The experimental work reported here is devoted to the study of the luminous activity of a long dielectric barrier discharge (DBD) afterglow at atmospheric pressure. The discharge plasma is generated in a commercially available (AcXys Technologies) reactor, using a N2 flow of a few tens SL/min, whereas the luminous afterglow when channelled into a quartz tube extends at a distance of 50 cm, finishing in a luminous arrow at the tube's exit. The luminous activity of the afterglow is studied by means of photomultiplier scans and optical emission spectroscopy, revealing an interesting transient phase. An attempt is made to correlate this effect with the active species' creation and destruction mechanisms. 展开更多

The experimental work reported here is devoted to the study of the modifications inflicted on the surface of titanium alloy specimens by an atmospheric pressure dielectric barrier discharge(DBD) reactor in both spatial and temporal afterglow conditions. A commercially available (AcXys Technologies) modified reactor system was used for the surface treatment of the TiA6V4 titanium alloy that is widely used in the aeronautical industry. Wettability surface characterisation and XPS analyses are performed to give a macroscopic and microscopic insight to the surface modifications. Best operating conditions, at constant input energy, were obtained for a duty cycle equal to 10%. 展开更多
