In order to technological use in the preparation and application of plasma coatings, the mutual influence of acoustic impact on low-temperature plasma was conducted, the experimental methodology and the results of the study in the pipe at the resonant excitation frequency are given. The nonlinearity of sound oscillations was found and their amplification by increasing the pressure, which can be used to intensify the processes of plasma coatings.

The low-temperature plasma technology has the comprehensive action of high-energy electron, ultraviolet light, ozone etc. The technology that integrates light, electronic and chemical oxidation into one process has a good development prospect in wastewater treatment. In this paper, the research status and development trend of high-voltage pulsed discharge, dielectric barrier discharge, glow discharge for organic wastewater treatment at home and abroad are summarized. The current main existing problems include single treatment object oriented. In the future, the study about this technique should be focused on the optimization process, the reduction of the processing cost and energy consumption, so that this technology can be applied to practical wastewater treatment as soon as possible.Key words: Low temperature plasma technology; High-voltage pulsed discharge; Glow discharge; Dielectric barrier discharge; Wastewater

Our previous work has shown that for cardiac applications, combining low-temperature plasma oxidation with an amorphous carbon coating (a-C:N:H type) constitutes a prospective solution. In this study, a short-term modification by low-temperature oxygen plasma is proposed as an example and a method for shaping the topography and surface energy of the outer amorphous carbon coating, produced via the Radio-Frequency Chemical Vapour Deposition (RFCVD) method on NiTi alloy oxidized under glow-discharge conditions. This treatment alters the chemical composition of the outer zone of the surface layer. A slight increase is also noted in the surface roughness at the nanoscale. The contact angles were shown to increase by about 20% for water and 30% for diiodomethane, while the surface free energy decreased by ca. 11%. The obtained results indicate that even short-term contact with low-temperature plasma can shape the surface properties of the carbon coating, an outcome which shows potential in terms of its use in medical applications.
