Methods of the research comprise a physical experiment in the laboratory; diagnostics of SHS processes; the analysis of the synthesis products. The analytical expressions are obtained to calculate the electrical parameters providing SHS discharge-pulse initiation. Laboratory test beds for implementation and study of SHS processes are manufactured. Exothermic systems for the synthesis of carbon and metal-carbon nanomaterials are chosen. The conditions of discharge-pulse initiation of SHS processes are experimentally investigated: the power for SHS ignition by discharge current pulses per unit area of the sample surface is from 0.1 to 1 MJ/(m2.s), the density of the prepared powder mixtures in which the ignition of SHS occurs are ranging from 700 to 1,900 kg/m3. The conditions of formation and regularities of SHS is such powder systems as aluminium + EPDM, aluminium + EPDM + iron, aluminum + composite F4К20, titanium + graphite, titanium + carbon nanomaterials are experimentally investigated. We determined due to experiments the main parameters of the SHS process of these powder systems: ignition temperature; linear burn rate; width of the heating zone; wavelength and speed of heating the substance in a wave. The results of the x-ray phase analysis showed that most of the initial powders came into the SHS reaction with formation of carbon nanomaterials or carbides.5481 Product Description popup.authors Баклар В.Ю.
