Influence of TiC and TiB2 reinforcement
on the properties and structure
of aluminum alloy AMg2


Yu. V. Sherina, A. R. Luts, A. D. Kachura


The paper presents the results of a study devoted to studying the effect of the type of reinforcing phase on the structure and properties of an aluminum matrix composite material (AMCM) obtained by the method of self-propagating high-temperature synthesis (SHS) in a melt. In the course of the research, an analysis was carried out and a choice was made to use titanium carbide and titanium diboride as reinforcing phases. During the experimental synthesis of SHS in the melt, composite materials AMg2 – 10 % TiC and AMg2 – 10 % TiB2were obtained. In the course of further studies, microstructural, micro-X-ray spectral and X-ray phase analyzes were carried out, according to the results of which it was revealed that the technology used leads to the formation of the target TiC phase in the AMg2 – 10 % TiC composite and TiB2, Al3Ti phases in the AMg2 – 10 % TiB2 composite. On the synthesized samples of composite materials, an assessment was made of physical and mechanical characteristics: hardness, porosity and electrical conductivity. It was found that the hardness of AMCM obtained by the SHS method based on the industrial alloy AMg2 reinforced with titanium carbide is higher than the hardness of AMCM reinforced with titanium diboride by 44 MPa. Also, the porosity of the AMg2 – 10 % TiC composite is lower than that of the AMg2 – 10 % TiB2composite by 6 %. This paper also shows the effect of heat treatment on the physical and mechanical properties of AMg2 – 10 % TiC and AMg2 – 10 % TiB2composite materials. Carrying out additional heating leads to an increase in the hardness values of composite materials, as well as to a decrease in porosity. According to the results of a complex of studies, the use of titanium carbide is recommended as a reinforcing phase.


Keywords: aluminum, titanium carbide, titanium diboride, composite, self-propagating high-temperature synthesis.

Dependence of the density, hardness,
strength and sizes of WC – 15 Co hard alloy
samples on the plasticizer content
in samples got using a 3D printed mold


M. I. Dvornik, E. A. Mikhailenko, A. A. Burkov, D. A. Kolzun


The paper studies influence of the content of the plasticizer (rubber) on the density, microstructure and properties of the WC – 15 Co samples got using a plastic which was made using additive technologies. We have experimentally established that in polylactide molds with strength of 70 MPa, workpieces up to 120 MPa can be pressed. Studies have shown that an increase in the concentration of the plasticizer from 1 % to 4 % leads to an increase in the density of samples from 61 % to 90 % after pressing and a decrease in the density of samples from 99.5 % to 99.3 % after sintering. This is 0.3 – 0.6 % less than the density of samples obtained after pressing in a steel mold at a pressure of 210 MPa. Deviations in density do not affect the microstructure and hardness of the obtained samples, which is 1140 – 1170 HV. Due to the lower density and the presence of individual large pores up to 100 μm in length, the strength of the samples obtained using a plastic mold (1550 – 1980 MPa) turned out to be lower than the strength of the samples obtained using a steel mold (2230 – 2430 MPa). Nevertheless, the density of workpieces and obtained cemented carbide samples turned out to be significantly higher than the density and hardness of samples obtained using existing additive technologies.


Key words: hard alloys, additive technologies, pressing, sintering, hardness.

of glass silica based on waste from the enrichment
of ferruginous quartzite KMA


V. S. Bessmertny, N. M. Zdorenko, M. A. Bondarenko,
A. V. Cherkasov, A. V. Makarov, N. M. Burlakov


Based on the conducted research, it is proposed to use the waste of the enrichment of ferruginous quartzites of KMA as the main raw material for the production of fire-filtered glass silica. The regularities of the formation of the phase composition of glass silica with the formation of such crystalline phases as hematite and hypersthene are established. Based on experimental studies using X–ray phase, differential thermal analysis and IR spectroscopy, a mechanism for the formation of the phase composition of glass silica is proposed. The advantages of the developed technology in comparison with analogues are shown. It was found that after plasma chemical modification, such performance indicators of the front surface of glass silica as water resistance, acid resistance, alkali resistance and hardness significantly increase.


Keywords: Waste from the enrichment of ferruginous quartzite KMA, glass silica, plasmochemical modification, performance indicators.

Formation of hydrophobic coatings
 on the track-etched membrane surface
by magnetron sputtering of polymers in vacuum


L. I. Kravets, V. A. Altynov, R. V. Gainutdinov,
A. B. Gilman, V. Satulu, B. Mitu, G. Dinescu


The surface properties and chemical structure of nanoscale coatings deposited on the poly(ethylene terephthalate) track-etched membranes surface by magnetron sputter deposition of ultra-high molecular weight polyethylene and polytetrafluoroethylene in vacuum are studied. It is shown that the application of coatings leads to hydrophobization of membrane surface, the degree of which depends on the type of polymer used for sputtering and the thickness of the coating. It is established that the use of this modification method leads to smoothing of structural inhomogeneities of the membrane surface layer. This result is explained by the deposition of coatings in the pore channels at a certain depth from the entrance and the overlap of pores on the surface of modified membranes. Besides, the deposition of coatings on the track-etched membrane surface leads to a change in the pore shape. The diameter of the pores on the untreated side of the membranes remains unchanged and decreases significantly on the modified side. The pores of the membranes acquire an asymmetric (conical) shape in this case. The study of the chemical structure of coatings by X-ray photoelectron spectroscopy showed that they contain oxygen-containing functional groups due to the oxidation of the polymer matrix. The developed composite membranes can be used in the membrane distillation processes for the desalination of seawater.


Keywords: poly(ethylene terephthalate) track-etched membranes, magnetron sputter deposition of polymers, polytetrafluoroethylene, ultra-high molecular weight polyethylene, hydrophobization, composite membranes.

The influence of migration of additives
in polypropylene-based films on surface
properties under the action of low-temperature
corona discharge plasma


A. M. Lyakhovich, E. M. Galikhanov, O. A. Bikeev, V. L. Vorobyev


The paper considers the modification of films based on polypropylene containing technological fluorinated additives in corona discharge plasma. X-ray photoelectron spectroscopy and atomic force microscopy were used to study the elemental and chemical composition, relief, adhesive and deformation properties of the film surface before and after plasma modification. It has been established that the modification of a film in a corona discharge plasma leads to the appearance of a technological additive based on fluorine on the surface of the film. In this case, the chemical composition and structure of the film changes, local structures appear on the surface of the film containing atoms of oxygen, fluorine and carbon, which have electrical conductivity different from the electrical conductivity of the surface of the original film. Modification in plasma leads to an increase in the elastic and adhesive properties of the film surface.


Keywords:polypropylene, films, technological additives, corona discharge plasma, migration, chemical composition, structure, adhesion, relief, deformation properties.

Synthesis of complex oxide ceramics
in a fast electron beam


S. А. Ghyngаzоv, I. P. Vasil’ev, V. А. Boltueva


The synthesis of ceramic materials in a fast electrons beam for the production of complex oxide ceramics is considered. Powder reagents, in addition to irradiation, are exposed to air currents that prevent gases and particles from entering the accelerator. To keep powder mixtures of ultrafine powders in the irradiation zone, they were granulated. Two methods of granulation of an ultrafine powder of the composition (in mass %) 80 % Al2O3+ 20 % (ZrO2 – 3 Y2O3) were used. The first method involves moistening, drying and then sifting through a coarse sieve. In the second method, a binding additive was introduced into the powder mixture, which gave the sample a stable volumetric shape. For the granulation methods used, the features of short-term heating of oxide powders in air with a powerful beam of fast electrons with an energy of 2 MeV and the synthesis of zirconia corundum under these conditions were studied. Granulation of the ultrafine powder made it possible to minimize the loss of its mass during irradiation. During irradiation of the powder mass, its local melting took place, which was accompanied by intense gas release processes leading to the formation of hollow ceramic droplets. X-ray phase analysis has shown that mutual dissolution of oxides in their walls does not occur, and recrystallization processes are accompanied by the formation of cubic aluminum oxide microcrystallites and the transition of aluminum oxide in them from the monoclinic to the corundum phase. The presence of microcrystallites of evenly distributed small particles of zirconia dioxide in the interboundary space indicates the production of zirconia corundum under irradiation. At the same time, the phase composition of zirconium dioxide after irradiation does not change in comparison with the initial powder.


Keywords: ultrafine powders, zirconia corundum, granulation, binding additives, synthesis, fast electrons.
