An array of vertically oriented multi-walled carbon nanotubes (VOMWCNT), obtained by chemical vapor deposition (CVD) on a silicon substrate without preliminary catalyst deposition, has been comprehensively investigated. The synthesis was carried out for 30 minutes in the reactor of a carbon nanotube synthesis unit under conditions of decomposition of the reaction mixture (ferrocene in heptane) at a temperature of 800 °C at a carrier gas flow rate of 200 ml/min. The structure and geometric characteristics of the array’s carbon nanotubes were determined using scanning and transmission electron microscopy and Raman spectroscopy. The spectral coefficient of diffuse reflection (SDR) into the hemisphere in the wavelength range from 5,0 to 15,0 μm was determined. From the obtained experimental data, it was found that the emissivity (absorption coefficient) of an array of carbon nanotubes with a height of (230 – 250) μm is 0,98 – 0,99 in the spectral range from 5,0 to 13,7 μm and 0,975 – 0,995 in the range from 13,7 to 15,0 μm. Such a VOMWCNT array can be used to develop an absolutely black body with a high absorption coefficient and small mass and size characteristics, which is used for calibrating spacecraft’s infrared spectrometers.
Keywords:absolutely black body, absorption coefficient, spectral coefficient of diffuse reflection (SDR), infrared radiation range, carbon nanotubes array, spacecraft.

Changes in the structure, phase composition of the hydroxyapatite (HA) plasma coating were established during deposition at an initial 20 °C and 550 °C temperature of the titanium substrate and a spraying distance of 95 and 150 mm. The structure of HA coatings was analyzed by SEM and optical microscopy. DSC analysis established the transition temperatures of HA coatings to the equilibrium state. When deposited on a substrate with an initial temperature of 20 °C at a deposition distance of 95 mm, a nanostructure with a crystallite size of 21 nm is fixed in the HA coating. With an increase in the deposition distance to 150 mm, the non-equilibrium phase composition increases, the crystallite size decreases to 12 nm, the HA content decreases from 72 to 61 %, TTCP from 10 to 5 %, and the α-TCP content increases from 17 to 30 %. A non-equilibrium nano-structural state passes into a more equilibrium state with the release of heat at temperatures of 615 – 727 °C in DSC studies. The high-temperature α-TCP phase is not fixed when the coating is deposited onto a substrate with an initial temperature of 550 °C at a spraying distance of 95 mm, the content of TTCP increases by 2 times, the size of the HA phase crystallites reaches 36 nm and their size in the sprayed powder is 75 nm. The HA coating has a dendritic microstructure and does not have a thermal effect during DSC heating at an initial substrate temperature of 550 °C.
Keywords: hydroxyapatite coatings, atmospheric plasma spraying, heating of a substrate, X-ray diffraction, crystallite size, DSC, SEM.

Modification of the interfacial layer
of reinforced polymer composites
with nanodispersed silicon dioxide
S. A. Koksharov, S. V. Aleeva, N. L. Kornilova,
E. N. Kalinin
The behavior of colloidal silicon dioxide in a composition with a styrene / butyl acrylate oligomer, grafted onto a thermoplastic polyamide adhesive to obtain a branched binder structure with penetration of branches into the capillary-pore system of the reinforcing fiber component, was studied. The variants of disaggregation of SiO2 using ultrasonic treatment and mechanical activation with exposure by high shear stresses, ultrasound and cavitation are compared. Methods of dynamic light scattering, IR spectroscopy, thermal analysis, and textile materials science were used to evaluate the elastic-deformation properties of duplicated packets. The set of complementary results confirms that the combined mechanical activation of an aqueous dispersion of oligoacrylate and silica causes the destruction of silica nanospheres and the formation of a hybrid oligolymer-inorganic adduct. In contrast to the short-term effects of ultrasonic dispersion of SiO2, joint mechanical activation of the components solves the problems of preventing aggregation of nanoparticles and uniform distribution of the reinforcing filler in the composite. The effectiveness of using the method for regulating the properties of forming units and parts of sewing products is shown. When selecting oligoacrylate, specific for sewing production separation of the stages of preliminary bonding of materials using thermoplastic adhesive, the creation of a finished product form and its fixing during wet-heat treatment, is taken into account. The preparation of a hybrid adduct of mechanical activation provides an optimal ratio of particle size for rational distribution of fractions in interfacial, interfiber, and intrafiber spaces of the textile web. The shift of the peaks of phase transitions and chemical transformations in a system with nanodispersed SiO2, controlled on DSC thermograms, is consistent with the temperature regimes of successive stages of the technological process. The possibilities of a controlled change in the properties of forming composite materials and a decrease in the material consumption of sewing products by grafting a modified oligoacrylate with a variable content of silicon dioxide are demonstrated.
Keywords: polymer-fiber composites, nanodispersed silicon dioxide, acrylate dispersion, interaction, mechanical activation, modified hot-melt adhesive materials, elastic-deformation properties.

Effect of carbon nanotubes and oxide nanofibers on mechanical properties of aluminum AD0 after cold working and annealing
A. V. Alekseev, V. V. Strekalov, A. A. Khasin,
M. R. Predtechensky
Cast aluminium composite materials based on AD0 aluminium, reinforced with carbon nanotubes and aluminium oxide nanofibers are obtained. It is shown that the additives of 0.05 wt % of single wall carbon nanotubes (SWCNT) and aluminum oxide nanofibers (AONF) allow increasing ultimate tensile strength of cast metal by 15 % and 16 % respectively. Strengthening of the metal is maintained after cold deformation and annealing. Aluminum AD0 with additives SWCNT or AONF retains high strength after annealing, while aluminum without additives is significantly weakened, this allows to obtain annealed aluminum wire, with a strength limit of 54 – 69 % and yield strength of 53 – 78 % higher than that of metal without additives. The influence of SWCNT and AONF on the size of aluminum grain AD0 in the cast state, after cold deformation and annealing has been studied. Nano-additives have been found to inhibit the growth of metal grains at the stage of collective recrystallization, as well as to influence the process of primary recrystallization of aluminum.
Keywords: aluminum, carbon nanotubes, cast composites, recristallization, microstructure, cold rolling, annealing.

Synthesis of preceramic precursor based
on organic aluminum salts for stereolithographic
3D printing of corundum ceramics

Various options for the synthesis of aluminum acrylates, including substituted hydroxoacrylates, as well as an adduct of aluminum isopropylate with allylamine, have been tested in order to develop a mixture that can be formed by photopolymerization, followed by annealing while maintaining the shape of the ceramics, meaning further molding using stereolithographic 3D printing. By photopolymerization of a polymer precursor based on an acrylate suspension of in situ synthesized alumoxane of the Al(OH)2(ООСН2СН=СН2), corundum ceramics of a given shape were prepared. The inhomogeneity of the polymer precursor is not an obstacle to its use in technology. A significant percentage of weight loss during heat treatment of a polymer precursor suggests its possible use as a binder when filled with dispersed aluminum oxide powder. The strongest shrinkage of a ceramic product occurs in the range of 200 – 400 °C; it is necessary to develop a special program for heating the product to the sintering temperature in order to minimize the consequences of severe shrinkage. When a molded product is heat treated in an inert atmosphere, the shrinkage is less than when annealed in air, since a large amount of amorphous carbon remains during pyrolysis. Annealing such ceramics with amorphous carbon in a nitrogen atmosphere is promising for carrying out the carbonitridization process in the preparation of aluminum nitride and oxynitride.
Keywords:ceramics, aluminum oxide, stereolithographic 3D printing, pre-ceramic precursor, aluminum acrylate, alumoxane.
