## Description

- description: Ceramic bearings possess superior thermal and mechanical properties
    but are prone to crack formation and lubricant degradation at high temperatures,
    driving the development of self-healing ceramics to improve their reliability
    and lifespan. This study investigates the high-temperature self-healing behavior
    of surface cracks in Al2O3-containing vanadium carbide (VC) particles and Al2O3
    pre-incorporated with both SiC and VC particles as healing agents. Bending tests
    show that the required healing time for reaching the strength of 500 MPa in Al2O3
    containing both VC and SiC achieves approximately 1/6000 times shorter than that
    in Al2O3-SiC composites without VC addition and significantly shorter than that
    of VC-added Al2O3. Excessive internal oxidation of pre-incorporated submicron-
    to micron-sized VC induces pore formation, reducing strength and hindering full-strength
    recovery. Formation of a SiO2 protective layer against SiC oxidation mitigates
    pore formation. These findings provide a basis for designing ceramics capable
    of rapid, low-temperature self-healing without pore generation.
