Although the crack-healing capacity of Ti₂AlC ceramics has been sufficiently studied, the ability of Ti₂AlC to self-heal large-scale damage, such as foreign object damage (FOD), remains unknown. This paper investigates the self-healing ability of Ti₂AlC ceramics with large-scale damage (∼1000 μm in diameter). Extensive healing was observed even in the plastic damage and radial cracks. The damage and cracks caused by indentations made using a tungsten carbide sphere were filled and covered with newly formed oxides, such as titanium oxide and alumina, by the oxidation of Ti₂AlC after heat treatment in air at 1000 °C. The strength, hardness, toughness, and elastic modulus of the Ti₂AlC samples were measured before and after healing. The results show that the mechanical properties of Ti₂AlC were similar or even slightly higher after the damage had been healed. Thus, Ti₂AlC ceramics are attractive healing agents for foreign object damage in high-temperature applications.
