| Abstract: | The structures and oxidation behaviors of some kinds of high performance ceramic coatings produced by us for carbon/carbon (C/C) composites were introduced in this paper. It showed that the multi-layer coatings such as Si-MoSi_2, SiC-MoSi_2, Al_2O_3-mullite-SiC-Al_4SiC_4 and Al_2O_3-mullite-SiC coatings prepared by pack cementation and infiltration process possess excellent oxidation protective property for C/C composites at high temperatures, and some of the coatings characterized by excellent thermal shock resistance could effectively protect the C/C composites from oxidation up to 1973K. In addition, the protection and failure of some multi-coatings at high temperature was also discussed. |
