Abstract
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.
