Abstract :
The influence of thin (0.15 μm) dielectric films TiO2, coating by anodization, on the pulsed electric strength of vacuum gaps with titanium electrodes was investigated. As a benchmark for comparison was the value of ~ 1.6 MV/cm of electric strength of the vacuum gap with titanium electrodes after pulsed melting of the surface by electron beam. We also give results on the measurement of electrical strength of vacuum gap after complex treatment of electrodes (surface remelting followed by coating of the oxide).
