Abstract

In order to protect carbon/carbon(C/C)composites from oxidation at 1700°C, aMoSi2–SiC–Si/MoSi2coating was prepared on the surface of these composites by a simple and effective method. TheMoSi2–SiC–Siinner layer was obtained by pack cementation, and theMoSi2outer layer was prepared by slurry coating using silicon-sol as the caking agent. The microstructures of the as-prepared coating were examined by X-ray diffraction and scanning electron microscope. Oxidation test shows that, the as-received coating can protectC/Ccomposites from oxidation for more than 107 h at 1700°C in air. The excellent anti-oxidation ability of this coating is attributed to its dense structure and the formation of theSiO2film on the coating surface during oxidation.
