| Abstract Scope |
Tribocharging and particle morphology directly affect the processing parameters and part performance in powder metallurgy processes. Past research has studied the effects of tribocharging and particle morphology on bulk powder flowability; however, the coupled effects of these two factors have not been quantified. This study compares the dependence of flowability on tribocharging and powder morphology through the comparison of two Al 6061 powder morphologies using a rotating drum powder rheometer. To isolate the effects of environmental factors and inherent powder properties, a moisture bakeout treatment was performed and particle size distributions were standardized through sieving. From these experiments, the more spherical Al 6061 powder was found to accumulate charge at a faster rate than the angular powder, with a stronger dependence of flowability on charge accumulation. |
