Аннотация

Two methods of compacting dry poly- and nanodisperse powders into compacts of a complicated shape with uniform density distribution in the volume have been developed: pressing under powerful ultrasonic action and collector pressing by the control of friction forces redistribution. Experimental measuring and simulation of the process of deformation of a powder body by different methods show that in the case of ultrasonic pressing, the dispersion of the density distribution has decreased by 20%, and the relative differential of density along the pressing height has decreased by 35% as compared to the case of the conventional uniaxial pressing. Collector pressing allows reducing the dispersion of the density distribution (has decreased by a factor of 10), while the relative density differential along the green compact height has decreased by 60%.
