Adsorption of harmful organic pollutants on the example of the standard dye-methyl orange - onto the nanostructured material — mesoporous carbon — is considered. The physical and chemical properties of the sorbent were determined. The experimental kinetic results were studied using the pseudo-first- and pseudo-second-order, external and internal diffusion, and the Elovich models. The equilibrium sorption data were described with the Langmuir, Freundlich and Temkin models. The kinetic studies showed that the time for reaching equilibrium is 10 min. The maximum adsorption capacity of the material used was found to be 827.5 mg/g. From the adsorption kinetic studies, it was elucidated that the extraction of the dye molecules takes place in a mixed diffusion mode and in accordance with the pseudo-second-order model. Along with the “sorbate – sorbate” chemical interaction, the correspondence between the experimental data and the Elovich model indicates chemical heterogeneity of the sorbent surface. The equilibrium adsorption data were well correlated in the coordinate planes of the Freindlich and Temkin models, thereby standing for multimolecular sorption and different chemical activity of the adsorption sites. Besides, the basic adsorption rate constants were also calculated.

Keywords: mesoporous carbon, adsorption, organic contaminates, dyes, kinetic, equilibrium.

The end buried light edge-emitting diodes (LED) with wide emission spectrum in the wavelength range of 1380 – 1420 nm were made. The construction of the linear end LED with the channel in a substrate and with an active region and a crescent-blocking layers of InP/GaInAsP/p-n-p-n/ZnSe was shown. There was held the LED dock with an optical single-mode fiber and a microlens on the end of an optical fiber. The characteristics of the LEDs based on the mesa stripe heterostructures InP/GaInAsP were investigated. The dependence of the output power and LED emission spectrum on the basis of the mesa-stripe heterostructure InP-InGaAsP-InP active region with crescent and p-n-p-n/ZnSe structure, blocking the leakage current, the temperature stabilization of the active element and the injection current were studied. The dependence of the output parameters from the emitter temperature stabilization, which enables the creation on the basis of LED devices as the data with positive or without forced cooling was demonstrated. The possibility of creating of buried LEDs with crescent active region and a low degree of modulation of the radiation spectrum was shown. The possibility of entry to 45% of the radiation of LEDs in a single mode optical fiber with a microlens produced by chemical etching and the spliced fiber end in a high arc welding machine was demonstrated.

Radiation properties of the metal structural materials
during low-temperature damaging irradiation

V. M. Chernov

The state of structure, defects (mobility) and physical-mechanical properties (elastic moduli, strength, plasticity, brittle fracture, cold brittleness) of the metal structural materials (SM) with BCC (ferrite-martensitic steels, alloys of vanadium, etc.) and FCC (austenitic steels, etc.) crystal lattices in the conditions of “before – after – during” of a low-temperature damaging irradiation are examined. The qualitative and quantitative distinctions of the states and properties of SM “before – after” (an equilibrium static state) and “during” (essentially nonequilibrium dynamic state) of irradiation are demonstrated. Depending on the rigidity of the stress-deformed state, type of a crystal lattice, the low-temperature yield strength, mobility of dislocations and temperature in SM there can be different modes of the plastic deformations with the brittle fracture by rupture or shear (cold brittleness). The conditions (control parameters) for occurrence of the cold brittleness, including formation of the critical cracks of rupture and shear, generating dislocations, high low-temperature yield strength, high starting stress for movement of dislocations and low level of viscous braking of the dislocations (“dry” friction mode) in the dynamic area of their mobility on the fronts of cracks of rupture or shear, are defined. The conditions for occurrence of the cold brittleness can be implemented in BCC SM, defining their temperature areas of the cold brittleness, and are not implemented in FCC SM (the cold brittleness is absent). “During” of irradiation in BCC SM the state of irradiation cold brittleness with a brittle fracture by rupture or shear is not formed (the radiation cold brittleness is absent). Possibilities and difficulties are discussed for development of the physical models and computer modeling of the radiation structures, defects and physical-mechanical properties of the SM, determined and controlled by integration of the physical laws of a macrosystem and a quantum (atomic) microsystem. For clarification (specification) of the mechanisms for formation of the radiation structures and properties of SM and development of the corresponding quantitative models, the results of the experimental research of SM “during” of a neutron irradiation are required.

Key words: nuclear and thermonuclear reactors, structural materials, low temperature damaging irradiation, physical and mechanical properties, brittle fracture, cold brittleness.

O. A. Gurova, T. I. Guzeeva

Dependence of physical and chemical properties of hydroxyapatite powder on the method of its preparation was revealed in the present work. Samples produced from biological raw materials by methods of annealing and demineralization of cattle bones were studied. Hydroxyapatite powders surface was studied by scanning electron microscopy, particle size distribution histograms and specific surface area values were obtained. Phase composition of the studied materials was determined by X-ray phase analysis. Comparative analysis of physical and chemical properties of hydroxyapatite samples obtained by different methods was carried out and a method of producing the ultra-dispersed hydroxyapatite powder with controlled particle sizes and Ca/P ratio close to stoichiometric one in human bone tissue was developed. It was shown that hydroxyapatite powders produced by cattle bones demineralization method with 1M and 2M hydrogen chloride aqueous solutions had the best physical and chemical properties in terms of practical application in medicine. Those powders had the smallest particle size and the highest specific surface area values.

Keywords: hydroxyapatite, X-ray phase analysis, internal standard method, phase composition, stoichiometric composition, scanning electron microscopy.

Influence of biodestruction on deformation-strength properties of polymer composites based on secondary polypropylene and natural components of plant origin

M. V. Bazunova, R. K. Fakhretdinov, L. R. Galiev, A. S. Shurshina,
A. R. Sadritdinov, E. I. Kulish, V. P. Zakharov

Complex study of the effect of the degree of biodegradation on the change in the deformation-strength characteristics of polymeric composite materials based on secondary polypropylene and natural fillers of plant origin (wood meal and buckwheat husk) was carried out for the first time. When studying the weight loss of polymeric composites based on secondary polypropylene from various manufacturers, filled with natural components of plant origin as a result of destructive processes under the influence of microorganisms, it was established that the nature of the plant filler practically does not affect the ability to biodegradable. The content of the filler has a greater effect on biodegradation. The type of polymer binder (secondary polypropylene of different grades) has no significant effect on biodegradability, at least for a given period of exposure in the soil. It is established that no significant changes in the deformation-strength properties of polymeric compositions based on secondary polypropylene are observed until two months of exposure in the soil. After three months of contact with the soil, all the compositions studied in the entire range of plant filler content show a deterioration in the deformation-strength characteristics. Consequently, polymer compositions based on secondary polypropylene with natural fillers of plant origin, even after contact with soil microorganisms for two months can be recycled.

Keywords: biodegradable polymeric composites, recycling, secondary polypropylene, modulus of elasticity, breaking elongation, breaking stress.

based on zirconia

V. V. Smirnov, S. V. Smirnov, A. I. Krylov, T. O. Obolkina,
O. S. Antonova, S. M. Barinov

The results of the sintering of zirconium ceramics containing additives forming low-temperature melts are presented. To obtain low-temperature ceramic materials based on ZrO2, nanodispersed powder of a high specific surface area of 90 – 120 m2/g, containing 3, 6 and 9 mol. % Y2O3 was used. As additives, multicomponent compositions were used to form melts based on silicates and niobates of alkali metals (Li, Na, K), melting point of 1000 to 1400 °C. Additives were injected into the powder ZrO2 in an amount of 1, 2, 5 and 10 wt. %, With vigorous stirring in a planetary mill with zirconia balls. Sintering of ceramics to a dense state was at low temperatures of 1250 – 1500 °C. The obtained materials were characterized by a crystal size from 50 to 800 nm. The effect of the amount of sintering additives and the stabilizing additive on the phase composition, microstructure and strength was studied. The most durable materials for bending up to 500 MPa were obtained by sintering up to 1350 °C with the addition of lithium niobate in an amount of 5 wt. % (yttrium oxide content of 9 mol. %).

Keywords: zirconia, ceramics, sintering, strength, microstructure, phase composition.

Effect of structure on mechanical and tribological properties of sintered (Al – 12 Si) – 40 Sn alloy

N. M. Rusin, A. L. Skorentsev

The relationship of the structure of the (Al – 12 Si) – 40 Sn composite alloy with its mechanical and tribological properties was the object of the current work. The alloy was obtained by liquid-phase sintering of powder briquettes made of the mixture of tin (PT-2) and Al-12Si eutectic alloy powders. The sintering was carried out at a temperature below the melting point of the eutectic, since at higher temperatures the sample melted and lost its shape. It was found that the above sintering temperature doesn´t allow to obtain the samples with high density. The residual porosity of the samples was 6 – 8 % and didn´t practically decrease with the increasing of sintering time. The obtained material had low mechanical properties, which slightly improved with increasing sintering time up to two hours. At the same time, the evaporation of tin was increased noticeably. Taking into account the undesirable phenomena that occur during prolonged exposure of the samples at high temperature, the hot densification was carried out after the short-time sintering. The densification of the sintered samples in order to eliminate their residual porosity was conducted in the closed mold under pressure above the ultimate strength of the alloy. It was established that such operation contributed to a significant improvement not only in the strength, but also in the ductility of the studied material. In addition, the obtained non-porous material had high wear resistant under the dry friction against steel counterbody, especially noticeable during the friction under the high pressure. The wear rate of samples with the Al – Si matrix was 30 % lower than that of the alloy with the matrix of pure aluminum.

Chemical vapor deposition of wear-resistant iron-nickel coating on precision parts of hydraulic systems
L. V. Kozyreva, V. V. Kozyrev, N. N. Chupyatov

The application of wear-resistant coating for hardening for precision parts of hydraulic systems working in abrasive and corrosive-mechanical wear conditions is one of the important directions of research into increasing the service life of road construction, logging, agricultural and other types of equipment. However, on hardening of precision parts on metallization of the parts surface is necessary to provide a coating that is effective in achieving optimum adhesion strength, microhardness and roughness. This article describes the results of scientific and research investigations of the team of authors to develop a wear- resistant iron-nickel coating by the method of chemical vapor deposition of nickel tetracarbonyl and iron pentacarbonyl. A method of applying a wear-resistant iron-nickel coating on precision parts, in which a nickel coating layer with a thickness to 10 mcm is first applied to the part surface by feeding nickel tetracarbonyl vapour to the part surface heating, followed by applying an iron-nickel coating layer by feeding a mixture of nickel tetracarbonyl vapour, iron pentacarbonyl and carbon monoxide in a volume ratio of 1:6:15, with thermal decomposition of the nickel tetracarbonyl vapour and iron pentacarbonyl. This confirms the efficiency of the approaches used in this case which increases the wear resistance of precision parts of hydraulic systems and increases the service life of machines.
