Metallography of Kovar/glass/thermite interfaces
Abstract
Kovar pins are used to form electrical feedthroughs in thermite composites. The pins are electrically insulated from the thermite by a glass coating that bonds the pins to the thermite during processing. Metallography of the glass Kovar interface and the glass thermite interface shows good interfacial contact free of voids and cracks.
