摘要 |
The invention provides an improved combined body of ceramics and metal which maintains high anti-torsional strength and anti-slip off strength while stress concentration is relaxed and deterioration of the ceramics is well prevented. The combined body includes a ceramic member inserted into and firmly engaged with a recess or an opening of a metal member. The combined body has a treated surface region in the vicinity of an engagement end of a contact surface of either the ceramic member or the metal member, and an untreated surface region at a location other than the vicinity of the engagement end.
