Abstract Scope Micro-cold spray is the process of accelerating solid nanoparticles through a nozzle and impacting them at high velocity onto a substrate to deposit nanostructured films. By moving the substrate beneath the fixed nozzle, patterned films of metals and ceramics can be deposited at room temperature without a mask. Experiments conducted with direct axial impact of LiNbO3 nanoparticles results in amorphous films that are limited to thicknesses of 10 Ám because the deposition efficiency decreases with film thickness. Molecular dynamics simulations conducted on other ceramic particles suggest that deposition efficiency may be increased by incorporating a radial component in addition to the axial velocity. Experimentally, films have been deposited at nanoparticle impact angles of up to 60░ from the axial position. Annealing the amorphous films at a temperature of 250˚C results in crystallization of the films. The effect of radial impact velocity of the nanoparticles on film deposition efficiency, microstructure, and film properties will be discussed.
