Intensifying the Processes of Polysaccharide Extraction from Plant Raw Materials under the Action of an Electric CurrentSurface Engineering and Applied Electrochemistry - Tập 58 - Trang 402-411 - 2022
A. P. Malyushevskaya, V. N. Tsurkin, A. V. Ivanov, A. N. Yushchishina
The article presents the results of the studies into the intensification of the processes of extraction of water-soluble polysaccharides from plant raw materials—medicinal hyssop (Hyssopus officialis L.)—under the action of an electric current. The effect of direct, alternating, and pulsed electric currents on the degree of polysaccharides’ extraction was studied in comparison with the traditional...... hiện toàn bộ
Production of dispersed powders of tungsten-cobalt by spark erosion dispersion of compact samples of hard alloys, including scrapSurface Engineering and Applied Electrochemistry - - 2015

The processes of the influence of electrical low voltage discharges on compact samples of tungsten-containing hard alloys and the conditions of producing composite powders with a fixed phase and chemical composition and size grading are considered. The obtained results have been used to manufacture dispersed powders of tungsten-cobalt hard alloys by spark erosion dispersion of compact scrap and re...... hiện toàn bộ
Electrolytic binary metal-oxide compounds: Fundamental peculiarities of their structure and formationSurface Engineering and Applied Electrochemistry - Tập 49 - Trang 368-372 - 2013
V. M. Nagirnyi, R. D. Apostolova, S. V. Petrichenko
Based on the experimental results and the data published in the literature, the specific features and qualitative distinctions of electrolytic binary metal-oxide systems (such as V-Mn, Co-Ni, Co-Cr, Mn-Ni, and Mn-Cr) from the individual oxides contained in them are studied. In a binary system, these oxides react to form a complex structurally homogeneous conglomerate. The precipitates of the binar...... hiện toàn bộ
Anode plasma electrolytic boronitrocarburising of low-carbon steelSurface Engineering and Applied Electrochemistry - Tập 51 - Trang 462-467 - 2015
S. A. Kusmanov, I. V. Tambovskiy, A. R. Naumov, I. G. Dyakov, P. N. Belkin
Multicomponent saturation of low-carbon steel with carbon, nitrogen, and boron was investigated under the anode plasma electrolytic treatment. Optical and scanning electron microscopes with an energy dispersive attachment were used to characterize the composition of the modified layer and its surface morphology. Surface roughness and microhardness were studied with a profilometer–profilograph and ...... hiện toàn bộ
Plasma electrolytic hardening of steels: ReviewSurface Engineering and Applied Electrochemistry - Tập 52 - Trang 531-546 - 2017
P. N. Belkin, S. A. Kusmanov
Research data on plasma electrolytic hardening of steels in aqueous solutions are analysed with an emphasis on the features of the hardened layer formation and the processing conditions, as well as on electrolyte compositions providing new technological opportunities. The influence of the treatment regimes on the temperature and heating rate of cylindrical samples are described. The methods of har...... hiện toàn bộ
Peculiarities of Control over Electron-Beam Additive Form ManufacturingSurface Engineering and Applied Electrochemistry - Tập 55 - Trang 232-240 - 2019
A. V. Shcherbakov, R. V. Rodyakina, A. S. Kozhechenko, N. M. Vakhmyanin, D. A. Gaponova, V. P. Rubtsov
This work analyzes the manufacturing process of an electron-beam additive form by heating as a result of remelting the supplied filler wire as a control object. Control actions and output values are designated that can be used in constructing a control systems with feedback. A mathematical modeling technique is used to study heat transfer in a nonstationary formulation, taking into account the inf...... hiện toàn bộ
