Characterization of Ti-B-C-N films deposited by dc magnetron sputtering of bicomponent Ti/B4C target
Journal of Superhard Materials - Tập 37 - Trang 14-20 - 2015
A. A. Onoprienko, V. I. Ivashchenko, I. I. Timofeeva, A. K. Sinelnitchenko, O. A. Butenko
Quaternary Ti-B-C-N films have been deposited onto Si (100) substrates by dc magnetron sputtering of bi-component Ti/B4C target in an Ar/N2 gas mixture with different amounts of nitrogen in the mixture (from 0 to 50%). The X-ray diffraction, X-ray photoelectron spectroscopy, indentation, and scratch tests have been employed to characterize the films. The films have been found to have the nano-comp... hiện toàn bộ

Wear resistance of nano-polycrystalline diamond with various hexagonal diamond contents
Journal of Superhard Materials - Tập 34 - Trang 343-349 - 2013
A. Kurio, Y. Tanaka, H. Sumiya, T. Irifune, T. Shinmei, H. Ohfuji, H. Kagi
Wear resistance of nano-polycrystalline diamond (NPD) rods containing various amounts of hexagonal diamond has been tested with a new method for practical evaluation of the wear-resistance rate of superhard ceramics, in addition to the measurements of their Knoop hardness. The wear resistance of NPD has been found to increase with increasing synthesis temperature and accordingly decreasing proport... hiện toàn bộ
Thermodynamics of the interaction of a group of nanoparticles with a macrophase
Journal of Superhard Materials - Tập 30 - Trang 379-383 - 2009
A. F. Lisovskii
An expression describing the variation of the Gibbs potential for a system consisting of a group of nanoparticles and a macrophase has been derived. It has been shown that in this system there are diffusion flows of the substance from nanoparticles to the macrophase. The conditions have been defined, under which a nanoparticle or a group of nanoparticles can be in an equilibrium state and maintain... hiện toàn bộ
Production of Polycrystalline Materials by Sintering of Nanodispersed Diamond Nanopowders at High Pressure. Review
Journal of Superhard Materials - Tập 40 - Trang 325-334 - 2018
O. O. Bochechka
The investigations dealing with the problems of forming polycrystalline materials with a high level of physical-and-mechanical properties using the method of diamond powder sintering at high pressure have been considered. The compacting mechanism of diamond nanopowders of different genesis under exposure to high pressure and high temperature is described, special features of pore structure formati... hiện toàn bộ

Special features of magnetoresistance in nanostructural diamond compacts
Journal of Superhard Materials - Tập 33 - Trang 29-33 - 2011
V. M. Dmitriev, A. V. Terekhov, V. N. Uvarov, A. D. Shevchenko, J. Cwik, A. A. Shul’zhenko, A. N. Sokolov, D. S. Kondrashov
The results of the investigation into the behavior of resistivity of nanostructural diamond composites produced by thermobaric treatment of various nanodiamond powders over a wide range of temperatures and external magnetic fields have been considered. It has been found that the conductivity of nanostructural diamond compacts does not depend on the presence of impurity atoms in samples and may be ... hiện toàn bộ
Adsorption properties of shungite in purification of water–alcohol solutions
Journal of Superhard Materials - - 2018
L. M. Mel’nik, N. A. Tkachuk, O. V. Turchun, V. E. Diyuk, O. V. Ischenko, O. O. Byeda, L. D. Kisterska, O. B. Loginova, S. O. Lysovenko, O. G. Gontar, V. V. Garashchenko
Shungite adsorption properties to remove higher alcohols and other impurities from water–alcohol solutions is studied by the methods of nitrogen adsorption, thermogravimetric analysis, wetting, temperature-programmed desorption mass spectrometry, and FTIR spectroscopy. Shungite is shown to be able to effectively sorb impurities from water-alcohol solutions to form fairly strong adsorption systems.... hiện toàn bộ
Simulation of novel superhard carbon materials based on fullerenes and nanotubes
Journal of Superhard Materials - Tập 32 - Trang 67-87 - 2010
V. V. Ivanovskaya, A. L. Ivanovskii
The state-of-the-art in theoretical research directed at the search for superhard materials based on carbon fullerenes and nanotubes has been briefly reviewed. The data available on elastic properties of the main groups of condensed phases that form due to the interaction of fullerenes or (and) nanotubes because of both weak (of the van der Waals type) bonds and polymerization to form strong coval... hiện toàn bộ
