| Abstract: | 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. |
| Keywords: | laser cladding coaxial powder feeding nozzle research status situation analysis |
