Abstract:
1. A method of forming armor, comprising: (a) providing a base material, a heat source, and a metallic feedstock in a gaseous atmosphere; (b) delivering a gaseous alloying element proximate to the metallic feedstock; (c) converging the heat source on the metallic feedstock and the gaseous alloying element; (d) melting the metallic feedstock with the heat source to form a molten pool on the base material, such that the metallic feedstock alloys only with the gaseous alloying element to form a composition on the base material; and (e) cooling and solidifying the composition to form a first layer directly on the base material, the first layer having different mechanical and physical properties than the base material, and the base material is not alloyed with the gaseous alloying element.
