“…Cold plasma technology has been recently researched and its potentials validated, through functional prototypes, for a wide set of industrial applications including innovative refrigeration systems 1 – 3 , bacterial inactivation processes 4 – 7 , surface treatment procedures and many others 8 – 10 . There are several configurations 7 , 11 , 12 that have been studied for the creation of related devices, capable of applying cold plasma to different industrial fields, from robotics to medical devices, from drones to space appliances. However, most available demonstrators are still in a prototype stage and little attention has been paid to long-term reliability, which is fundamental for increased safety, better operational stability, extended useful life and overall industrial and commercial success.…”

Atmospheric corona discharge devices are being studied as innovative systems for cooling, sterilization, and propulsion, in several industrial fields, from robotics to medical devices, from drones to space applications. However, their industrial scale implementation still requires additional understanding of several complex phenomena, such as corrosion, degradation, and fatigue behaviour, which may affect final system performance. This study focuses on the corrosive behaviour of wires that perform as a high-voltage electrode subject to DC positive corona discharge in atmospheric air. The experiments demonstrate that the non-thermal plasma process promotes the growth of the oxidative films and modifies the physicochemical properties of the materials chosen as corona electrodes, hence affecting device operation. Surfaces exposed to this non-thermal plasma are electrically characterized by negative exponential decay of time-depend power and analysed with SEM. Implications on performance are analysed and discussed.

“…Historically, experiments have generally followed the form suggested by the classical Townsend law for the current-voltage characteristic. However, it should be noted that others have suggested alternative relationships given in [30][31][32][33]. The mathematical processing of the experimental data and the application of the updated knowledge of the corona threshold has allowed to modify the Townsend law as described by Meng et al A new general formula in characterizing the relationship of the corona currentvoltage was derived and expressed as…”

In the present work an experimental investigation has been carried out on the influence of the air humidity or the water vapor injected in the incoming air flow on DC corona discharge parameters in a wire-to-planes electrostatic precipitators. To characterize the behavior of the corona discharge for both positive and negative corona, the current-voltage characteristics are subjected to an analysis using the model of Cooperman which derives the quadratic Townsend law and the general formula proposed by Meng et al. The experimental results show that the discharge current is strongly influenced by the level of air humidity. Moreover, the corona current becomes very small with the applied voltage beyond Hr = 90%, because the particle size is increased by condensation. It was demonstrated that the Coopeman model is reliable to determine the mobility of the charge carriers in this system.
