摘要
设计并制备出了一种普通石墨材料抗氧化涂层,其基本结构为浸渍过渡层陶瓷相阻挡层玻璃相封填层。涂覆有复合涂层的普通石墨材料试样在空气中于900℃下氧化10h的失重率仅为006gcm2,氧化失重速率为101×10-4g(cm2·min);900℃←→室温空气中急冷急热10h循环100次后,失重率为874%,涂层没有剥落。
An oxidation resistance coating on common graphite was prepared The coating consisted of maceration transition layer,ceramal phase barrier and glass-phase blockage layer Fabrication technique,microstructure,function and mechanism of each layer were studied Results showed that weight loss of common graphite with the coating was only 0 06 g/cm 2 after oxidation in air and 900 ℃ for 10 hours,oxidation loss rate was 1 01×10 -4 g/(cm 2·min) Oxidation weight loss rate was 8 74% after thermal circulating so 100 times from 900 ℃ to room-temperature to 900 ℃ for 10 hours
