摘要
An in situ SiC nanowire-SiC-Si/SiC-Si protective coating was prepared on C/C composites by pack cementation and heat treatment. SiC nanowires suppressed the cracking of the coating by nanowire pullout and bridging and microcrack deflection, avoiding the oxidation of C/C composites. Results showed that the oxidation of the samples was a continuous weight gain process. The oxidation behavior was fitted to the parabolic-linear model and the final weight gain was 1.8% during thermogravimetric analysis from 50 to 1600 degrees C. The oxidation behavior was fitted to the parabolic model and the final weight gain was 0.51% during isothermal oxidation at 800 degrees C. (C) 2012 Elsevier Ltd. All rights reserved.
