Anti-oxidation properties of a Si
SiOx/BNB2O3SiO2Al2O3 dual-layer coating are investigated.- •
The Si
SiOx/BNB2O3SiO2Al2O3 coating has a good oxidation protection ability at intermediate temperature.- •
The Si
SiOx layer can densify the pores in C/C composites efficiently and improve the oxidation resistance of the samples.- •
The oxidation kinetics model of the Si
SiOx/BNB2O3SiO2Al2O3 corresponds to two different oxidation mechanisms.
