| Outline of Final Research Achievements |
In this research, nanocomposites with self crack healing ability were synthesized by a hot-pressing method. After performing the crack-healing process by annealing in air, the composites were heat-treated in steam to reobtain the healing agent. The healing agent was partially recycled after a heat treatment in water vapor. A multiple crack-healing test was conducted to investigate the improvement in the healing ability of the composite after the water-vapor treatment. Compared with the composite without treatment, the crack-healing ability of the composite treated in steam was enhanced (3～30%). These results suggest that a water-vapor treatment can help to recycle the healing agent and is hence of importance for the development of self-healing materials with a permanent crack-healing ability to be applied in high-temperature components such as gas turbine blades.
