<p>Methods for sealing an interface surface of ceramic materials (42), such as zirconia, to an interface of metallic materials (40), such as titanium-containing materials, using a titanium-nickel brazes (46) are disclosed. Preferred ceramic include stabilized zirconia materials; preferred metallic include titanium-niobium alloys; and a preferred titanium-nickel braze material is a 50-50 titanium-nickel alloy. Braze materials comprising titanium, nickel, and niobium are used for joining ceramic materials to metallic materials lacking niobium. At least one of the interfaces is contacted by the titanium-nickel braze and sealing is accomplished under vacuum conditions at temperatures from 900 to 1200 °C during application of pressure to the joint. The methods are suitable in hermetically sealing applications in implantable medical devices, electrical connectors, electronic packages, sporting goods, structural components.</p> |
