Abstract :
Surface characteristics of Insulator effect its surface flashover performance obviously, appropriate surface treatment can increase the surface flashover voltage. Ion implantation technology is an effective surface modification tool, it can change the roughness, resistivity and adsorbability on the insulator surface. Polytetrafluoroethylene (PTFE) was modified by C ion and nitrogen ion by using a electron cyclotron resonance (ECR) ion source. The surface flashover voltage were measured on the experimental platforms of surface characteristics in vacuum before and after modification, Also the characteristies and microstructure of the implanted layer were studied by using the SEM and XPS and find the influencing factors on surface flashover properties of PTFE modified by ion implantation.
