摘要
处于制粉技术前沿的超声振动雾化技术以其在粉体质量、形貌与粒度分布等方面的独特优势而逐渐成为高品质、高性能金属与合金粉末的重要制备手段。概述了超声雾化制备球性微细金属粉末的技术特点,阐述了金属超声雾化技术的原理与相关机制,总结了近年来超声雾化在机制、粒度控制和工艺改进等方面的研究进展,同时介绍了国内外新近发展起来的复合型高效超声雾化技术和最新研究热点,以及针对实现窄粒度分布、扩大雾化金属种类方面所采取的相应对策。
Ultrasonic atomization has become an important method of advanced metallic powder manufacturing for its best powder quality. The process characteristics, basic principle and mechanism of ultrasonic atomization technology for the production of spherical metal powder were summarized in briefly, then the design principle, materials selection and acoustic impedance matching inquiring of power ultrasonic atomizer were discussed. novel ultrasonic Besides above atomization equip topics arousing people＇s interests introduced comprehensively. In ways to reduce the range of and extend were presen applicable field ted. mentioned, several ments and research around world were the meantime, the particle size of ultrasonic distribution atomization
