摘要：

To improve the ablation resistance of carbon/carbon (C/C) composites, a SiC nanowire toughened ZrB2-SiC multiphase coating was prepared by a three-step technique including pack cementation, chemical vapor deposition (CVD), and supersonic atmosphere plasma spray (SAPS). The SiC nanowires helped improve the toughness of the ceramic coating. After ablation for 60 s under the heat flux of 4800 kW/m(2), the linear and mass ablation rates of ZrB2-SiC coating decreased from 4.9 mu m/s and 2.3 x 10(-3) g/s to 2.8 mu m/s and 1.4 x 10(-3) g/s after introducing SiC nanowires, respectively.
