摘　　要：送粉喷嘴作为送粉系统的关键部件之一,直接影响着激光熔覆的效果。随着激光熔覆技术的发展,国内外对送粉喷嘴进行了深入研究,研制出了多种新型送粉喷嘴,都有效地提高了熔覆效果和粉末的利用率。简要概括了国内外对于同轴送粉喷嘴的研究进展以及送粉原理,分析了现有同轴送粉喷嘴现状,指出了现有送粉喷嘴存在的不足,提出加强送粉喷嘴的设计是加速送粉激光熔覆发展的关键问题之一,并对同轴送粉喷嘴的前景进行了展望。The effect of laser cladding is directly influenced by powder feeding nozzle which is one of the key components in powder feeding system. With the development of laser cladding technology, powder feeding nozzle is researched domestically and abroad deeply. New powder feeding nozzles are developed and cladding effect as well as powder utilization coefficient is improved effectively. The research progress and powder feeding principles of domestic and foreign coaxial powder feeding nozzle are summarized briefly. The situation of existing coaxial powder feeding nozzle is analyzed and the shortcomings are pointed out. One of the key issues for developing the powder feeding laser cladding is to improve the design of powder feeding nozzle. And the future development of coaxial powder feeding nozzle is forecasted.
