| Abstract: | A new kind of multi anti-oxidation coating was designed and manufactured by pack cementation and brushing method in this work.The coating was composed of self-healing inner layer,thermal expansion coefficient(CTE) matched intermediate layer and oxygen barrier layer.Morphology and component of the coating were carried out through scanning electron microscopy(SEM),X-Ray diffraction(XRD) and also the properties of anti-oxidation and thermal shock resistance were analyzed at temperatures of 1 000 ℃,1 300 ℃ and 1 400 ℃.The results show that the coating can protect the C/C composites for more than 50 h at 1 400 ℃ and it is still intact after 20 thermal cycle from room temperature to 1 400 ℃. |
