Interfacial phenomena in electric field-assisted anodic bonding of Kovar/Al film-glass

摘要

Anodic bonding of glass to Kovar alloy coated with Al film (Glass-Al film/Kovar) was performed in the tem- perature range of 513～713 K under the static electric voltage of 500 V in order to investigate the interfacial phenomena of al-glass joint. The results reveal that Na and K ions within the glass are displaced by the applied field from the anode-side surface of the glass to form depletion layers of them.
