This article discusses the patterns of deagglomeration of aluminum oxyhydroxide nanosheets upon electrohydraulic discharge. The dispersion efficiency by electrohydraulic discharge is higher than that of ultrasound impact. The highest influence on destruction efficiency is exerted by the time of energy release, which determines the intensity of cavi...

The effect of the heating of a Ti substrate to 300 and 550°C on the microhardness of a hydroxyapatite (HA) plasma coating, Ti, and their interface is investigated in specimens in different states (as sprayed, after hydrothermal (650°C, 3 h) and vacuum heat treatment (800, 1000, 1100°C, 3 h)). It is shown that the preliminary heating of the substrat...

To increase the stability of the discharge arc, experimental studies of a plasma generator with a divergent channel of the output electrode are carried out. It is shown that the optimum opening angle of flow of 6° between the inside wall of the channel and the channel axis leads to increased stability of the arc compared to a cylindrical channel of...

Interaction of refractory phase nanoparticles (Al2O3) with a surfactant in Fe–Sn melt resulting in removal of the nanoparticle + Sn complexes to the Me–ceramic or Me–gas interface is investigated. Using the method of atomic emission spectrometry with inductively coupled plasma were developed new methods of quantitative determination of the differen...

The published data on the use of functional composite materials on the basis of Al–Fe intermetallic compounds are presented. Advantages of the solid-phase technology of aluminide production (mechanical alloying + thermal synthesis) when compared to the liquid-phase technology, namely, lower energy consumption and better control over the structure a...

A disperse system of microparticles deposited on the walls of the vacuum chamber at electroarc sputtering of titanium under a nitrogen and acetylene atmosphere is studied by means of small-angle X-ray scattering. It is found that the particles with the radii of gyration Rg ≈ 8–16 nm, which can be classified as mass fractals, i.e., particles (cluste...

The texture formed in the surface layer of a recrystallized VT6 titanium alloy irradiated by highcurrent pulsed electron beams (HEBs) in a melting mode is studied. It was ascertained that irradiation in the melting mode leads to the formation of compression texture and fine globular-lamellar structure in the surface layer with thickness of 20 μm wi...

The X-ray diffraction method is used to study radiation-induced changes in the structure and phase state of a model Fe–5% Mo alloy after electron irradiation at room temperature and 400°C. The observed radiation-induced softening of the alloy is explained by a decrease in the Mo concentration in solid solution and an increase in the number of latti...
