摘要

A facile pulse arc discharge deposition method was developed to prepare AlPO4 oxidation resistant outer coating on SiC pre-coated carbon/carbon composites (SiC-C/C). The deposition dynamics and the influence of pulse frequency on composition, microstructure and oxidation resistance of the as-prepared coating were investigated. Results show that pulse arc discharge deposition is an effective route to achieve dense and crack-free AlPO4 coatings. The deposition activation energy of the AlPO4 coating is calculated to be 3.07 kJ·mol-1. The AlPO4 coating prepared at a pulse frequency of 2000 Hz exhibits good oxidation resistance, which can effectively protect C/C composites from oxidation in air at 1773 K for 262 h with a weight loss of 1.58%.
