摘要：

ZrB2-SiC coating on C/C composites was prepared through vapor silicon infiltration process. The coated C/C composites showed excellent oxidation performance at 1500 degrees C. Isothermal oxidation results showed that there was weight gain accompanied in the whole oxidation process and no evidence of oxidation of C/C composite substrate was observed. The thickness of coating increased from 120 mu m to about 200 mu m after oxidizing at 1500 degrees C. Three distinct layers could be observed in the coating, namely, outer SiO2-rich layer, middle ZrB2-rich layer, and inner SiC-rich layer. ZrB2 particles were coarsened after oxidation.
