在碳/碳复合材料上渗硅可得到碳化硅复盖层。对不同渗硅温度和时间下得到的碳化硅层进行破坏性试验。实验指出,有碳化硅复盖层保护下的碳/碳复合材料,其抗氧化性能提高约2个数量级。 Silicon carbide overlays on carbon / carbon composites. Destructive tests on silicon carbide layers obtained at different temperatures and times of siliconizing. Experiments show that, with silicon carbide covered under the protection of carbon / carbon composites, the oxidation resistance increased by about 2 orders of magnitude.
