| Abstract | An internationally recognized best practice for the permanent disposal of used nuclear fuel is to store them in specially designed containers in a deep geological repository. Copper, as an excellent corrosion-resistant material, has been applied to a carbon steel canister by the means of cold spray (CS) coating in the Canadian design of the used fuel container. In order to provide a basis for future optimization and process control, we experimentally studied the impact of various factors on ductility of the CS copper coatings. The current investigation shows that there can be significant variability in ductility when the feedstock powder properties (e.g., chemical composition and particle size) are changed while keeping the spray and heat treatment conditions constant. Testing results show that the nitrogen-cold sprayed copper coatings’ ductility decreases with increasing hardness in a linear relationship, and can be improved with annealing temperature rising from 300°C to 600°C. The effects of substrate geometry and the variability of the process are also discussed. |
