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 °C. With the increase of temperature, the content of glassy phase increased. When oxidized at 1600 °C, the microcracks were evident in the SiO2 glassy phase because of the thermal expansion coefficient mismatch between ZrO2 and ZrB2.
