采用脉冲电弧放电沉积法制备了SIC预涂碳/碳复合材料（SIC -C/C）的抗氧化AlPO4涂层。研究了脉冲占空比对镀层组成、组织和抗氧化性能的影响。结果表明，当脉冲占空比从10%提高到30%时，AlPO4涂层的厚度、致密性和抗氧化性能均有所改善。脉冲占空比为30%时制备的多层涂层具有良好的抗氧化性能，可以有效地保护C/C复合材料在1773 K空气中氧化148 h，重量损失为0.82%。(C) 2013 Elsevier Ltd.版权所有。
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%.
