摘要: Abstract The high-temperature erosion resistance of multi-layer MoSi 2 –CrSi –Si/SiC coated carbon/carbon (C/C) composites was investigated in a wind tunnel. To study the aerodynamic oxidation mechanism and analyze failure C/C composites, shear force bending moment distribution tested specimens tunnel were calculated. Flexural strengths thermogravimetric analysis measured. These results show that antioxidation coating can protect from at 1873 K for more than 86 h. Due to high viscosity SiO , lacked effective 900 1500 K, resulting extensive mechanical damage fracture specimens.
