A Multi-Step Deposition Strategy for β-SiC Coatings on C<sub>f</sub>/C Composites: Achieving Breakthrough Oxidation Resistance and Mechanical Properties.
Ontology highlight
ABSTRACT: Current SiC coating technologies for anti-oxidation Cf/C composites, such as pack cementation, often rely on high-temperature in situ reaction with severe mechanical property decay. Chemical vapor deposition (CVD) presents a promising alternative for fabricating anti-oxidation SiC coatings with long service life and high mechanical property. However, existing CVD approaches suffer from poor crack sealing and rapid oxidation loss, leading to insufficient anti-oxidation time. Therefore, achieving long-term anti-oxidation SiC coatings using CVD remains a crucial challenge. This work presents a straightforward multi-step deposition strategy for fabricating anti-oxidation Cf/C composites with long service life and high mechanical properties. The anti-oxidation time of β-Si
