Decelerated lead-bismuth eutectic corrosion of FeCrAlTiMo coating by in situ proton irradiation
Synergistic effect of the simultaneous proton irradiation and lead-bismuth eutectic (LBE) corrosion on the amorphous FeCrAlTiMo coatings was investigated. Results displayed that proton irradiation had a positive effect on LBE corrosion resistance of the coating. The experimental and simulation results demonstrated that irradiation-induced annihilation of the free volume reduced the diffusion kinetic and lead to slower corrosion rate at 600 °C, which challenged the traditional wisdom that irradiation damage resulted in negative effect on materials corrosion. Finally, a novel mechanism of irradiation-decelerated corrosion was proposed, which provided a new approach for designing nuclear-structural materials with better corrosion and irradiation resistance.
