| 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 only begun to be explored in molten salt for nuclear applications. This study works to further investigate the feasibility of using a laser ablation technique on aluminum samples to decrease corrosion susceptibility, 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), as well as topography and elemental analysis, to quantify passivation layer formation and deterioration. Preliminary results suggest a lack of fully formed passivation layer, however ablation as a method for formation of longer-lasting porous passivation layers appears viable in terms of corrosion rate decrease. Detailed results will be presented and discussed. |
