Hydrothermal corrosion behavior of Ti3SiC2 MAX phase at atomic scale under simulated PWR conditions
Source abstract
Abstract
Corrosion-induced Si-layer escape of Ti 3SiC 2 and transformation from Ti 3SiC 2 MAX phase to Ti 3C 2 nanosheets at atomic scale under simulated PWR conditions were directly observed using double C S -corrected STEM, overwriting the conventional opinion that MAX phase corrodes in the form of corresponding parent MX ceramic. Bipyramidal anatase and nanocuboid rutile particles were confirmed to coexist in the corrosion layer by SAED and HRTEM. Long-term hydrothermal corrosion of Ti 3SiC 2 indicated its operational reliability in PWR conditions simulated by increasing dissolved oxygen content to accelerate corrosion. This work proposes a reference for the application of Ti 3SiC 2 in PWR fuel cladding.
