COATED BALLISTIC STRUCTURES

摘要

Armor components having a ceramic substrate, a thermal sprayed barrier coating covering the substrate material to form a barrier coated substrate, and an outermost encapsulation of metal generally surrounding at least the periphery of the barrier coated substrate are disclosed herein. The encapsulation of metal was cast to the ceramic substrate as molten metal, and the thermal sprayed barrier coating comprises a cermet material, a ceramic material, or a combination thereof. The ceramic substrate is preferably a ceramic tile for ballistic armor. Also disclosed are armor components having a plurality of the ceramic tiles interconnected by the encapsulation of metal, with the metal, which was casted thereto, surrounding at least the periphery of each of the plurality of the armor components.

1. An armor component comprising:
a ceramic substrate having a first coefficient of thermal expansion; a thermal sprayed barrier coating covering the substrate material to form a barrier coated substrate; and an outermost encapsulation of metal generally surrounding at least the periphery of the barrier coated substrate; wherein the encapsulation of metal was casted thereon as molten metal having a second coefficient of thermal expansion; wherein the thermal sprayed barrier coating comprises:
a first coating applied to the ceramic substrate and comprising a cermet material, a ceramic material, or a combination thereof having a coefficient of thermal expansion most closely matching the first coefficient of thermal expansion; anda second coating over the first coating, the second coating comprising a metallic material and having a coefficient of thermal expansion most closely matching the second coefficient of thermal expansion.
