Abstract Scope |
The understanding of corrosion mechanisms and kinetics in chloride salts is a limiting factor to the deployment of MSR’s. Especially, variations in the salt chemistry have been shown to have a significant impact on the corrosion kinetics of alloys at high temperatures.
This work aims to develop an experimental setup to modify and monitor the moisture content in chloride molten salts. This setup will enable corrosion tests and contribute to a comprehensive understanding of moisture-driven corrosion in these salts.
To that purpose, an electrochemical cell was built to monitor the oxygen anion concentration, introduced by humidified argon bubbling, in both CaCl2 and MgCl2 salts. The calibration of the working electrode was performed using oxide powder.
Static corrosion tests of Ni-20Cr and SS316 have been performed in the chloride molten salt under different controlled moisture environments and correlations between moisture content and corrosion will be discussed. |
