PCT No. PCT/GB90/00999 Sec. 371 Date Dec. 31, 1991 Sec. 102(e) Date Dec. 31, 1991 PCT Filed Jun. 28, 1990 PCT Pub. No. WO91/00255 PCT Pub. Date Jan. 10, 1991.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.
