摘要
以便有效地采用唯一的高温度碳 / 碳的机械性质合成底层，原文如此，涂层增强了由原文如此，络腮胡子被包装硬化方法准备。效果原文如此，单个层的涂层和双层涂层的氧化抵抗性质上的络腮胡子被调查。原文如此络腮胡子在单个层原文如此涂层在反氧化性质上有小效果，但是显然改进热吃惊性质。有内部层的增强的涂层的双层涂层与原文如此内部层的涂层比双层涂层展出更多的完美的反氧化能力。
In order to effectively employ the unique high temperature mechanical properties of carbon/carbon composite substrates, SiC coatings reinforced by SiC whiskers were prepared by pack cementation method. The effect of SiC whiskers on the oxidation resistance properties of the single-layer coating and double-layer coating was investigated. SiC whiskers in the single-layer SiC coating have little effect on the anti-oxidation property but obviously improve the thermal shock property. The double-layer coating with inner-layer reinforced coating exhibits more perfect anti-oxidation ability than the double-layer coating with SiC inner-layer coating.
