1. A heterogeneous body comprised of a plurality of ceramic-metallic composites; each of said ceramic-metallic composites includes a ceramic-rich cermet region coated with a metal coating about an outer surface of said ceramic-rich cermet region; said ceramic-rich cermet region comprises a plurality of ceramic particles that are bonded together by a metallic binder; a majority of said ceramic-rich cermet regions remain intact and are spaced from one another in a metal matrix material; a plurality of said ceramic-rich cermet regions are spaced from one another in said heterogeneous body; a plurality of said ceramic-rich cermet regions in said heterogeneous body are not uniformly distributed in said heterogeneous body; a content of metal in said metal coating greater than a content of metal of said metallic binder.
