Abstract
An article includes a ceramic member (5) and a composite member (9) bonded together. The composite member is formed of a substrate member and a deformable metal layer which is mechanically fixed to the substrate member. The substrate member is formed of a material which is harder than the deformable metal. The ceramic member and the deformable metal layer of the composite member are hermetically sealed together by a solid phase bond formed by ultrasonic welding.
