| Abstract Scope |
The micro cold spray (MCS) process utilizes high velocity impact of sub-micron ceramic particles to deposit thick films at room temperature. Although films from many ceramics have been successfully deposited, the mechanisms responsible for the sticking of particles upon impact remain poorly understood. In this study, the impact of wurtzite zinc oxide (ZnO) nanoparticles onto a zinc oxide substrate was studied as a function of particle diameter (size range) and particle impact velocity (velocity range) to determine the deformation mechanisms responsible for adhesion and film formation. Molecular dynamics (MD) simulations were conducted in the LAMMPS software package. Zinc oxide films were also produced experimentally using MCS and characterized to compare with the results from MD simulations. |
