Abstract
Amorphous metal-ceramic and microcrystalline metal-ceramic composites are synthesized by solid state reaction-formation methods. These metal-ceramic composites are characterized by a composition that ranges from about 75 to about 99.9 percent ceramic in about 0.1 to about 25 percent amorphous or microcrystalline metal binder phase.
Claims6
An amorphous metal-ceramic composite comprising about 75% to about 99.9% ceramic particles disposed in an amorphous metal matrix, said matrix formed by the solid state diffusion of a metal into the surface region of said ceramic particles to form said amorphous metal matrix.
A process for the synthesis of an amorphous metal-ceramic composite, comprising intimately mixing alloying elements in the presence of ceramic particles and heat-treating this mixture to initiate a solid-state reaction-formation, said reaction-formation yielding a dual-phase microstructure composed of from about 75% to about 99.9% ceramic particles interspersed in an amorphous solid matrix binder.
