摘要
钛合金因其具有高的比强度、比刚度和良好的耐腐蚀性能,广泛应用于航空航天、汽车以及增材制造等领域。球形钛合金粉末是增材制造的核心原料,对3D打印产品的质量起着关键作用。目前增材制造用钛合金粉末的主要制备方法包括电极感应熔炼气雾化法(EIGA)、等离子旋转电极雾化法(PREP)和氢化脱氢—等离子球化联合法(HDH-PS)等,介绍这些制备方法的原理及研究现状,探究钛合金球形粉末制备技术的影响因素,进而展望增材制造用钛合金粉末技术未来的发展方向。
Due to the high specific strength,specific stiffness and high corrosion resistance,titanium alloys are widely used in aerospace,automotive,additive manufacturing and other fields.Spherical titanium alloy powder is the core raw material of additive manufacturing,which plays a key role in the quality of 3D printing products.At present,the main preparation methods of titanium alloy powder for additive manufacturing include electrode induction melting gas atomization(EIGA),plasma rotating electrode process(PREP)and the combined method of hydrogenation-dehydrogenation and powder spheroidization(HDH-PS)etc.The principles and research status of these preparation methods are summarized in the study.The influencing factors of the preparation technologies are also explored.Finally,the paper gives a prediction of the future development direction of titanium alloy powder technology for additive manufacturing.
