Abstract

This work proposes a multi-composition oxidation resistant coating for SiC-coated carbon/carbon (C/C) composites by slurry method using the mixture of Y₂O₃, ZrO₂, Al₂O₃, Si and C. XRD analysis shows that the phases of the composite coating are composed of SiC, Al₂O₃, Y₂O₃, ZrO₂, Al₄SiC₄ and Y₃Al₂(AlO₄)₃. SEM analysis of the cross section of the coating displays the microstructure with 500 μm thickness which filled the porous SiC. Oxidation test shows that, after 19 h oxidation in air at 1873 K, the weight loss of the coated SiC-C/C is only 1.76%. The oxidation of the coated C/C composites was primarily due to the reaction of C/C matrix and oxygen diffusing through the penetrable cracks and bubble holes in the coating.
