The focus of this thesis is to explore the effects of powder characteristics on the cold sprayability of mixed 316L and Fe powders. X-ray diffraction (XRD), electron backscatter diffraction (EBSD) were performed to characterize the feedstock powders before and after mixing. In addition to deposition efficiency (DE), porosity, microhardness and bond strength of the coatings were measured and used as metrics for cold sprayability. Experiments were also performed with a dual powder feeder, which therefore eliminated the need for premixing powders, and introduced new factors which added to the understanding of cold spraying of mixed powder feedstocks. Individual particle impact tests were performed to study the different cold spray behaviors of different particlesubstrate combinations, e.g. Fe on 316L, Fe on Fe, etc., since these events could take place in mixed powders cold spray.
