This article describes a plasma-generating system based on non-self-sustained glow discharge with external electron injection and hollow cathode in the shape of tube an internal diameter 25 mm length 300 made stainless steel AISI 321. It is proved that parameters under (0.2-1) Pa, (100-280) V, (2-6) A depend auxiliary current to great extent, which due determining influence electrons injected from plasma physical processes main discharge. The study uniformity temperature distribution walls...
The article presents the results of studying influence parameters a glow discharge in non-self-sustaining mode on degree inhomogeneity generated plasma inside an elongated hollow cathode with length 300 mm and inner diameter cavity 25 mm, at voltage up to 250 V pressure 1 Pa.
Abstract This paper presents the results of a study an electron-ion-plasma alitization system using two arc plasma generators: gas generator based on non-self-sustained discharge with thermionic cathode “PINK” and gas-metal spot. The for discharges supplying biasing samples assumes sub-modes operation: ion cleaning sub-mode (ion sub-mode) electron heating (electron sub-mode), thus realizing “elion” mode operation. During experiments, both dependences average values currents voltages burning...
The paper presents a system which comprises gas plasma source and an ion allows surface treatment of dielectrics due to charge compensation by electrons. energy corresponds the discharge voltage source. hardness a-C:H coatings deposited method is up 40–45 GPa.
The paper reports on a study of A7 aluminum alloy exposed to thermochemical treatment with nitrogen ion beam produced in source based non-self-sustained hollow-cathode glow discharge. material was placed plasma generated by thermionic and hollow cathodes simultaneously treated accelerated ions neutrals the working gas. No negative bias used, allowing dielectric surface no cathode spots. charge at compensated electrons from plasma. specimen temperature maintained independent energy current...
Представлены результаты азотирования стали 40Х.Генерация плазмы осуществлялась с помощью источника на основе несамостоятельного дугового разряда накаленным и полым катодами.Исследовано влияние температуры образцов характеристики ионно-модифицированного слоя.Температура выбиралась в пределах от 450 °С до 650 путем изменения коэффициента заполнения импульса смещения средней плотности ионного тока.Показано, что микротвердость после увеличивается практически 2 раза (с 3.6 ГПа 7
Разработан метод обработки внутренних полостей протяжѐнных изделий криволинейной формы.Для генерации плазмы при низком давлении (0.5-1 Па) использовалась двухступенчатая система, где основной несамостоятельный тлеющий разряд с полым катодом генерировал рабочую плазму в обрабатываемой полости, а плазма вспомогательного разряда, создаваемая плазмогенератором «ПИНК», являлась источником электронов для стабильного зажигания и горения основного разряда.В данной системе были исследованы основные...
The parameters of the plasma a non-self-sustaining glow discharge generated inside metal hollow cathode 300 mm long and 25 in inner diameter are investigated. A feature this system is additional injection electrons from auxiliary plasma, formed by source with combined heated «PINK». dependences combustion modes presented described at pressure range (0.06 ÷ 1.4) Pa voltage (70 300) V. Studies using double Langmuir probes have shown that provides generation nitrogen inhomogeneity ± 12 to 63%.
