Abstract
A multilayer B2O3-modified MoSi2-CrSi2-Si/B-modified SiC coating system was prepared on the surface of carbon/carbon (C/C) composites by a three-step pack cementation method. The microstructure, oxidation resistance and thermal cycling test of the multilayer coating were studied. The results show that the coating system exhibits good oxidation resistance from room temperature to 1873K. It can protect the C/C composites from isothermal oxidation in air at 1173K for 150h or 1873K for 900h, respectively. It can also resist 30 thermal cycles between 1873K and room temperature.
