The possibilities of modification of the structure and type of conductivity of WSe2films formed on p-type silicon by thermal treatment of a thin-film precursor, which was preliminarily created by pulsed laser deposition, are studied. Pulsed laser ablation of WSe2 and rhenium targets made it possible to obtain amorphous films WSex (x > 2) containing rhenium atoms and inclusions of b-W nanoparticles. Heat treatment at 450 °C caused the crystallization of the amorphous matrix and the formation of a layered 2H-WSe2 shell surrounded the metal nanoparticles. Doping with rhenium led to the production of n-type WSe2 semiconductor films, which, in terms of their properties (band gap ~ 1.2 eV, high catalytic activity, low resistance to current transport), represent a promising material for creating p-Si photocathodes for efficient light-activated hydrogen evolution in acid solution. Theoretical calculations are carried out, which make it possible to identify local areas on the surface of the formed WSe2 films with enhanced catalytic activity in hydrogen evolution reaction.
Keywords: tungsten diselenide, conductivity type, photocathode, nanoparticles, rhenium, water splitting, heterojunction.

Study of the mechanical properties
and structure of the “silver – polyethylene
terephthalate” composite
D. V. Panov
Samples of the “silver – polymer” composite were obtained by the matrix synthesis method. Track membranes made of polyethylene terephthalate with pores of different diameters and with different concentrations were used as a matrix. The matrix pores were filled by electrochemical deposition. The structure and mechanical properties of this composite, which is a porous polymer matrix with nano- and microwires of silver deposited into pores, have been studied. Mechanical properties were determined experimentally by stretching the samples. Using the method of scanning electron microscopy, it was found that the length of nano- and microwires filling the pores of the PET matrix is not the same in the same sample, while frequent mutual intersection of the wires was observed, the concentrations of nano- and microwires were determined from SEM microimages. The crossing probability and the number of crossing nano- and microwires were calculated using a previously developed technique based on the single bond method. It is shown that the mechanical properties of the metal-polymer composite are significantly affected by the number of wire intersections and, at the same concentration of wires, their diameter.
Keywords:matrix synthesis, track membranes, electrochemical deposition, nano- and microwires, mechanical properties.

The dependence of the (Zn, Cu, Co, Ni, Mn)-substituted calcium phosphates’ composition on the water synthesis method has been studied. Cation-substituted tricalcium phosphates and hydroxyapatites were obtained by precipitation from an aqueous solution and by the mechanical activation’ method. The reaction products were dried, calcined at 400°C and investigated by ICP AES and flame AAS. The content of Zn, Cu, Co, Ni, Mn in samples and mother liquors was quantitatively determined. It has been established that the content of Cu2+, Zn2+, Co2+, Ni2+ ions in phosphates is greatly reduced compared to the calculated amounts. At the same time, for tricalcium phosphate, precipitation and the mechanical activation’ method gave comparable results for the content of dopant ions. At the same time, the mechanical activation’ method increase the content of the dopant ion in the substituted hydroxyapatites up to ≈ 48 %.
Keywords:calcium phosphates, cationic substitution, ammonia complexes, solution synthesis, AES, flame AAS.

A new microporous carbon material (MUM-51) was obtained from waste coffee grounds by carbonization and activation of KOH. MUM-51 has been characterized by various methods, including N2 adsorption-desorption at 77 K, X-ray diffraction analysis, Fourier transform IR spectroscopy, and Raman spectroscopy. Methane adsorption was studied on the resulting adsorbent at pressures up to 10 MPa and temperatures of 298.15, 303.15, 308.15, 313.15, 318.15, and 323.15 K. The specific pore volume of the adsorbent according to DFT is VDFT = 1.604 cm3/g. The BET specific surface is SBET = 3456 m2/g. The maximum value of methane adsorption at a temperature of 298,15 K and a pressure of 10 MPa reaches ~ 19 mmol/g. Experimental data on methane adsorption on MUM-51 were analyzed using the Dubinin–Radushkevich adsorption model in the temperature range 298.15 – 323.15 K and pressures up to 10 MPa. It has been established that the average relative deviations between the experimental results and the results obtained using the Dubinin-Radushkevich model are less than 3%. The initial differential molar heat of methane adsorption on the MUM-51 adsorbent is 28.7 kJ/mol. The results of the work showed that the carbon material obtained from waste coffee grounds, which has a high specific surface area and porosity, can be effectively used as an adsorbent for greenhouse gases, in particular methane.
Keywords:adsorption, microporous carbon adsorbent, methane, porous structure, adsorption isotherms, heat of adsorption.

Potentiodynamic study of lead
babbit BLa (PbSb15Sn10), with lanthanum,
in the electrolyte environment NaCl

S. K. Sharipov, F. K. Khodzhayev
The results of a corrosion-electrochemical study of the effect of lanthanum additives as an alloying component on the anodic behavior of lead babbit of the BLa brand (PbSb15Sn10), in a NaCl electrolyte medium with a concentration of 0.03; 0.3 and 3.0 % (by weight) are presented. The anodic behavior of babbits was investigated by the potentiostatic method at a potential sweep rate of 2 mV/s. The lanthanum content in lead babbit BLa (PbSb15Sn10) was 0.01, 0.1, 0.50 and 1.0 % (by weight). It was found that with an increase in the concentration of chloride ion in the NaCl electrolyte, there is a shift in the negative region of the values of the potentials of corrosion, pitting formation and repassivation of babbits. The free corrosion potential of lead babbit shifts from time to time to the positive region. Regardless of the composition of babbits, an increase in the rate of their corrosion was established with an increase in the concentration of NaCl in the electrolyte. The addition of lanthanum to lead babbit increases its corrosion resistance. It is shown that lead babbit corrodes by the pitting mechanism and lanthanum as an alloying component of lead babbit BLa (PbSb15Sn10) contributes to the shift of the potentials of pitting formation and repassivation to the region of positive values. This leads to an increase in the resistance of lead babbit to pitting corrosion, and also contributes to the healing of incipient pitting foci.
Keywords:lead babbit BLa (PbSb15Sn10), potentiostatic method, electrochemical behavior, NaCl electrolyte medium, free corrosion potential, corrosion rate.

E. L. Vardanyan, K. N. Ramazanov
The paper presents results of the phase composition investigations of coatings based on the Ti – Al – C system using an X-ray diffractometer and a synchrotron radiation source. A coating based on the Ti – Al – C system was deposited on molybdenum and titanium samples by cathodic-arc deposition from two single-component titanium and aluminum cathodes in a mixture of acetylene and argon. The results of the study of the phase composition showed that the formation of the Ti2AlC and Ti2C phases depends on the heat treatment mode. Using synchrotron radiation, the phase stability of the coating was studied when the sample was heated to 1500 °C in vacuum. It has been established that the coating after deposition has an amorphous structure, which crystallizes after annealing in vacuum with the formation of Ti2AlC, Ti2C phases and Ti – Al intermetallic compounds.
Keywords:plasma treatment, cathodic arc deposition, MAX phase, synchrotron radiation, X-ray diffraction analysis.

Tribological characteristics of structural alloy steels
after laser modification of their surface
S. I. Yaresko, A. T. Kozakov, A. V. Sidashov, V. I. Scherbakov
The microstructure and tribological characteristics of the modified surface of AISI E3310 and AISI A290C1M structural alloy steels after laser treatment using an ytterbium continuous fiber laser have been studied. Laser surface treatment was carried out on air with laser power outputs of 75 W and 100 W and scanning speeds from 2 to 14 mm/s. Metallographic analysis and durometer testing were applied to determine the structure of laser action zones and the steel structural components there. It has been shown that the scanning speed at a laser power of 100 W has the most significant effect on the dimensions of the laser action zones. The maximum depth of the laser action zone during laser treatment without surface melting is 310 and 170 µm for E3310 and A290C1M steel, respectively. Depending on the mode of hardening, the microhardness in the laser action zones varies from 1.36 to 1.97 times for E3310 steel; as for A290C1M steel, it increases by 2.0 – 2.6 times. At 100 µm hardening depth, the reduction in linear wear and wear intensity reaches 26.6 % and 43.9 % for E3310 and A290C1M steel, respectively.
Keywords: laser treatment, structural steels, laser action zone, metallographic analysis, microhardness, tribological testing, wear intensity.
