| Abstract Scope |
Cold spray additive manufacturing is a solid-state deposition process in which metal feedstock powder is accelerated to supersonic velocities and impacted onto a substrate. Feedstock powders often benefit from annealing to enhance ductility, thereby improving particle deformation, interlayer cohesion, and deposition efficiency. However, absorption of oxygen, nitrogen, or hydrogen during this process can lead to undesirable brittle properties, and maintaining a heat-treating environment with minimal oxygen is difficult with vacuum pumps or inert gas alone. This project introduces a reactive titanium foam getter system to sacrificially absorb oxygen during heat treatment of copper powders manufactured for cold spray. The getter system effectively minimized oxygen absorption in the feedstock powders and removed nearly all moisture from the samples. |
