| Abstract Scope |
Material efficiency in cold spray deposition is largely determined by the composition and subsequent mechanical properties of the feedstock powder. While expanding the use of cold spray within industries such as aerospace, defense, and energy, manufacturers accept significant material losses associated with the low deposition efficiency of otherwise high-performance metal alloys. To reduce costly material losses and increase the economic viability of printing high-cost materials, this work explores opportunities to recover and re-spray powder particles which are not deposited during the cold spray process. A dust collection system was used to collect undeposited powder particles from a cold spray system, followed by characterization of the virgin versus recovered powders to quantify any change. Collected powder was evaluated for post-processing to improve powder characteristics and re-printed to compare deposition quality. Capture of the waste stream promises improvements to the circularity of critical metals among uncertain supply chains. |
