Документ Carbon Steel (St.3) Corrosion Caused by the Circulating Water Flow(Kyiv National University of Technologies and Design, 2018) Pilipenko, A. I.; Pancheva, H.; Khrystych, E. V.; Smirnova, O. L.Документ Influence of the magnitude of the bias potential and thickness of the layers on the structure, substructure, stress-deformed state and mechanical (TiMo)N/(TiSi)N coatingsl characteristics of vacuum-arc multi-layered(2020) Sobol, O. V.; Postelnyk, H. O.; Meylekhov, A. A.; Subbotina, V. V.; Stolbovoy, V. A.; Dolomanov, A. V.; Kolesnikov, D. A.; Kovaleva, M. G.; Sukhorukova, Yu. V.Layers based on titanium nitride doped with molybdenum and silicon were used to create a multilayer composite. In this case, the mismatch between the lattice periods of (TiMo)N and (TiSi)N layers was about 1%. It was found that in the (TiMo)N/(TiSi)N multilayer composite, such a mismatch of the periods in the constituent layers does not change the single-phase state of the composite even at relatively large layer thicknesses (about 350 nm). The creation of a (TiMo)N/(TiSi)N composite with a nanometer layer thickness allows one to reduce the magnitude of macrostresses (a large value of which is characteristic of single-layer (TiMo)N coatings) and change the substructural characteristics in a wide range of values. It has been established that the use of multi-element (TiMo)N and (TiSi)N layers in a multilayer coating design allows one to achieve a high-hard state with high adhesive strength and good tribological characteristics. The highest properties (hardness – 34.8 GPa and adhesive strength 166.09 N) were achieved in coatings obtained at Ub = -200 V and a layer thickness of 80 nm, which are characterized by compression macrostresses of 7.85 GPa and microstrains 0.75%.Документ The use of negative bias potential for structural engineering of vacuum-arc nitride coatings based on high-entropy alloys(2019) Sobol, O. V.; Andreev, A. A.; Gorban, V. F.; Postelnyk, H. O.; Stolbovoy, V. A.; Zvyagolsky, A. V.; Dolomanov, A. V.; Kraievska, Zh. V.The effect of negative bias potential (Ub = -40, -110, and -200 V) during the deposition of multi-element coatings on their composition, structure and mechanical properties was studied. It was established that during the transition from a multi-element alloy to a nitride, a single-phase state possible to form on its basis (based on the fcc metal lattice, structural type NaCl). In this case, the composition (FeCoNiCuAlCrV)N of coatings with increasing Ub is depleted by the element with the lowest enthalpy of formation of nitride (Cu). In (AlCrTiNbSi)N and (AlCrTiZrNbV)N coatings, the content of low-mass elements (Si and Al) decreases with increasing Ub. In (TiZrHfVNb)N coatings of strong nitride-forming elements with increasing Ub to 200 V, the composition practically does not change. The structure of such coatings is characterized by the presence of a texture with the [111] axis. The presence of weak nitride-forming elements in (FeCoNiCuAlCrV)N coatings leads to the formation of texture [110] for large Ub = 110…200 V. In such coatings, the hardness does not exceed 35 GPa. It is shown that to achieve high hardness at high Ub it is necessary to increase the content in the high-entropy alloy of elements with high nitride-forming ability. In this case, in (TiZrHfVNb)N coatings (made of strong nitride-forming elements with a large mass) at Ub = 200 V, the hardness exceeds 45 GPa.Документ The use of plasma-based deposition with ion implantation technology to produce superhard molybdenum-based coatings in a mixed (C2H2+N2) atmosphere(2018) Sobol, O. V.; Andreev, A. A.; Mygushchenko, R. P.; Beresnev, V. M.; Meylekhov, A. A.; Postelnyk, A. A.; Kravchenko, S. A.; Tabaza, Taha. A.; Al-Qawabah, Safwan M.; Al-Qawabeha, Ubeidulla F.; Stolbovoy, V. A.; Serdyuk, I. V.; Kolesnikov, D. A.; Kovaleva, M. G.The influence of the pressure of a mixed gaseous atmosphere (80%C2H2+20%N2) and the supply of a high-voltage negative potential in a pulsed form on the elemental and phase composition, structure and physico-mechanical characteristics of the vacuum-arc molybdenum-based coatings. It is shown that in the temperature deposition range 400…550 °С as a result of plasma-chemical reactions, the maximum nitrogen atoms content in the coating does not exceed 1.5 at.%. It is found, that at the maximum pressure of РC2H2+N2= 2.3∙10-1 Pа when the γ-MoC phase is formed, an superhard state of 50.5 GPa (at a constant potential -200 V, without additional high-voltage pulse action) and 51.1 GPa (at a constant potential -200 V, with additional high-voltage pulse action) is reached.Документ Film evaporators to be used with crystallized solutions(Національний технічний університет "Харківський політехнічний інститут", 2020) Koshelnik, O.
