Heating of Particles with an Aluminum Core and a Hydroxide Shell
Pleiades 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
A Study of the Corrosion Resistance of Pump–Compressor Pipes with a Diffusion Zinc Coating under the Complicated Conditions of Gas-Producing Wells
Pleiades Publishing Ltd - Tập 53 - Trang 1288-1294 - 2018
E. V. Proskurkin, D. A. Sukhomlin
The results of corrosion tests of diffusion zinc coatings under the complicated corrosion and erosion conditions of gas-production wells are presented. The slowdown of the anodic process of the solution of a coating and its salt passivation in model solutions was shown by the electrochemical research. It was established that the corrosion rates of diffusion zinc-coated 36G2F steel samples were 4.1...... hiện toàn bộ
Regularities of formation of the structure of Al-containing nanocomposites upon interaction of ASD-6 powder with polymer suspension
Pleiades Publishing Ltd - Tập 49 - Trang 869-873 - 2013
N. M. Antonova, D. P. Babichev, V. Yu. Dorofeev
A new approach toward development of nanosize materials based on water-soluble polymers is suggested. Nanosize aluminum-containing structures screened by a polymer sodium carboxymethyl cellulose shell are obtained at temperatures of 70–80°C by introducing Al microparticles with a size of up to 10 μm into an aqueous solution of sodium carboxymethyl cellulose. The methods of XRD and IR spectroscopy ...... hiện toàn bộ
Elevated Temperature Wear Behavior of FeCr Slag Coating as an Alternative Coating Material for Caster Rolls
Pleiades 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
Plasma-electrolytic oxidation of valve metals in Zr(IV)-containing electrolytes
Pleiades 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
Thermodynamics of Methane Adsorption in a Microporous Carbon Adsorbent Prepared From Polymer Composition
Pleiades Publishing Ltd - Tập 57 - Trang 883-889 - 2021
I. E. Men’shchikov, A. A. Fomkin, A. V. Shkolin
Carbon microporous adsorbents obtained on the basis of polymers are promising adsorbents for the tasks of adsorption storage of natural gas due to the possibility of creating a precise porous structure, as well as optimal mechanical characteristics. A study of the adsorption of methane in a carbon adsorbent based on a composite polymer of furfural and epoxy resin in the temperature range from 178 ...... hiện toàn bộ
Study of inhibition effect of pyridinium salt derivative on corrosion of C1010 carbon steel in saline solution
Pleiades Publishing Ltd - Tập 52 - Trang 714-720 - 2016
Mehdi Salih Shihab, Mehdi Honarvar Nazari, Laura Fay
In this work, pyridinium dibromide (2) was synthesized and its structure was confirmed using spectroscopic techniques. Compound (2) was successfully applied as a corrosion inhibitor for C1010 carbon steel in 3.5% NaCl solution at 25°C. Different electrochemical measurements such as potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) were used to evaluate different ...... hiện toàn bộ
The Influence of Hydrocarbonate Ions on the Anodic Behavior of Aluminum at Different Temperatures
Pleiades Publishing Ltd - Tập 53 - Trang 1199-1204 - 2018
S. A. Kaluzhina, E. N. Aksyonova, T. A. Minakova
The influence of thermal conditions on the anodic behavior of aluminum in sodium hydrocarbonate solutions of various concentrations was studied. The concentration and temperature limits of local activation in the studied systems are established. The effect of the thermal activation of self-dissolving metal is found.
