“…The filler was formed by high voltage electric discharge (HVED) synthesis. For a high voltage electric discharge synthesis of a filler, there was used a research stand, described in detail in [3]. A mixture of powders of the following initial composition was used as the starting material: Fe (75 %) + Ti (25 %).…”

“…In the process of researches, we varied the distribution of the electric field and plasma formations in the volume of the discharge chamber by using various types of electrode systems (see Table 1 and Fig. 1) [3][4][5]. In this work, we used a 1-point design of the electronic system.…”

“…The use of various electrode systems made it possible to control the distribution of the influence intensity of the main HVED factors [2,3]. So, if in the case of using a 1-point system, most of the accumulated energy is transformed into shock waves, then the use of 15-point systems can increase the intensity of the influence of thermal and current factors.…”

“…Such transformations not only increase the strength and hardness of the filler, but also provide surface activity of the additives to interact with the hydroxyl, carbonyl and epoxy groups of the epoxy resin during crosslinking of CMs. In addition, the authors [3][4][5] have proved that titanium and iron carbides particles are localized on the surface of the particles, and they are mainly the activators of forming physical…”

For the formation of composite materials and protective coatings for the transport industry, ED-20 epoxy yanoic oligomer, the polyethylene polyamine PEPA and microfine fractions of high-voltage synthesized powder charge were used. The dependence of the content of microdispersed powder on the adhesive, physical and mechanical properties, and residual stresses of epoxy composites has been investigated. It has been proved that for the formation of a composite material or protective coating with improved adhesive and cohesive properties, the optimal particle content is 0.05–0.50 parts by weight per 100 parts by weight of the ED-20 epoxy oligomer. Such materials are characterized by increased mechanical strength and the ability to resist static and dynamic loads, since their properties are significantly increased compared with the matrix. The obtained results of experimental studies of physical and mechanical properties of composite materials are consistent with the test results of samples with adhesive characteristics, indicating their reliability.

“…The details of this electric discharge technique were described in ref. [19] Electric discharge in liquid is essentially an electric explosion involving the release of energy in the discharge channel within microseconds. High energy density in the channel results in shock waves, which are transformed into a wide range of acoustic waves of wide spectrum of frequencies accompanied by powerful hydrostreams, cavitation, and by thermal and electromagnetic fields.…”

Fe, Ti powders, and their mixtures were subjected to electric discharges in a hydrocarbon liquid. During this treatment, the powder particles' refinement and carbide phase formation occurred. The obtained powder mixtures were consolidated by spark plasma sintering at 900°C for 5 min under uniaxial pressure of 50-60 MPa. The densification behavior, microstructure, phase composition, and mechanical properties of the processed powder samples were investigated. The obtained results indicate the final structure sensitivity to the powder chemical composition and to the regimes of the powder synthesis by the electric discharges. The developed fabrication approach represents a novel technological route for metal-ceramic powder composites' fabrication where the electromagnetic field assistance is employed at both powder synthesis and powder consolidation stages.
