ABSTRACT:
A cermet armor material for highly effective ballistic performance which is comprised of a layer of base metal in which is deposited a layer or layers of ceramic and a compatible metal such that the deposited metal in combination with the base metal forms a continuous matrix around the ceramic particles. The body has a structure which is continuously graded from a highest ceramic content at the outer surface (strike face) decreasing to zero within the base substrate, and contained no abrupt interfaces.
