Kinetics of Plasma Chemical Reactions Producing Nitrogen Atoms in the Glow Discharge in a Nitrogen–Argon Gas Mixture

Abstract

The problem of determining the content of nitrogen atoms in the low-pressure glow discharge (GD) plasma in a nitrogen–argon gas mixture has been considered. The balance of the nitrogen atomic concentration includes for the generation of nitrogen atoms in the course of the molecular nitrogen dissociation by the electron impact, the interaction of nitrogen molecules with metastable Ar, and the loss of nitrogen atoms in the diffusion process followed by the heterogeneous recombination at a GD cathode. The influence of the gas mixture composition on the atomic nitrogen generation is determined by numerical calculations, whereas the plasma parameters are found experimentally using the probe method. The electron energy distribution is determined by numerically integrating the Boltzmann equation written in the binomial approximation for a mixture of molecular nitrogen and argon.

Розглянуто задачу визначення вмiсту атомарного азоту як активної компоненти, вiдповiдальної за ефективнiсть технологiй модифiкацiї поверхнi металiв у плазмi стацiонарного жеврiючого розряду (ЖР) низького тиску в сумiшi азот–аргон, широко застосовуванiй у цих технологiях. Баланс концентрацiї атомiв азоту включає їхню генерацiю дисоцiацiєю прямим електронним ударом молекулярного азоту та взаємодiєю останнього з аргоном у метастабiльних станах i втрати у дифузiйних процесах з подальшою гетерогенною рекомбiнацiєю на катодi ЖР. Вплив складу сумiшi на продукування атомарного азоту визначався розрахунковим шляхом, а параметри плазми – експериментально, зондовим методом. Функцiя розподiлу електронiв за енергiями визначалась чисельним iнтегруванням рiвняння Больцмана, записаного в двочленному наближеннi для сумiшi молекулярного азоту й аргону.
