成果简介:Pulse arc discharge deposition was developed to prepare an oxidation-protective AlPO4 coating for SiC pre-coated carbon/carbon composites (SiC-C/C). The influence of pulse duty ratio on composition, microstructure and oxidation resistance of the as-prepared coatings was investigated. Results show that thickness, compactness and oxidation protective property of the AlPO4 coating were improved with the increase of pulse duty ratio from 10% to 30%. The multi-layer coating prepared at a pulse duty ratio of 30% exhibits good oxidation protective property, which can effectively protect C/C composites from oxidation in air at 1773 K for 148 h with a weight loss of 0.82%.
