Abstract

To prevent the carbon/carbon (C/C) composites from ablation, a new type of ablation protective coating was prepared on the surface of theC/Ccomposites by a step pack cementation technique. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis show, the coatings obtained by pack cementation were silicon carbide/tantalum silicide (SiC-TaSi2). The ablation behavior of the coated samples were evaluated by the oxyacetylene flame. The results show that, theSiC-TaSi2coating can improve the anti-ablative properties ofC/Ccomposites effectively. The mass ablation rate for the coatedC/Ccomposites was only 7.7 × 10-4g/s, which was lower by 79% than that of theC/Ccomposites after ablation for 30 s.
