Abstract

A particulate for an additive manufacturing technique includes metallic particulate bodies with exterior surfaces bearing a polymeric coating. The polymeric coating is conformally disposed over the exterior surface that prevents the underlying metallic body from oxidation upon exposure to the ambient environment by isolating the metallic particulate bodies from the ambient environment. Feedstock materials for additive manufacturing techniques, and methods of making such feedstock, are also disclosed.
