More effective crack self‐healing capability of SiCf/SiC‐B4C with …
Aluminum oxide has been introduced into SiC f /(SiC + B 4 C) composites to improve the crack self-healing property in O 2 /H 2 O atmosphere. The observation of the surface and interior morphologies of the oxidized composites reveal that Al 2 O 3 can lead to rapid self-healing of cracks, which will effectively block the oxidation of interior ...
