原始语种摘要: The high-carbon steel particles obtained by electrospark dispergation of initial granules in ethanol are investigated. The influence of velocity of ethanol laminar flow on particle-size distribution is studied by means of the optical-granulometry method. The tendency towards to decrease of average size of spark-erosion particles is revealed and explained. As shown, the conditions of a particle formation from large fraction have basic influence on particle size, and sizes of particles from small fraction depend on conditions of particles being in dispersion medium. The effect of intermittent increase of small-fraction part under increase of velocity of the working-fluid flow is explained.
