We have analyzed the surface of a plasma three-dimensional capillary-porous (TDCP) Ti coating with an additional bioactive hydroxyapatite coating formed by microplasma oxidation (MPO). Scanning electron microscopy (SEM) was used to analyze the open porosity of these composite coatings. The surface of the TDCP Ti coating consists of ridges and valleys. The main porosity of the TDCP Ti coating is co...... hiện toàn bộ
Effect of Boron Microalloying on the Structure and Properties of a Welded Joint Made of a Flux-Cored Wire for Welding of Flat-Rolled High-Strength Steel Plates with a Standard Yield Stress of 750 MPa

P. V. Melnikov, V. V. Gezha, G. D. Motovilina, V. A. Mogilnikov
Abstract—The effect of the boron microalloying on the structure and mechanical properties of a weld of high-strength steel with a standard yield stress of 750 MPa has been studied. On the basis of the results, a flux-cored wire of brand 48PP-69 has been developed.
Effect of t-ZrO2-Based Ceramic Samples on the Condition of Muscular and Connecting Tissues in Experimental Animals with Intramuscular Introduction
Inorganic Materials: Applied Research - Tập 10 - Trang 1109-1114 - 2019
N. Yu. Kovalko, M. V. Kalinina, D. N. Suslov, O. V. Galibin, G. Yu. Yukina, M. Yu. Arsentyev, O. A. Shilova
A highly dispersed powder (9–10 nm) based on a tetragonal solid solution of partially stabilized zirconia (t-ZrO2) was synthesized by coprecipitation of hydroxides from salt solutions. On the basis of this powder, nanocrystalline ceramic (grain size 60–70 nm) with high physicochemical and mechanical characteristics was obtained: degree of tetragonality c/a, 1.438–1.431; flexural strength, 900–1000...... hiện toàn bộ
Effect of Implantation of Argon and Oxygen Ions on the Physicochemical Properties and Corrosion and Electrochemical Behavior of 14Cr17Ni2 Chromium–Nickel Steel

The effect that implantation of argon and oxygen ions (both individually and in combination) has on the physicochemical structure of the surface of 14Cr17Ni2 steel and its corrosion and electrochemical behavior is studied by linear sweep voltammetry (polarization curve measurements), atomic force microscopy, and X-ray photoelectron spectroscopy. Treatment with Ar+ ions results is enrichment of the...... hiện toàn bộ
Thermoelectric and Elastic Properties of Carbon Nanotubes Irradiated with High-Energy Electrons

G. Yu. Mikhailova, M. M. Nishchenko, V. N. Pimenov, E. E. Starostin, V. I. Tovtin
Abstract—The electrical conductivity, thermo-emf, and elasticity coefficient were experimentally studied in multilayered carbon nanotubes (CNTs) exposed to room-temperature irradiation. The initial CNTs with dimensions of 18 ± 7 nm were obtained via chemical vapor deposition using propane–butane as precursor. The irradiation of CNTs was implemented on Mikrotron-ST cyclic electron accelerator at th...... hiện toàn bộ
Synthesis of the Materials with a Switchable Wettability Based on Photosensitive Terpolymers Containing Poly(Titanium Oxide)

In this paper, we synthesized the organic–inorganic terpolymers based on poly(titanium oxide) ((≡TiO)n), hydroxyethyl methacrylate (HEMA), and various organic vinyl monomers (styrene, vinylbutyl ether, butyl methacrylate, isobornyl acrylate, 2-ethylhexyl acrylate, acrylonitrile, and methyl methacrylate) by using a polycondensation-polymerization method. Independent of the composition, the terpolym...... hiện toàn bộ

Photoluminescence spectra and kinetics have been studied for finely dispersed powders of such luminophores as SrAl2O4:(Eu2+,Dy3+) and Sr4Al14O25:(Eu2+,Dy3+,B). Several lasers with different wavelengths (λ = 355, 404, 440 and 530 nm) were used for the excitation of photoluminescence. The photoluminescence of the materials is revealed to occur in a long-wave spectral range from 550 to 750 μm, which ...... hiện toàn bộ
