Abstract
A durable ceramic and metallic coating has been applied to ceramic tiles to protect the tiles while undergoing a molten metal casting operation. The plasma sprayed coating consists of a ceramic top coat layer of aluminum oxide, zirconium oxide, or other oxides with or without a metallic bond coat layer and with or without a functionally gradient coating. This coating protects the underlying ceramic tile, which is composed of boron carbide, silicon carbide, alumina (AlO) or other type of hard ceramic, from reacting chemically with the molten metal. The molten metal is cast around the ceramic tiles to create a lattice of ceramic tiles that are used for protection from projectiles and shrapnel.
