Carbon / carbon composites (hereinafter referred to as "C / C or CFC") is a kind of composite material which is based on carbon and reinforced by carbon fiber and its products (carbon fiber preform). It has both the inertia of carbon and the high strength of carbon fiber. It has good mechanical properties, heat resistance, corrosion resistance, friction damping and thermal and electrical conductivity characteristics
CVD-SiC coating has the characteristics of uniform structure, compact material, high temperature resistance, oxidation resistance, high purity, acid&alkali resistance and organic reagent, with stable physical and chemical properties.
Main features:
1. High temperature oxidation resistance: the oxidation resistance is still very good when the temperature is as high as 1600 C.
2. High purity: made by chemical vapor deposition under high temperature chlorination condition.
3. Erosion resistance: high hardness, compact surface, fine particles.
4. Corrosion resistance: acid, alkali, salt and organic reagents.
