The Design of Powder Feeding System for Laser Remanufacturing
The stability of powder feeding is important to guarantee the quality of the laser remanufacturing. In order to detect and control the powder flow, a new powder feeding device is designed for laser remanufacturing. Scraper-type conveyer and capacitance sensor are used into the device which is tested by 2Cr13 and H13 powder. The results show that: Using H13 metal powder as medium will get a better effect，and when the changes of powder density are more than 10-1g/min, the device acts better distinguish-ability. The experimental results demonstrate that the system can be used to control the steel base powder feeding.
