Abstract
A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.
Claims16
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 majority of said ceramic-rich cermet regions are spaced from one another in said heterogeneous body;
- a majority of said ceramic rich cermet regions in said heterogeneous body are not uniformly distributed in said heterogeneous body.
