【摘要】 采用涂刷法制备了炭／炭(C／C)复合材料磷酸盐防氧化涂层,经过氧化性能测试, 证明其具有良好的氧化防护作用。涂覆有该涂层的C／C试样700℃下经过100h的氧化,其失重率仅为0．96％,经过900℃(2min)←→室温(3min)的热循环实验,循环次数为50次,失重率仅为1．32％。更多还原

【Abstract】 A kind of phosphate oxidation protective coating for carbon/carbon(C/C) composites is prepared using slurry brushing processes. The results show good oxidation-resistance properties. After an oxidation time of 100h at 700℃, the weight loss is only 0.96%. And after thermal cyclic oxidation tests, the coating is also demonstrated to exhibit good oxidation-resistance properties.更多还原
