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