| Abstract Scope |
This study investigates the feasibility of applying stainless steel 316L (SS316L) onto copper substrates using Direct Energy Deposition (DED) for potential use in radioactive waste storage canisters. Copper is considered a promising material for long-term containment due to its corrosion resistance, and SS316L offers additional protection in extreme environments. The DED process, using a 4-way nozzle, was employed to deposit SS316L onto carbon steel as a surrogate for copper. The effects of key process parameters, such as laser power, on the microstructure were examined, revealing changes in grain growth behavior. Mechanical performance was evaluated through three-point bending tests and potentiodynamic polarization tests. Results show that optimized DED parameters can produce coatings with desirable mechanical and corrosion-resistant properties. These findings support the potential of additive manufacturing to enhance the durability and functionality of copper-based storage systems for high-level radioactive waste in demanding environments. |
