Abstract Scope |
The micro cold spray (MCS) process utilizes high velocity impact of solid sub-micron ceramic particles for direct writing of patterned, high quality, thick films at room temperature. Compared to cold spray, which is primarily used for metals and composites, MCS allows for lower operating pressures, smaller particles, finer feature sizes, and the deposition of ceramics. Zinc oxide (ZnO) powder with a size distribution of 10 - 30 nm was deposited using a custom MCS machine equipped with a long converging-diverging nozzle, with impact velocity being altered by means of carrier gas type and the upstream (~1 atm) and downstream (~few torr) gas pressures. Produced films were characterized by SEM imaging and EDS analysis. |
