Document Type and Number:
Japanese Patent JPH0526611
Kind Code:
B2
Abstract:
A metal-ceramic composite body has a metallic member (l) and a ceramic member (3). The metallic member is integrally connected to the ceramic member by fitting the ceramic member itself or a projection (4) formed on the ceramic member into a recess (2) or a through hole formed in the metallic member. To achieve high fatigue fracture resistance and high joining force, the hardness of a metallic portion (A) including at least a fitted portion between the metallic member and the ceramic member is not less than HRC 38. The roughness of the inner surface of the faces of the through hole of the metallic member at the fitted portion is not more than 8 mu m at the maximum height (Rmax) or not more than 0.5 mu m at the center line average roughness (Ra).
