| Abstract: | Ceramic materials fail to reach their full potential because of their sensitivity to cracks. Crack healing can result in a partial or complete recovery of the strength of the specimens with cracks, improve the reliability and prolong the lifetime of ceramic members. The crack healing mechanism, the influence factors of healing and the related changes of properties of crack- healed ceramics were reviewed in this paper. The problems needed to be overcome were also discussed. |
| Keywords: | Al2O3-matrix engineering ceramics crack healing |
