Development of Inexpensive Surface Finishing Process for Transparent Armor

Abstract

73-34(*Armor, *Glazes), (*Surface finishing, Armor), Transparence, Tiles, Sapphire, Glass, Polishes, Optics, Silicates Transparent armor. The objectives of this program were to develop a process for coating rough-ground sapphire tiles with index matching glasses. The cost of finishing the transparent armor tiles can thereby be reduced by polishing with conventional, inexpensive glass polishing procedures rather than those needed for sapphire. These objectives were met using a lead-silicate glass on pretreated sapphire tiles. The optical properties of the coated tiles were essentially those of sapphire. Alternative finishing procedures based on refiring rough-ground, coated tiles and purely chemical polishing were demonstrated. These could lead to even further cost reduction in finishing transparent armor.
