Синтез нанодисперсных порошков карбидов металлов электровзрывным методом с использованием углеродных наноматериалов

Abstract

Processes of synthesis of nanodispersed powders of carbides in the process of electrical explosion of tungsten and molybdenum conductors in the paste containing carbon nanomaterials are experimentally investigated. The paste is obtained by the method of electric discharge treatment of liquid hydrocarbons. It is established that the main factor influencing the dispersed phase and the compositions of the synthesized powders of carbides of tungsten and molybdenum is the ratio of the energy released in a conductor to the energy of conductor’s sublimation. It is shown that the output of carbon-saturated phases and dispersion of carbides increases and the content of residual metal in explosion products decreases with increasing magnitude of input energy.
