“…In this research, the main objective is to analyze the erosion generated during the ionization process and, consequently, improve the reliability of an industrial electrohydrodynamic (EHD) cooling system. The system corresponds to the “TRAID” arrangement, presented in previous studies by our team 3 , 29 . Present study focuses on systematically evaluating the use of diverse wires as corona electrodes for Direct Current (DC) positive corona discharge in atmospheric air and takes into consideration different diameters and materials.…”

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.

“…Figure 4 demonstrates the point-to-plane corona discharge general configuration. However, the most popular corona discharge configurations in industrial applications are the wire-to-cylinder, wire-to-plane, and saw-to-blade [ 27 ]. The reasons for that are the homogeneous distribution of plasma discharges, and the ease of implementation.…”

Atmospheric Pressure Plasma Surface Treatment of Polymers and Influence on Cell Cultivation

2021

Atmospheric plasma treatment is an effective and economical surface treatment technique. The main advantage of this technique is that the bulk properties of the material remain unchanged while the surface properties and biocompatibility are enhanced. Polymers are used in many biomedical applications; such as implants, because of their variable bulk properties. On the other hand, their surface properties are inadequate which demands certain surface treatments including atmospheric pressure plasma treatment. In biomedical applications, surface treatment is important to promote good cell adhesion, proliferation, and growth. This article aim is to give an overview of different atmospheric pressure plasma treatments of polymer surface, and their influence on cell-material interaction with different cell lines.
