Enhancement of the self-healing ability in oxidation induced self-healing ceramic by modifying the healing agent

Abstract

The available temperature range of the self-healing induced by high temperature oxidation of SiC can be controlled by the particle size of the contained SiC particles. In this study, three types of alumina–SiC composites were prepared. The SiC particle sizes of the composites were 270, ∼30 nm, and less than 10 nm. The self-healing abilities were estimated by the strength recovery behavior at several temperatures.
