最后對球形鈦粉制備技術(shù)的發(fā)展趨勢進(jìn)行了展望。

Abstract:

At present, the market scale of 3D printing materials in China has reached 3 billion RMB, of which titanium alloy accounts for the largest proportion, reaching 20%. 3D printed titanium alloy parts are widely used in aerospace, nuclear industry, medical devices, sports equipment and other fields. Titanium alloy powder is an important metal material for 3D printing titanium alloy parts. Its properties (including oxygen content, purity, spheroidization, powder particle size, powder density, etc.) directly affect the molding performance of 3D printed titanium alloy parts. The preparation technology and process of titanium powder have become a hot spot of development and research at home and abroad. Firstly, the main methods of preparing spherical titanium powder were introduced in detail, including atomization (gas atomization, centrifugal atomization, plasma atomization), spheroidization (laser spheroidization, plasma spheroidization), granulation-sintering-deoxygenation, and the current research status at home and abroad was summarized. Then the preparation technologies were compared, and it is considered that the granulation-sintering-deoxygenation method has a great prospect because of the low cost of powder production. Finally, the preparation technology of spherical titanium powder is prospected.
