Production of dispersed powders of tungsten-cobalt by spark erosion dispersion of compact samples of hard alloys, including scrapSurface Engineering and Applied Electrochemistry - - 2015
A. D. Verkhoturov, M. I. Dvornik, T. B. Ershova, A. V. Zaitsev
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
