| 摘要 |
<p>The invention concerns a method for densification and anti-corrosive treatment of a thermostructural composite material, comprising the following phases: a first densification by carbon chemical vapour infiltration in a densifying furnace with slow reaction rate of the diffusion gas and low reactivity so as to allow core penetration in the crucible support assembly, the density of the resulting crucible support being higher than 1.50 in the case of carbon/carbon, higher than 1.65 in the case of carbon/SiC and higher than 2.40 in the case of SiC/SiC, the thickness of the product hardening being less than 100 νm. The invention also concerns the resulting crucible support.</p> |
