| Abstract Scope |
The cold spray technology has been used as a solid-state additive manufacturing approach to fabricate oxide dispersion strengthened (ODS) steel nuclear reactor fuel cladding tubes as an alternative of the conventional multi-step powder extrusion and annealing process. The research has involved parametric investigations of cold spray process including type of propellent gas, gas pre-heat temperature, powder size distribution and composition, as well as post-deposition thermal treatments to achieve high quality ODS steel material. Both SEM and TEM results showing the microstructure of the cold spray produced cladding tube, as well as radiation response and mechanical properties of these ODS steel tubes will be presented. Finally, results of solid-state cold spray deposition of corrosion and wear-resistant coatings on these ODS cladding tubes for the harsh environments of a nuclear reactor will be presented. |
