Oxidation properties of tri-layer ytterbium-disilicate/mullite/silicon-carbide environment barrier coatings for Cf/SiC composites

Mullite (Al6Si2O13) and ytterbium disilicate (Yb2Si2O7) powders were synthesized by the solvent gel (sol-gel) method. To improve the oxidation resistance of Cf/SiC composites at high temperatures, a novel tri-layer Yb2Si2O7/Al6Si2O13/SiC environment barrier coatings (EBCs) was deposited on the surfa...
