Metal-ceramic joined composite bodies and joining process therefor

Abstract From the Canadian patent

Metal-ceramic joined composite bodies each comprise a metallic member and a ceramic member integrally joined together by joining a projection of the ceramic member to a recess of the metallic member. Their joining strength is improved by appropriately selecting joining site and way between the metallic and ceramic members, and/or shapes thereof e.g. by, substantially limiting brazing metal-joining to an interface between the outer peripheral surface of the projection of the ceramic member and the inner peripheral surface of the recess of the metallic member. The joining strength is also improved by forming a groove around the substantially entire outer periphery of the metallic member …
