MATERIAL MODIFICATION IN GLOW DISCHARGE

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.

Radiation Produced by Glow Discharge in Deuterium

Radiation produced by low-voltage discharge in a gas containing deuterium was measured using a Geiger counter located within the apparatus. This radiation was found to consist of energetic particles that were produced only when the voltage was above a critical value. In addition, the emission was very sensitive to the presence of oxygen in the gas. In the presence of the required conditions, em...

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

Artificial cornea: surface modification of silicone rubber membrane by graft polymerization of pHEMA via glow discharge.

A method for producing various surfaces of silicone rubber membrane (SR) was developed in this study by grafting various amounts of poly(2-hydroxy ethyl methacrylate) (pHEMA) onto SR by plasma-induced grafted polymerization (PIP) as a homobifunctional membrane. The elemental composition and different carbon bindings on the surface of SR were examined by electron spectroscopy for chemical analys...

Active Noise Control Using Glow Discharge

First-day spacecraft failures frequently occur as a result of the loads experienced during launch into orbit. These loads include structural vibrations transmitted at points of structural contact, and structural-acoustic vibrations created by the excitation of the payload fairing cavity. Structural control techniques, using piezoelectric actuators, have previously been studied as cost-effective...
