THE INVESTIGATION ON INTERFACE OF THE OXIDATION RESISTANT COATING OF CARBON-CARBON COMPOSITE

摘要

摘要: 本文研究了碳-碳(C/C)复合材料的碳化硅抗氧化涂层系统的组成和成型工艺,给出了抗氧化性能试验和动态环境试验结果.经微观结构分析,认为在C/C基材表面反应生成的碳化硅涂层是化学转化涂层,与C/C基材是有机结合,并且具有成分连续变化的过渡界面,构成了一种功能梯度倾斜材料,使固渗碳化硅具有优异的性能.

Abstract: The component and processing of the carbon-carbon (C/C) composite with diffusion type coating have been studied,and the results of the oxidation resistant performance and dynamic environment tests are given.It has been shown by analyzing the microstructure,that SiC coating formed by the reaction on C/C composite surface is the combination of chemical convetting coating and C/C composite,which is gradient interface of which components are continuously changing where it constructs the functionally gradient material,makes SiC coating have excellent performances.
