摘要
Carbon-carbon composites are prepared to receive a subsequent protective coating by having a thin coating (0.1 to 5 mils) of chemically vapor deposited (CVD) SiC applied to its surface. The SiC layer improves the performance of subsequent protective coatings (especially pack produced SiC conversion coatings), especially in the case of carbon- carbon composites having a negative coefficient of thermal expansion.
