The effect of high-voltage discharge treatment of Fe-20% TiC and VK6-1% ASUD75 diamond powder mixtures on their particle size and morphology is examined. It is shown that high-voltage discharge treatment in a powder suspension permits substantial refinement in the particle size and increase in the shape factor and specific surface area. A near-linear dependence is established between the total treatment energy and powder particle size. It is shown that hydrocarbon liquid is much more efficient than water as a working medium.

The method of the high voltage electric discharge (HVED) treatment in the kerosene (the dispersion, the activation and the synthesis) is proposed to obtain the new anti-friction alloys based on TiC – AlC – and FeC with inclusions of the Cn0 (n=6 or 7) phases which are characterized by the high heat resistance, the strength and the durability to be used in the aircraft and in the rocket technology. The method is distinguished by the hardening particles, which are not mechanically added to the powder mixture, but instead they are synthesized during the HVED treatment of the “kerosene – Fe (Al) – Ti powder mixture” the disperse system with its simultaneous grinding what enable us to create the composite material with the increased mechanical and performance characteristics. The obtained alloys contain the refractory components (the fullerenes, the carbides), the MAX-phases of the Ti-Al-C system as shown by the micro-Raman data.

High voltage electric discharge (HVED) in disperse system “hydrocarbon liquid – powder” due to impact of plasma discharge channel, electromagnetic fields, shock waves mechanical impact, hydro flows and volume microcavitation leads to synthesis of nanocarbon, metal powders dispersion and synthesis of micro- (from 10−6 to 10−7 m) and nanosized (from 10−7 to 10−9 m) composite powders of hardening phases. Spark plasma sintering (SPS) of powder mixtures allows targeted control of grain growth rate and thus allows obtainment of multifunctional composite materials dispersion hardened by nanoparticles. Processes of HVED synthesis of micro- and nanosized powders of new compositions from elemental metal powders and their mixtures with the subsequent application of high-speed SPS of obtained powders create conditions for increase of strength (by 10–20 %), hardness and wear-resistance (by 30–60 %) of obtained materials.
