Method of bonding zirconia to platinum
Abstract:
The invention is a method of hermetically bonding a ceramic part to a metal part by welding and brazing a component assembly comprised of metal parts, a ceramic part, and a metal ferrule having alignment lips. The ceramic part is preferably a hollow tube of partially-stabilized zirconia that is brazed to an alignment ferrule that is preferably titanium or a titanium alloy, such as Ti-6Al-4V. On one end the component assembly is brazed to an end cap for closure. On the other end the alignment ferrule is preferably brazed to a ring that is preferably comprised of a noble metal, such as platinum, iridium, or alloys of platinum and iridium. The ring is laser welded to an eyelet that is preferably comprised of a noble metal.
