摘要: 研究了碳/碳复合材料MoSi2防氧化涂层的性能.结果表明,MoSi2涂层系统具有1500℃长时间防氧化作用,在1500℃时,带涂层的碳/碳复合材料长时间氧化失重速率稳定在2.43×10-5g/m2·s,242小时的氧化失重为0.57%,该质量损失表现为涂层系统自身蒸发损耗;同时,MoSi2涂层具有良好的自愈性和抗热震性.Abstract: The processing of composite with MoSi2 type coating has been studied, and the results of the oxidation resistant performance are given. It has been shown that the weightloss percent of MoSi2 coating is less-than 0.57% and its weight loss ratio is steadily 2.43×10-5g/m2·s after 242 hours of oxidizing at 1500℃.
