摘要: To improve oxidation resistance of carbon/carbon (C/C) composites, a multiphase double-layer ZrB2-CrSi2-SiC-Si/SiC coating was prepared on the surface C/C composites by pack cementation. Thermogravimetry analysis showed that as-prepared could provide effective oxidative protection for from room temperature to 1490 °C. After thermal cycling between 1500 °C and temperature, fracture behaviors specimens changed their residual flexural strengths decreased as cycles increased. The specimen after 20 presented pseudo-plastic characteristics relatively high strength (83.1%), while 30 failed catastrophically without fiber pullout due severe damage substrate especially brittleness reinforcement fibers.
