摘要：ZrB2 composite coating was prepared by CVD and tape casting in order to realize the low cost and ultra-high temperature performance of SiC ceramics. The oxidation behavior of the as-prepared ZrB2 composite coating was studied. The results show that the oxidation of ZrB2 occurred at relatively low 800 degrees C. With the increase of temperature, the content of glassy phase increased. When oxidized at 1600 degrees C, the microcracks were evident in the SiO2 glassy phase because of the thermal expansion coefficient mismatch between ZrO2 and ZrB2.
