| Abstract Scope |
This study investigates the effect of flow-induced dynamics on the corrosion behavior of 316 stainless steel and Hastelloy C276 in a molten eutectic KCl-LiCl salt at 500 °C. A dynamic corrosion test was conducted using a custom-designed rotating system to simulate flow conditions, where samples were continuously rotated in the molten salt for 7 days. This setup replicates convective mass transport typically found in molten salt systems. Post-exposure analyses, including weight loss, SEM, EDS, and XRD, were used to characterize corrosion rates and surface chemistry. Electrochemical corrosion testing under static conditions is also used to establish a baseline for mimicking accelerated corrosion process. Results revealed significantly higher corrosion under dynamic flow, attributed to the disruption of protective oxide layers and enhanced salt-metal interactions. These findings emphasize the critical role of flow in accelerating high-temperature corrosion and provide valuable insights for the development of corrosion-resistant materials for dynamic molten salt environments. |
