Formation of a low current surface discharge using a negative corona barrier in argon
Authors
Abstract
We present the results of experimental studies of the barrier negative corona of constant voltage excited by a
metal tip over a metal plane covered by a thin film of polytetrafluoroethylene. It is shown that bright surface
discharges – streamers – form on the dielectric surface as the voltage increases. The change in the surface
properties of PTFE films under the influence of low-current surface discharge plasma initiated by a DC voltage
barrier corona in argon has been studied.
