Carbon-carbon compound material is given an oxygen barrier cladding, with a coating of silicon to be heated for impregnation, as a protection against oxidizing when used in an oxygen atmosphere |
摘要 |
<p>To coat the surfaces of a carbon/carbon compound material, as an oxygen barrier, the material surface is coated with silicon and the compound material is heated to give a silicon impregnation, at a temperature of 1400-1600[deg]C under a pressure of 1.332-133.32 Pa. The operation initially forms a SiC layer followed by a Si layer. The Si layer is oxidized at 400-800[deg]C to form a SiO 2 film. The total layer structure has a thickness of 10-2000 mu m.</p> |
