Abstract
A method, in accordance with one embodiment, includes forming an array of structures from a raw material via cold spray. Each of the structures is characterized by having a defined feature size in at least one dimension of less than 100 microns as measured in a plane of deposition of the structure, at least 90% of a theoretical density of the raw material, and essentially the same functional properties as the raw material. A method, in accordance with another embodiment, includes positioning a mask between a cold spray nozzle and a substrate, and forming a structure on the substrate by cold spraying a raw material from the cold spray nozzle. The structure has a shape corresponding to an aperture in the mask.
