Aus Metall und Keramik zusammengefügte Körper

摘要

A metal-ceramic composite body is produced by fitting a protruding portion of a ceramic member into a concave portion of an intermediate member and joining the intermediate member to a metallic member. In this case, a difference between the inner diameter in the concave portion of the intermediate member and the outer diameter in the protruding portion of the ceramic member is not less than 0.2% of the outer diameter in the protruding portion when the protruding portion is pulled out from the concave portion.
