The experimental work reported here is devoted to the study of the modificationsinflicted on the surface of titanium alloy specimens by an atmospheric pressure dielectric bar-rier discharge(DBD) reactor in both spatial and temporal afterglow conditions.A commerciallyavailable (AcXys Technologies) modified reactor system was used for the surface treatment ofthe TiA6V4 titanium alloy that is widely used in the aeronautical industry.Wettability surfacecharacterisation and XPS analyses are performed to give a macroscopic and microscopic insightto the surface modifications.Best operating conditions,at constant input energy,were obtainedfor a duty cycle equal to 10%.
