The polyaniline (PANI) films filled by carbon particles can demonstrate the conductivity increasing. The carbon particles uniform distribution in the PANI films can be received by their contemporaneously formation in the atmospheric pressure plasma. The films properties produced from aniline contemporaneously with carbon particles in the atmospheric pressure plasma are considered in that paper. The energy density threshold (~ 30 mJ/m) of gas discharge starting from which it is possible to obtain a continuous film filled with agglomerates of carbon particles was defined. It was showing that the such films has the amorphous morphology. It was defined that the carbon particles agglomerates in the PANI films. The carbon particles agglomerates concentration in the PANI films is about ~(4 – 7)·104 1/cm2 and slowly depends on the energy density. So the conductivity of that films cant be increasing by this particles. It was shown that the films moisture saturation is the main reason of them conductivity increasing. It was shown that the films creep are decreases and the hardness increases when the gas discharge energy density increases. Its because the crosslinks number is growth in the samples. The molecular weight of PANI films is low, so the Martens hardness value has low-level.

The experiments results on the ablation of high-carbon (> 97 % Fe, 1.3 % C) and low-carbon (> 97 % Fe, 0.3 % C) steel targets by a nanosecond pulse laser radiation scanning beam are presented. The dependence of the depth and energy efficiency of ablation on the power density in the range q = 4·108 – 1010 W/cm2 has been determined. It has been established that the maximum efficiency of material removal is achieved at q = 4·109 W/cm2 for a high-carbon steel target and in the range q = 7·108 – 5·109 W/cm2 for a low-carbon steel target. The size distribution of ejected microparticles was determined. It has been established that a back flow of particles occurs upon irradiation of high-carbon steel and the flow origin mechanism is associated with nanosized condensate particles. Based on the reflectivity measurements and the electron microscopy microstructure study of the irradiated surface, it has been suggested that the mechanism for the higher efficiency of ablation of high-carbon steel compared to low-carbon steel is the condensation process of supersaturated carbon vapors on the target surface that increases the irradiated target surface absorptivity and, consequently, the material removal efficiency of the subsequent scanning pass is increased.

The internal friction method was used to study the behavior of the Zr – 1 wt. % Nb alloy after oxidation in air, nitriding in an atmosphere of technical nitrogen, and in situ carburization during measurements. In this case, carbon was deposited on the samples during measurements due to thermal decomposition of vapors of diffusion oil. The pressure in the system was about 10–2 Pa. The temperature dependence of the logarithmic decrement of damped bending vibrations with a frequency of 2.2 – 2.4 Hz was measured on specimens in the form of a rectangular plate 22 × 8 × 0.3 mm in size. The measurements were carried out at a constant heating rate of about 4 K/min from room temperature to 700 – 750 °C. The obtained temperature dependences of internal friction were divided into partial maxima using a special program. The program determines the temperatures of the relaxation maxima and calculates the effective activation energy using the Werth — Marx formula. The internal friction spectra in successive measurements on one sample changed due to the diffusion redistribution of the alloy components. The parameters of the relaxation maxima for carbon (153 – 159 kJ/mol), oxygen (203 – 207 kJ/mol) and nitrogen (235 – 238 kJ/mol) in the alloy under study, depending on the experimental conditions, have been established. Grain-boundary (Gb) impurity maxima due to these impurities were also found. The following activation energies were obtained: 173 – 179 kJ/mol for C-Gb, 216 – 219 kJ/mol for O-Gb and 222 – 229 kJ/mol for N-Gb. Impurity grain-boundary maxima associated with carbon, oxygen, and nitrogen were observed in each series of measurements. The activation energy of the grain-boundary maxima proper decreases monotonically from 202.4 to 194.5 kJ/mol in a series with oxidation in air (experiments 711 – 715), and remains about 200 kJ/mol in nitrided samples.

Four plasma cermet coatings with similar compositions based on TiC carbide and NiCrMo matrices with additional Cr3C2, WC carbides, and carbon were studied. The average oxygen content for four cermets increases from 0.51 % for powders to 0.86 % for coatings with a minimum plasma power and does not increase with its increase. The maximum average nitrogen content in the coatings, 0.34 %, is determined by the nitrogen content in the plasma. When spraying coatings, the loss of carbon, relative to the initial powder composition, is 2.79 – 3.76 %, less than in the manufacture of powders for spraying 4.3 – 6.6 %. Carbides Cr3C2, WC, matrix elements and the content of additional carbon determine the formation of the annular zone around TiC carbide, increase the total carbide content in the coating from 60 to 74 – 83% and the microhardness of the coating is 18 GPa with an indenter load of 200 gf.

The process of crystallization of LTA type zeolite promising for practical use has been studied, the influence of various factors on the rate and selectivity of synthesis using natural minerals from Nakhchivan has been considered. The influence of temperature in the range of 80 – 150 °C, the weight ratio of the initial components of halloysite (G) and obsidian (O) G:O, equal to 1:1, 1:2, 1:3, 2:1 and 3:1, the concentration of the used thermal NaOH solution in the range of 5 – 30 % and the process duration in the range of 10 – 100 hours for the crystallization of LTA were studied. It has been determined that the optimal conditions for the synthesis of a single-phase zeolite of the LTA type with 100 % crystallinity are: temperature 100 ± 10 °C, concentration of thermal NaOH solution — 10 – 15 %, the ratio of the initial components of halloysite (G) and obsidian (O) G:O, equal to 1:1, processing time — 20 hours. Synthesis of zeolite LTA using natural minerals of Nakhchivan was carried out in the presence of tetramethylammonium hydroxide (TMAOH). The effect of temperature, concentration of thermal NaOH solution, ratio of initial components, duration of aging on the process of LTA crystallization has been studied. It was shown that violation of the optimal synthesis conditions leads to a decrease in the selectivity of the process and the formation of other zeolites (X), aluminosilicates (sodalite, anorthite, sanidine) or their associations, as well as quartz. The process of aging was studied in the duration interval from 1 to 3 days. It has been determined that an increase in the aging duration leads to an increase in the linear rate of crystallization of the LTA zeolite.
