## Description

- description: Flash healing is a technique that uses power spikes to rapidly repair
    microcracks on ceramic surfaces. In this study, the microstructures of flash-healed
    Vickers-indented microcracks near the positive/negative electrodes under a DC
    electric field were examined by scanning transmission electron microscopy. The
    microstructural morphology near the positive electrode was almost identical to
    that of the microcracks located between both lectrodes, as previously reported.
    However, a decrease in the degree of healing was observed near the negative electrode.
    This was attributed to the insufficient recovery of dislocations generated at
    the indentation state, which should have occurred in the initial stage of healing.
    The delay in dislocation recovery prevented contact between the inner surfaces
    of the microcracks and is possibly related to the increase in oxygen vacancies
    near the negative electrode.
