Alumina tiles within aluminum framing jigs are fixedly positioned by lock ns within an internally coated mold for centrifugal casting within a block of an aluminum alloy material. Such jigs and the tiles framed therein are coated with silver before casting to prevent aluminum oxidation by heating of the aluminum material to a molten state for deposit into the mold. Bonding of the tiles and framing of the jigs with the aluminum material being cast is also enhanced by such silver coating.

Fabrication of tile reinforced composite armor casting

The article is produced by prepositioning nonwoven reinforcement, coated h a bond enhancing compound inside of a centrifugal casting mold that is surface coated for protective shielding of the reinforcement. Molten matrix metal is then introduced into the mold while being rotated about its longitudinal axis until the molten metal completely encapsulates the reinforcement.
