HARDENED CERMETS AND METHOD OF FORMING HARDENED CERMETS

摘要

Prepare hardened cermets by: forming a porous ceramic compact that contains a first, or metal component reactive, ceramic component, and a second, or substantially nonreactive, ceramic component; at least partially filling the pores with a metal component to form a metal-filled ceramic compact; exposing the metal-filled compact to an elevated temperature to form a cermet-hardening component; and cooling the resultant compact to form a hardened cermet. Laminates of hardened cermets having differing ratios of first to second ceramic components can also be formed.
