Continuous Surface Modification of Carbon Fiber with DC Glow Discharge Plasma

Dust particle charging in DC glow discharge plasma

Dust particles charging in a stratified positive column of a low-pressure DC glow discharge was investigated theoretically. The presented model consists of (i) previously developed 1D selfconsistent model for discharge parameters on the tube axis; (ii) ambipolar approximation for radial electric potential distribution and the assumption that the electron energy distribution function in radial d...

Double Langmuir probe measurement of plasma parameters in a dc glow discharge

In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...

Surface Modification of Ag Nano Composites Polymer Membranes by Glow Discharge Plasma

Surface Modification of Titanium Alloys in a Non-Uniform Glow Discharge with Hollow Cathode

The characteristics of the non-uniform glow discharge with the effect of the hollow cathode (EHC), on which the chosen regimes of nitriding the surface of titanium alloy VT6 are considered. Experimental results of the influence of inhomogeneous plasma in a pulsed regime of processing on the structure and microhardness of the treated surface are resulted.

Observations of a structure-forming instability in a dc-glow-discharge dusty plasma.

By adjusting the anode current and axial magnetic strength of a dc-glow-discharge dusty plasma, we have found plasma and dust conditions conducive to dusty plasma structurization, similar to the one discussed theoretically by Morfill and Tsytovich [Plasma Phys. Rep. 26, 682 (2000)]. The structurization instability leads to the formation of a pattern where the dust suspension transforms into alt...
