Induction centrifugal deposition method of the charge on the basis of tin-bronze powder with additives of fine boehmite grains is described in this report. This paper also shows the experimental results of metallographic investigations and tribological tests of produced specimens. During the experimental work, the optimal ratio of the mixture components, which increases the anti-friction properties of the bronze coating have been identified. Based on the analysis of induction centrifugal deposition regimes it has been found that the fine boehmite grains are converted into nano grains alumina.

The authors investigated aspects of nanocomposite structure formation in Fe+Al+Fe2O3 and Fe+Al+Cr2O3 powder mixtures during combustion synthesis using precursors formed as a result of mechanochemical interaction at the stage of preliminary mechanical activation of reactive mixtures. Despite the significant difference in thermal effects, two types of reactions (aluminothermic reduction of oxides and formation of intermetallics from elements, though in the trace amounts) can take place during mechanical activation. Local chemical concentrations at the interfaces and quick reaction kinetics in the nanometer scaled diffusion couples are probably responsible for the simultaneous passing the reactions in mechanically activated mixtures. Nanocomposite structure of the precursors with fine alumina inclusions allows forming end products inheriting structural morphology of the precursors in toto. Complete reduction of oxides with aluminum at the stage of mechanical activation is not a necessary condition for nanostructure preservation during the following self-propagating high-temperature synthesis. The last one is probably connected with the high rate of heterogeneous nucleation at the early stage of combustion and the optimized heat evolution and cooling conditions.

The basic properties of the consolidated titanium powder materials obtained by two methods of electrical pulse sintering and conventional vacuum sintering were investigated. Titanium powder consists of spherical and nonspherical forms and has the distribution of the particle size 200-400 microns. The powdered composition consolidated by two different methods consists of 20-30% nonspherical particles (the rest are spherical particles) has 5-7 times higher permeability compared to the spherical powder composition. Conventional vacuum sintering method allows manufacturing of consolidated samples within 60-70. minutes at the sintering temperature of 1000-1200°C. Electrical pulse sintering produces the samples with the same properties within 70-80. μs. © 2016 Elsevier Ltd.

This paper presents the results of research aimed at design of multilayer asymmetric oxygen separation membranes comprised of functionally graded by composition and porosity nanocomposite layers with mixed ionic-electronic conductivity (MIEC) and a high oxygen mobility supported on the compressed Ni-Al alloy foam substrate. Complex oxides with fluorite-like structure (Ce 0.9Gd0.1O2-δ), perovskite-like structure La0.8Sr0.2Fe1-xNixO 3-δ (x = 0.3-0.4) and spinel structure MnFe2O 4 synthesized via polymerized precursors (Pechini) route were used for the preparation of these nanocomposites by ultrasonic dispersion of their mixtures in isopropanol with addition of polyvinyl butyral. Parameters characterizing their oxygen mobility and reactivity were estimated by oxygen isotope heteroexchange, weight loss transients, temperature-programmed reduction by CH4 and reoxidation by CO2. Membranes were prepared by successively supporting on one side of substrate macroporous-mesoporous- microporous-dense layers of MIEC nanocomposites finally covered by a porous layer of La-Ni-Pt/Pr0.3Ce0.35Zr0.35O 2-x catalyst. Preliminary tests of this membrane in the lab-scale reactor in the process of methane selective oxidation/oxi-dry reforming into syngas demonstrated their oxygen permeability and performance promising for the practical application. © 2010 Elsevier B.V.

A conventional Ni + YSZ/YSZ anode half-cell (the Research Center Jülich) and the Ni + YSZ/YSZ planar half cell washcoated by a layer of the Ru + Ni-doped perovskite-based nanocomposite (Ru + Ni/LaPrMnCr/YSZ) were compared in terms of their activities and selectivities in the steam reforming of methane. The kinetic measurements were carried out in a laboratory scale plate-type reactor, and results were interpreted using computational models. A power-law kinetic model was verified against the experimental data, and parameters were estimated. Both numerical prediction and experimental testing indicate that the nanocomposite coated Ni + YSZ/YSZ plate shows much better catalytic performance under the middle-temperature operating conditions. CFD simulations show that for the high activity of thermally conductive catalytic plates, superior heat transfer performance is observed in the lab-scale reactor. The lab-scale data were successfully up-scaled for the case of steam reforming of natural gas on a structured catalyst at realistic operation conditions. Up to 700 °C, the pilot test data obtained with the structured catalyst comprised of three stacked parallel Ni-Al plates (50 × 50 × 1 mm) coated with perovskite-based nanocomposite correlate quite good with the 1-D plug-flow reactor model predictions assuming the proposed kinetics.

Titanium foams were manufactured by compacting spherical carbamide granules (as space holder) coated with titanium powder, leaching the space holder and sintering. A simple method was used to prepare composite (i.e. coated carbamide) granules. Foams with porosities in the range of 65-85% were prepared, which exhibited improved mechanical properties compared to titanium foams prepared by compacting simple mixtures of powder and space holder. The property improvements in the present material are attributed to achievement of more regular pore structure in the foams. © 2012 Elsevier B.V. All rights reserved.

Modes of pressing, sintering and electric pulse treatment of hard alloy powder material from tungsten carbide with cobalt binder with power frequency currents have been studied. The results of metallography have shown that the established regimes of electropulse treatments resulted in a change in the structural-phase state of the sintered powder material based on tungsten carbide. In this case the change of structural-phase state of this material manifested in reducing the content of carbon and fragile η-phase therein and in reducing porosity. The result of this structural-phase change was the increase in strength of the sintered powder material based on tungsten carbide. For comparison, we produced tungsten carbide - cobalt alloy by the method high voltage electric discharge consolidation of WC-Co powder. This hard alloy also has a fine grain structure and a high strength.

One of the objectives of porous powder materials (PPM) research for the majority of authors is getting their anisotropic structure in the direction of gas or liquid flow and thereby increasing the per-meability of PPM, while keeping the average pore size due to such structure. In this paper we investi-gate the effect of increasing the surface layer porosity of PPM samples obtained by pressure mould-ing of sponge titanium powder with steel punch with elastic lining. Measurement of the porosity using PPM sample thickness was performed by the stereometric quantitative metallography method (meth-od of parallel secants) from the surface in contact with the formative tool to a depth of 2.0 mm from this surface with an interval of 0.1 mm. The depth at which this effect is most pronounced (up to 0.8 - 1.0 particle diameter) has been established, as well as the specific values of porosity in the PPM at this depth.
