【摘要】：高性能球形钛粉具有球形度高、流动性好、松装密度高、氧含量低(0.15%(质量分数))、粒度细等特点,主要应用于金属注射成型、激光增材制造及热喷涂等领域。目前国内外球形金属钛粉的制备技术主要包括雾化法和球化法。雾化法是工业生产制备球形钛粉应用最广泛的方法,主要包括气体雾化、离心雾化、等离子火炬雾化技术以及超声雾化技术,本文详述了各种制备技术的基本原理及其各自特点。其中气雾化技术所制备的钛粉末粒度细小、球形度高、氧含量低,具备大规模生产的能力并且成本低,是目前生产高性能球形钛及合金粉末的主要方法。最后指出低氧低成本细粒度球形钛粉末的制备是钛及合金粉末发展的主要方向,优化制粉工艺、重视粉体基础理论研究是获得高性能球形钛粉的主要途径。
[Abstract]:High performance spherical titanium powder has the characteristics of high sphericity, good fluidity, high loose density, low oxygen content and 0.15% (mass fraction, fine granularity, etc.) it is mainly used in the fields of metal injection molding, laser processing and thermal spraying. At present, the preparation technology of spherical titanium powder at home and abroad mainly includes atomization and spheroidization. Atomization is the most widely used method to produce spherical titanium powder in industrial production. It mainly includes gas atomization, centrifugal atomization, plasma torch atomization and ultrasonic atomization. In this paper, the basic principles of various preparation techniques and their respective characteristics are described in detail. The titanium powder prepared by gas atomization technology has fine particle size, high globality, low oxygen content, large scale production ability and low cost. It is the main method to produce spherical titanium and alloy powder with high performance at present. Finally, it is pointed out that the preparation of low oxygen and low cost spherical titanium powder is the main direction of the development of titanium and alloy powder. The main way to obtain high performance spherical titanium powder is to optimize the powder preparation process and pay attention to the basic theoretical research of the powder.
