摘　　要：电极感应熔炼气雾化(Electrode induction melting gas atomization,EIGA)是一种制备超洁净无夹杂物金属粉末的先进制粉技术,由于其工艺过程中不使用耐火材料并且所制备粉体具有粒径小、球形度高、无夹杂物等特点,目前已成为大规模制备粉末冶金增材制造用超洁净金属粉末的重要方法。但国内对于EIGA技术引进较晚,对其工艺设计研究还未达到德国等先进国家的水平,因此,本文综述了自1991年德国ALD公司申请专利30年以来EIGA技术的发展及工艺研究现状,对EIGA技术的优点进行了汇总,归纳了EIGA技术的机理研究脉络与技术要点,并通过纵观气雾化制粉的发展历程对EIGA技术的未来发展做了展望,为粉末冶金和增材制造原材料粉末的制备提供了参考。Electrode induction melting gas atomization (EIGA) process is a newly developed method of preparing ultra-clean metal powders. At present, it has become an important method for large-scale preparation of metal powders, especially ultra-clean metal powders for powder metallurgy additive manufacturing. This review introduced the development and process research status of EIGA technology since the patent application of ALD company in 1991, summarized the advantages of EIGA technology, the mechanism and technical points of EIGA technology, and prospected the future development of EIGA technology via the development process of gas atomization, which provides a reference for the preparation of raw material powder for powder metallurgy and additive manufacturing.
