Abstract
1. Способ прессования высокоплотных заготовок и деталей из металлического порошка в присутствии жидкой фазы, включающий введение в порошок жидкости для прессования, отличающийся тем, что в порошок вводят жидкость малой вязкости (например, вода, ацетон) в количестве 10-15% массовой доли. ! 2. Способ по п.1, отличающийся тем, что жидкость вводят в порошок перед прессованием, предварительно перемешивая смесь до получения гомогенной пастообразной структуры. ! 3. Способ по п.1, отличающийся тем, что прессование производят при обеспечении образования в зазоре между пуансоном и матрицей застойной зоны уплотненного материала с созданием эффекта гидравлического затвора. 1. A method of pressing high-density workpieces and parts of metal powder in the presence of a liquid phase, comprising introducing into the powder a liquid for pressing, characterized in that the liquid is injected with a low viscosity (for example, water, acetone) in an amount of 10-15% of the mass fraction. ! 2. The method according to claim 1, characterized in that the liquid is introduced into the powder before pressing, pre-mixing the mixture to obtain a homogeneous pasty structure. ! 3. The method according to claim 1, characterized in that the pressing is carried out while ensuring the formation in the gap between the punch and the matrix of the stagnant zone of the compacted material with the effect of a hydraulic shutter.
