Abstract Scope |
Laser ablation treatments in other research fields have proven useful in the improvement of corrosion resistance in various materials, but this approach has not been fully explored in molten salt for nuclear applications. This study works to determine the feasibility of using the laser ablation technique on aluminum samples, testing the coupons in a eutectic LiCl-KCl salt at 773 K (simulating a pyroprocessing environment). Data sets were collected to allow electrochemical analysis – 24-hour rounds of open circuit voltage, electrochemical impedance spectroscopy (EIS), and linear sweep voltammetry (LSV) quantify passivation layer formation and deterioration. Detailed results will be presented and discussed. |
