In this present paper, an experimental study of some plasma characteristics in dielectric barrier discharge (DBD) system using several variables, such as different frequencies and using two different electrodes metals(aluminium (Al) and copper (Cu)), is represented. The discharge plasma was produced by an AC power supply source of 6 and 7 kHz frequencies for the nitrogen gas spectrum and for two different electrodes metals(Al and Cu). Optical emission spectrometer was used to study plasma properties (such as electron temperature ( ), electron number density ( ), Debye length ( ), and plasma frequency ( )). In addition, images were analysed for the plasma emission intensity at atmospheric air pressure.

“…This behavior may be explained as, the presence of magnetic field causes to increase the plasma confinement and this will increase the electron inelastic collision with argon atoms and causes to decrease the electron temperature. This is due to the characteristics of hollow cathode at the low pressures to produce more energetic excitation [9]. Fig.…”

Experimental study on the effect of cylindrical hollow cathode, working pressure and magnetic field on spatial glow distribution and the characteristics of plasma produced by dc discharge in Argon gas, were investigated by image analyses for the plume within the plasma. It was found that the emission intensity appears as a periodic structure with many peaks appeared between the electrodes. Increasing the pressure leads to increase the number of intensity peaks finally converted to continuous form at high pressure, especially with applied of magnetic field, i.e. the plasma is more stable with the presence of magnetic field. The emission intensity study of plasma showed that the intensity has a maximum value at 1.07 mbar pressure and decrease with more pressure.

“…The main application of glow discharge is to use its luminous effect, such as neon lamp and fluorescent lamp [12][13][14][15] . Glow discharge is also used in composition analysis of material surface peeling, surface purification, sewage treatment, sterilization and disinfection, ion source of analytical instruments, plasma nitriding, double glow surface alloying, etc [16][17][18][19][20][21] .…”

In order to break the limitation of plasma nitriding technology, which can be applied to a few non-metallic gaseous elements, the "Double Glow Discharge Phenomenon" was found and then invented the "Double Glow Plasma Surface Metallurgy Technology". This double glow plasma surface metallurgy technology can use any element in the periodic table of chemical elements for surface alloying of metal materials. Countless surface alloys with special physical and chemical properties have been produced on the surfaces of conductive materials.By using double glow discharge phenomenon, a series of new plasma technologies，such as the double glow plasma grapheme technology, double glow plasma brazing technology, double glow plasma sintering technology, double glow plasma nanotechnology, double glow plasma cleaning technology, double glow plasma carburizing without hydrogen and so on, have been invented.A very simple phenomenon of double glow discharge can generate about 10 plasma innovation technologies, which fully shows that there is still a lot of innovation space on the basis of classical physics. This paper briefly introduces the basic principles, functions and characteristics of each technology. The application prospects and development directions of plasma in metal materials and machinery manufacturing industry will also be discussed.
