Abstract Scope |
Bimetallic structure consisting of a corrosion resistant surface layer joined on top of ASME code approved nuclear reactor structural materials has become a promising solution to address the corrosion issue in molten salt reactors. This DOE-funded work aims to develop cold spray enabled bimetallic structures with a refractory-based coating on ASME code-certified substrate. ICME was employed to design novel alloy compositions that combine improved cold spray processability with high molten salt corrosion resistance and strong interfacial bonding. Initial cold spray trials depositing these compositions on 316 stainless steel were successfully performed. Coatings were proved to be of high quality by metallographic inspection and have strong adhesion by adhesion testing. Molten salt test protocols have been developed. Cold spray materials have been tested and characterized post-test. Observations indicated are that all the alloy compositions were promising in terms of corrosion resisting performance after 750°C for 100 hours in molten chloride salt. |
