This study focuses on cold-spray deposition of polystyrene particles on polymeric and aluminum substrates. A number of different process conditions were investigated to achieve buildup of particles on the substrates. Analysis was performed to characterize the deposition thickness on each substrate. Promising results were obtained with polymeric substrates when the gas temperature and substrate heating was kept around the glass-transition temperature of the particle. As shown in figure, with 10 passes, 15 Î¼m deposition was obtained at these conditions. The deposition on the aluminum substrates is still an ongoing investigation that is mainly focused on the first-layer adhesion, since the first couple of layers of deposited particles plays a key role during the process.
