Abstract
In this paper, a new high precise powder feeder designed for fabricating functionally gradient metal component was presented. The mechanism, control principle and computer control program of the powder feeder were introduced and the powder feeding precise test experiments were carried out with Ni-based alloy powders, Fe-based alloy powders and ceramic powders in the particle average diameter of 15-350 Microns. Experimental results showed that the powders mixtures obtained from the high precise powder feeder are continuous and stable. The precision of delivering powders mixture can be weighed within 2% error scope comparing to the desired mixture quality and the flexible proportion of different powders mixture can be easy changed in the computer control program by synchronously controlling the powder feeder motor’s rotation speed.
