Abstract

A dense double layer ZrB₂-SiC-Si/SiC-Si coating with high content of ZrB₂ was designed and fabricated by dipping-carbonization joint gaseous silicon infiltration. This coating can protect C/C substrate from oxidation in air at 1773 K for 500 h with a weight gain of 1.14 %. Such good oxidation protective performance was ascribed to the dense compound silicate oxide layer accompanied by ZrSiO₄/ZrO₂ pinning phases and compressive stress field around ZrB₂ particles during oxidation. Besides, introducing abundant ZrB₂ phase could inhibit the evaporation of silicate glass at 1973 K, which could protect C/C composites for 78 h with a weight loss of 1.16 %.
