Heating of Particles with an Aluminum Core and a Hydroxide ShellPleiades Publishing Ltd - Tập 59 - Trang 57-67 - 2023
N. S. Shaitura, V. V. Artemov, M. N. Larichev
Particles with an aluminum core and a hydroxide shell obtained by low-temperature (up to 100°C) oxidation of spherical aluminum micron particles with water are studied. Processes occurring upon heating these particles up to 750°C in a controlled gaseous atmosphere are analyzed. The composition and amount of released gas-phase products are studied, and their nature is determined. The transformation...... hiện toàn bộ

The influence of the essence of surface on mass spectrometry behavior of the medication, i.e., pentoxifylline, in the course of surface-enhanced laser desorption/ionization. For surfaces, we used a standard stainless-steel target for mass-spectrometric analysis using matrix-assisted laser desorption/ionization, AnchorChip, and the surfaces of pentoxifylline tablets. The influence of adding α-cyano...... hiện toàn bộ
Elevated Temperature Wear Behavior of FeCr Slag Coating as an Alternative Coating Material for Caster RollsPleiades Publishing Ltd - Tập 58 - Trang 119-128 - 2022
Yılmaz Küçük, Mecit Öge
The aim of this study is to show that ferrochrome (FeCr) slag, an industrial waste material, can be used as an alternative protective coating material in service conditions for the caster roll surfaces used in the continuous casting line of steelmaking. Atmospheric plasma spray (APS) method was utilized in coating processes. Considering the working conditions of continuous casting production line,...... hiện toàn bộ
The effect of diffusion processes on surface smoothing upon chemical polishing of titaniumPleiades Publishing Ltd - Tập 52 - Trang 947-953 - 2016
E. V. Dogadkina, M. G. Dontsov, V. I. Parfenyuk
The influence of diffusion currents on surface smoothing is investigated upon chemical polishing of titanium. The dependence between the oxidizer and activator maintenance in a solution of chemical polishing, value diffusion currents, and efficiency of surface smoothing is revealed. It is shown that the increasing temperature of the solution increases the efficiency of surface smoothing.
Biocidal and Corrosion Properties of Composite Electrochemical Coatings Based on Tin–Nickel AlloyPleiades Publishing Ltd - Tập 59 - Trang 305-311 - 2023

Composite electrochemical coatings based on a tin–nickel alloy with a composite of the “SiO2 core–TiO2 shell” type have been obtained. Corrosion properties of coatings were studied in 3% sodium chloride solution. Biocidal properties of coatings with respect to Escherichia coli ATCC 8739 and Staphylococcus aureus ATCC 6538 strains were studied. It was found that, to impart biocidal properties to th...... hiện toàn bộ
Plasma-electrolytic oxidation of valve metals in Zr(IV)-containing electrolytesPleiades Publishing Ltd - Tập 46 - Trang 456-462 - 2010
V. S. Rudnev, T. P. Yarovaya, K. N. Kilin, I. V. Malyshev
The studies devoted to the production of Zr-containing coatings on valve metals (Ti, Al, and Mg) using plasma-electrolytic oxidation are reviewed. The coatings are formed from aqueous electrolyte suspensions containing dispersed ZrO2 particles, as well as Zr(IV) fluorocomplexes, polyphosphate, and tartrate complexes, and from Zr(SO4)2 electrolytes. The layers that contain both zirconium oxide in e...... hiện toàn bộ
Photorefractive properties of composites based on polyvinyl alcohol, single-wall carbon nanotubes, and fullerenePleiades Publishing Ltd - - 2016
A. D. Grishina, T. V. Krivenko, V. V. Savel’ev, A. V. Vannikov
Composites with photoelectrical, nonlinear optical, and photorefractive properties have been prepared. The composites consist of polyvinyl alcohol, single-wall carbon nanotubes, and fullerene C60. Addition of C60 with a long wavelength boundary near 630 nm resulted in an eight- to tenfold increase in both the quantum efficiency of generation of mobile hole charges and the photorefractive two beam ...... hiện toàn bộ
