Abstract Scope Chloride salts have been identified as one of the promising media for thermal energy storage and heat transfer for achieving higher operating temperatures. However, these molten salts introduce a set of challenges. LM Group Holdings, Inc. has developed and applied proprietary innovative amorphous-based coatings that are able to withstand the severe corrosive environment of molten salt at high temperatures. Amorphous metals are a novel class of materials that have a disordered, non-crystalline, glassy structure. Amorphous Metals are more corrosion resistant compared to conventional metals due to the lack of long-range periodicity, related grain boundaries and crystal defects such as dislocations. This presentation will highlight amorphous thermal sprayed coatings on Haynes 230 which have been tested at ORNL and SRNL and compared to non-coated Haynes230 in terms of corrosion resistance under molten chloride salt at 750 degree C.
