An imaging spectrograph equipped with a CCD detector was employed to measure two-dimensional emission images from a glow discharge plasma in atomic emission spectrometry. The emission images at Zn I 334.50 nm for a zinc sample and at Cu I 324.75 nm for a copper sample could be obtained. Their emission intensities were not uniform in the radial direction of the plasma region but became weaker at...

The [O] [H] functionalization of carbon nanotube (CNT) was studied using oxygen–hydrogen (O2–H2) gas mixture direct current (DC) glow discharge plasma technique for cathode/CNT-anode separation of 0.10 ± 0.01 cm. O2 and H2 were fixed at flowrate of 10.0 ml/min in order to obtain gas mixture ratio of 1:1. During the (O2–H2) gas mixture DC glow discharge, current–voltage (I–V) characteristic of g...

A theory has been developed that explains the structure formation in a thin surface layer of material after low-energy exposure to glow discharge plasma. This makes it possible design new methods, technologies and automated devices for development an technological environment strengthening various types tools from materials. Based on theory, self-learning system with developing database was cre...

Plasma Surface Metallurgy /Alloying is a kind of surface metallurgy/alloying to employ low temperature plasma produced by glow discharge diffuse alloying elements into the substrate material form an alloy layer. It different with ion nitriding technology, which only applicable infiltration non-metallic elements. “Double Glow Technology”, also known as “Xu-Tec Process” can utilize any chemical i...

Two–dimensional capacitively coupled radio frequency discharge in methane is simulated by PIC-MCC method. The results were obtained in pressure range 50-300 mTorr and voltage range 40-180 V for discharge frequency 13.56 MHz. The electron energy and electron– methane reaction rates spatial distributions show existence of two regimes of discharge glow: a) with active sheaths, when electrons are h...
