METAL-CERAMIC COMPOSITE BODIES AND A METHOD FOR MANUFACTURING THE SAME Abstract of the Disclosure Metal-ceramic composite bodies are disclosed which each comprise a metallic member and a ceramic member. The metallic member is integrally connected to the ceramic member by fitting the ceramic member itself or a projection formed on the ceramic member into a recess or a through hole formed in the metallic member. The hardness of a metallic portion of 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 µm at the maximum height (Rmax) or not more than 0.5 µm at the center line average roughness (Ra). A process for manufacturing the same is also disclosed.
