ABSTRACT:
A method of forming a ceramic-metal composite including steps of providing a body of ceramic material; infiltrating molten metal into open spaces of the body at an elevated pressure; cooling the metal to form a solid composite; and reacting a portion of the metal in the composite at an elevated temperature with an oxidizing gas. A particularly preferred composite is made by infiltrating an alumina body with an aluminum alloy and then oxidizing in air at an elevated temperature. The composite is useful for making armor plate and other products where a combination of high hardness, good strength, and light weight are needed.
