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,有效的提高了熔覆效果和粉末的利用率。简要的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。
Powder feeding nozzle is used as one of the key components in the powder feeding system which has direct influences on the effect of the laser cladding. With the development of the laser cladding technology, powder feeding nozzle is studied both at home and abroad, so a variety of new powder nozzles are developed to effectively improve the effect of the cladding and powder utilization ratio and reduce the waste. This paper briefly summarizes the domestic and foreign coaxial powder noz- zle progress and powder feeding principle, analyses the existing coaxial powder feeding nozzle status quo, points out the short- comings of the existing powder feed nozzle and proposes that strengthening the powder feed nozzle design is one of the key issues of accelerating the laser cladding development, and then the predicts the future development of the coaxial powder feeding nozzle.
