Abstract

In this paper, after reviewing the research on self-crack healing of ceramics, a mechanism of self-crack healing of ceramics containing silicon carbide (SiC) were introduced. Self-crack-healing phenomenon is mainly due to high-temperature oxidation reaction of SiC. Furthermore, depending on the conditions of temperature and stress during service, it was found that a surface crack can be healed completely during service. Next, the research on the improvement of rolling contact fatigue strength of ceramics by the combined use of shot peening and crack-healing was introduced. The development of materials having more excellent cracks healing ability is desired in the future. Through these, applications to high temperature structural ceramic member and sliding member or the like is expected to greatly advance.
