| Abstract Scope |
Metal powder-based additive manufacturing (AM) processes have seen increased use in academia, government, and industry over the past decade. Often, the success of these processes is contingent on the quality of the feedstock powder used. This dependency is even greater for solid-state AM processes such as cold spray (CS). The CS process greatly relies on adequate control of powder flowability and moisture content in order to maintain predictable through-process powder behavior. However, frequently during handling, the metallic powder is repeatedly exposed to ambient conditions, which has the potential to degrade powder properties. To avoid compromising the future success of the CS process, it is critical to understand how this environmental exposure during powder handling can affect the feedstock's properties. It is the aim of this study to evaluate the effects of repeated environmental exposure on the flowability and moisture content of aluminum alloy powders for CS applications. |
