C/C复合材料的抗氧化研究现状

Progress in Research on Oxidation Resistance of Carbon/Carbon Composites

目前提高C/C复合材料抗氧化能力的方法有CVI工艺法,浆料浸渍-热解工艺法,涂层法;抗氧化涂层的制备方法主要有化学气相沉积法(CVD),固态渗透法,涂刷法,等离子喷涂法,溶胶-凝胶法;抗氧化涂层有两种典型结构:单层涂层和复合涂层。指出了C/C复合材料高温氧化保护研究方向的发展趋势及前景。

Current research activities on oxidation resistance of C/C composites are described, including CVI, impregnation - pyrolysis, coating. The different oxidation- resistance coating systems and the preparing methods of coatings are emphasized in the discussion, mainly such as solid penetration, brush, plasma, sol - gel. Two kinds of oxidation resistance coating of C/C composites are given, the single coating and the compound coating. Prospects in the field of C/C composites with oxidation - resistance coating at high temperature are pointed out.
