A silicon carbide coated carbon matrix/carbon fiber composite material is provided. The carbon composite base material, coated with silicon carbide, comprises a siliconized layer and a non-siliconized layer. The siliconized layer comprises silicon carbide matrix and non-siliconized carbon fibers. The siliconized layer also has a non-planar interface with a series of elongated protrusions penetrating into the surface the of non-siliconized layer. A gas-permeable intermediate coating formed on the carbon composite material can help produce such a siliconized layer.

Silicon carbide coated carbon composite material and method for making

A mirror for SOR includes a base (1) made of a heat resistant ceramic material having a surface, a first SiC coating (2, 3) formed on the surface of the base (1), which has a first smoothed surface, and a second SiC coating (4, 5) formed on the first smoothed surface of the first SiC coating (2, 3), which has a second smoothed surface. A third SiC coating can be formed on the smoothed surface of the second SiC coating (4).
