Abstract
The paper presents the results of a study of the effect of an oxide film formed on the edge of an electrode on the filamentation threshold voltage of a surface nanosecond DBD. Since the oxidation of the discharge edge has a significant effect on the discharge operation mode and dissipated power, some changes in the filamentation thresholds should be observed. The presented data include the filamentation thresholds of a discharge on an aluminum electrode in synthetic air in the pressure range of 1-10 bar in the case of a new electrode and an electrode covered by an oxide layer. The studies were carried out for both positive and negative polarity of the supply voltage pulse at two pulse shapes with different voltage growth rates. The effect of pulse shape, as well as the effect of air humidity on the filamentation threshold, is discussed.
