control of Glow Discharge parameters using transverse supersonic gas flow numerical experiment
Journal of Physics: Conference Series, 2014Co-Authors: A I Saifutdinov, B A Timerkaev, B R ZalyalievAbstract:A low pressure Glow Discharge in a transverse supersonic gas flow was studied by numerical modelling for the case where the flow only partially fills the interelectrode gap. It's shown that by organizing a supersonic gas flow in a limited region of the interelectrode space can be controlled combustion conditions of the Glow Discharge, and its parameters. It is shown that it is possible to achieve stable combustion Glow Discharge at low and superlow pressures, when the parameter pL lies on the left branch of the Paschen curve.

Glow Discharge in a transverse supersonic gas flow at low pressures
High Temperature, 2014Co-Authors: B A Timerkaev, B R ZalyalievAbstract:A low-pressure Glow Discharge in a transverse supersonic gas flow was experimentally studied for the case where the flow only partially fills the interelectrode gap. It is shown that the space region with supersonic gas flow has a higher concentration of gas particles and, therefore, works as a charged particle generator. The near-electrode regions of Glow Discharge are concentrated specifically in this region. This structure of Glow Discharge is promising for plasma deposition of coatings under ultralow pressures.

Normal Glow Discharge between curvilinear electrodes
Journal of Physics: Conference Series, 2018Co-Authors: Sergey SurzhikovAbstract:A diffusion-drift calculation model of a normal Glow Discharge between curvilinear electrodes is presented. The verification of the created computational model has been performed using the example of a normal Glow Discharge between flat electrodes. Results of numerical simulation are presented of normal Glow Discharge between electrodes in the form of spherical segments at pressure p = 5Torr and emf of power supply in the region of 1000 ÷ 1750 V.

normal Glow Discharge in axial magnetic field
Plasma Sources Science and Technology, 2014Co-Authors: Sergey Surzhikov, J ShangAbstract:Theory and results of mathematical modeling of a Glow Discharge in a parallel-plate configuration with axial magnetic field is presented. The model consists of continuity equations for electron and ion fluids, the Poisson equation for the self-consistent electric field. Numerical simulation results are presented for two-dimensional Glow Discharge at various initial conditions. The results are obtained for molecular nitrogen at pressure 1–5 Torr, emf of power supply 1–2 kV, and magnetic field induction B = 0–0.5 T.It is shown that in the presence of the axial magnetic field the Glow Discharge is rotated around its axis of symmetry. Nevertheless it is shown that in the investigated range of Discharge parameters in an axial magnetic field the law of the normal current density is retained.

Ion nitriding of titanium alloys in low-pressure Glow Discharge
2016 27th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV), 2016Co-Authors: V. V. Budilov, Kamil N Ramazanov, I. V. ZolotovAbstract:The samples of VT-6 and VT-3-1 titanium alloys were nitrided in Glow Discharge with hollow cathode and by conventional ion nitriding. Microhardness profiles and microstructure photos were obtained; wear tests and X-ray analysis were performed. From analysis of obtained data revealed that the ion nitriding in Glow Discharge with hollow cathode leads to surface mechanical characteristics improvement. Therefore, it is an effective way to better the operational properties of titanium alloys parts.

Metal Science and Heat Treatment, 2007Co-Authors: V. V. Budilov, Rashid Agzamov, Kamil N RamazanovAbstract:The process of ion nitriding in the plasma of Glow Discharge under the conditions of occurrence of hollow cathode effect (HCE) is studied. The action of the HCE on the parameters of the Glow Discharge and on the structure and distribution of microhardness over the thickness of nitrided layers on steel 38KhMYuA and on titanium alloy VT22 is determined. Nitriding in Glow Discharge without HCE is performed for comparison.
