Abstract

Oxidation protective SiC nanowire-toughened CrSi ₂-SiC-Si coating was prepared on SiC-coated carbon/carbon composites by chemical vapor deposition and pack cementation. SiC nanowires in the coating suppressed the cracking of the coating via various toughening mechanisms including nanowire pullout, microcrack bridging by nanowire and microcrack deflection, resulting in a good oxidation inhibition for the coated samples. The results showed that the maximal weight loss of the coated samples was only 2.55% in thermogravimetric analysis from room temperature to 1500°C, and the weight loss of the coated samples was only 1.24% after isothermal oxidation at 1500°C for 316h.
