Abstract

AbstractCorrosion behavior of (Cr2/3Ti1/3)3AlC2 and Ti3AlC2 in static oxygen‐saturated liquid lead–bismuth eutectic (LBE) at 550°C and (Cr2/3Ti1/3)3AlC2 in static oxygen‐depleted LBE at 500°C were investigated. In oxygen‐saturated corrosion, the loose and porous corrosion layer consisting of (PbTiO3 + TiO2) was generated on the surface of Ti3AlC2. In contrast, (Cr2/3Ti1/3)3AlC2 formed the protective Cr2O3 layer with better corrosion resistance. Moreover, dissolution corrosion of (Cr2/3Ti1/3)3AlC2 in oxygen‐depleted corrosion was intensified without a protective oxide film. And impurity phase TiC on the surface also caused the decomposition of matrix, thus impairing corrosion resistance.
