Plasma aerodynamic excitation based on surface dielectric discharge is a effective approach for flow control, which can significantly improve the aerodynamic characteristics of the aircraft. However, the plasma excitation interaction region is limited and there are no significant effects by using typical two-electrodes sustained by nanosecond-pulse dielectric barrier discharge, therefore, it is difficult...
Combined with plasma enhanced chemical vapor deposition (PECVD), atmospheric pressure plasma jet (APPJ) can be used for depositing film on polymer surface due to its flexibility and high stability. In this paper, the APPJ is excited by a microsecond-pulse generator, and Hexamethyldisiloxane (HMDSO), working as the reaction precursor, is injected into the APPJ discharge region by the carrier gas (Ar)...
Diffuse discharge can generate large-scale volume discharges at atmospheric pressure1, which could be used in surface modification of metal. In this paper, the feasibility of SiO2-like film deposition on copper surface by atmospheric pressure diffuse discharge is achieved. The diffuse discharge is driven by a microsecond-pulse power supply in a point-to-plate electrode configuration, and HMDSO (the...
Nanosecond-pulse dielectric barrier discharge (DBD) can provide non-thermal plasmas with extremely high energy and high density for achieving complicated physical and chemical reactions in surface treatment of polymers. In this paper, the surfaces of low density polyethylene (LDPE) films are modified by atmospheric-pressure non-thermal plasmas generated by nanosecond-pulse DBD 1, 2. The DBD plasma...
Pulsed power can be used for the generation of low-temperature plasma, and different discharge modes, which has been widely used in the field of surface modification1, 2. In this paper, modification on the copper surface by nanosecond-pulse diffuse discharges with a tube-to-plane gap is conducted in atmospheric air. The characteristics of the diffuse discharges are investigated to determine the modification...
