Enhancement of Surface Flashover Voltage of 95 Alumina Porcelain in Vacuum Using Cu2O‐Doped Cr Matrix Composite Coating

Surface flashover of 95‐alumina electrovacuum devices in high‐voltage vacuum environments can lead to electrical breakdown. In this study, Cr‐based composite coatings with varying Cu2O doping levels (3%–9%) were prepared on 95‐alumina substrates via high‐temperature solid‐phase sintering. The results show that, at a Cu...
