Abstract
In this work, a new laser cladding system on larger area for industrial application has been developed. It consists of wide-band scanning mirror and automatic powder feeder by the rotating feed wheel with bucket-type scoops. It is shown that all kinds of laser cladding powders including not only Ni-base, Fe-base, Co-base, but also superfine and light ceramics powders ZrO2 Al2O3 as well as superfine and heavy WC, TiC with spherical and edged grains can be fed. The powder feed rate can be continuously varied from 0.5 to 200g/min, and the measured tolerance limits are less than 2 percent in all conditions. The powder feeder can deliver powders by both side-band of 10-35mm and focusing band. Without the carrier gas the powder flow depends mainly on gravity. The powder stream at the nozzle is uniform, and the powder utilization factor is over 98 percent. Some applications in metallurgical industry have been successfully made.
