Purpose of the research is to develop new discharge pulse methods of synthesizing nanodisperse powders of metal carbides. Methods of the research comprise physical experiment, electronic microscopy methods, X-ray diffraction analysis and X-ray spectrum microanalysis. It is shown that oscillating fading mode at U0 = 35 kV and C = 0.1 µF is efficient for synthesizing metal carbides by electrodischarge treatment of cyclohexane with use of aluminum, columbic, titanium, and molybdenum electrodes. It is established that the key factor acting on phase and disperse composition of synthesized nanosize carbide powders is the ratio of stored energy to metal sublimation energy, and the degree of carbon atoms hybridization in molecules of pastes does not affect the product characteristics. The most efficient mode of carbide synthesis is definitely the electric explosion of conductors with diameter of 0.3 mm and length 50 mm with repeated current bursting without pauses when the stored energy exceeds the sublimation energy more than 3 times. Recommendations are prepared for producing discharge pulse technology of synthesizing metal carbide nanopowders. Product Description popup.authors Терехов А.Ю. popup.nrat_date 2020-04-02 Close
