| Abstract Scope |
High costs, limited supply chains, and long lead times associated with titanium feedstock powders have hindered the widespread adoption of additive manufacturing technologies, such as cold spray, to produce titanium components. This study investigates the potential of using on-demand recycled titanium feedstock powder as a cost-effective, sustainable alternative to virgin titanium powders for cold spray applications. Three unique grades of recycled titanium powders were gas atomized from different battlefield scrap sources using a mobile foundry system developed by MolyWorks Materials Corporation. Recycled titanium cold spray coatings and additive manufactured deposits were compared against virgin Ti-6Al-4V consolidations to verify microstructure and mechanical properties. Findings indicate that recycled titanium powders can produce cold spray deposits with comparable composition, microstructure, and hardness characteristics to those made from virgin materials. This offers potential cost savings, sustainability, and expeditionary benefits for manufacturing/repair purposes, suggesting recycled titanium powders are a viable alternative in cold spray applications. |
