| Abstract Scope |
Cold spray has emerged as a versatile solid-state manufacturing technique with significant potential for nuclear applications. This work explores its dual functionality as both a coating method for plasma-facing components (PFCs) and an additive manufacturing route for oxide dispersion-strengthened (ODS) steel cladding tubes in nuclear reactors. PFCs undergo extreme thermal loads and irradiation damage. The key challenge in traditional PFC fabrication is bonding them to heat sinks without degrading the performance of either material. This study explores cold spray for depositing ultra-high-temperature ceramic (UHTC) coatings while avoiding the high temperatures associated with conventional methods.
In parallel, conventional fabrication of ODS steels often leads to challenges in maintaining nanoscale oxide dispersion. This work examines cold spray as a promising method for additively manufacturing ODS steel tubes while retaining fine microstructural features. Overall, this work highlights cold spray as a unified and scalable solution for next-generation nuclear materials. |
