A metal ceramics composite article and a process for manufacturing the same.

摘要

A metal-ceramic composite article comprising a metallic member 2 made of a precipitation hardening alloy and a ceramic member 1, wherein a projection 4 formed on the ceramic member is fitted into a hole 3 or a through hole formed in the metallic member. To achieve tight fitting of the projection 4 in the hole 3, the metallic member of the composite article is hardened by precipitation hardening, and preferably also nitriding, after fitting. The alloy may be one which shrinks on precipitation hardening. The projection may be fitted in the hole fitted by press fitting, shrinkage fitting or expansion fitting.
