N2 - The effect of plasma surface treatment of epoxy resin (EP) AI2O3 micro-composite for different times (1min, 3min and 5min) on vacuum surface flashover performance had been researched in this study. Three critical factors for surface flashover, such as surface chemical composition, surface trap parameters and surface conductivity, had been evaluated through X-ray photoelectron spectroscopy (XPS), surface potential decay (SPD) and Keithley 6517B respectively in order to find out the influence mechanism of plasma treatment. The spectrum of XPS presents that after modification the surface content of O greatly improves with increasing treatment time. SPD results show that shallow trap level decreases first and then increases while shallow trap density increases first and then decreases with the increasing of modification time. DC flashover voltage of samples before and after plasma treatment had been tested in vacuum, the result showed that surface flashover voltage increased first and then decreased with increased processing time, and the highest surface flashover voltage appears at 3min. Surface conductivity increases first and then decreases with the increasing of treatment time too. It can be concluded that plasma treatment can modify surface flashover property of EP Al2O3 micro-composite by altering surface characteristics like trap distribution and surface conductivity.
