  • Methods and systems for ballistic manufacturing of micro/nano coatings and artifacts
    Patent number: 10823541
    Abstract: Provided herein are systems and methods for applying materials to articles or projectiles in order to coat at least a portion of the projectile. An embodiment of disclosure provides launching the a projectile into a stream of fluid. The fluid may be a molten metal, powder suspension or slip to be later sintered, molten polymer, monomers to be later polymerized or gaseous species that can locally react with the projectile to produce coatings such as oxides, nitrides, carbides, etc. The passage of the projectile through the fluid results in a coating on the projectile.
