ABSTRACT:
A ceramic and metal bonded composite comprising an intermediate metal plate interposed between a ceramic member and a metal member and brazed thereto, the intermediate metal plates carries on its juncture surface a central square projection having substantial area, pins arranged near the four corners and fins between the corners, the central square projection mechanically and thermally couples the ceramic member and the metal member together with the brazing layer and the pins and fins also mechanically and thermally couple the both members together with the brazing layer, while permitting relative displacement between the both members through their plastic deformation, thereby preventing crack generation in the ceramic member.
