Ceramic-metal composites offer the promise of improved fracture toughness over that of the ceramic alone. In addition, a continuous ceramic phase should significantly improve the high temperature deformation resistance of the metal. An alumina-copper composite was chosen as a model material. Porous alumina with variable porosity and pore size is prepared by sintering Al2O3 in an HC1 atmosphere to enhance vapor transport and control the microstructure. Molten copper containing dissolved Cu2O for improved wettability is infiltrated into the porous alumina. This results in a 3-dimensional interpenetrating composite of Al2O3 and Cu. The process leads to near-net-shape parts with improved mechanical properties.
