Abstract

The methods of compacting dry polydisperse and nanometric powders into required shapes with improved density distribution have been developed: pressing under powerful ultrasonic action and collector pressing by the control of friction forces redistribution. Modeling and experimental investigation of the deformation process of a powder body by different methods show that in the case of ultrasonic pressing, the relative differential of density along the pressing height has decreased by 35% as compared to the conventional uniaxial pressing. Collector pressing promotes decreasing dispersion of density distribution by 10 times, and reducing the relative density differential along the sample height by 60%.
