摘要：A graphite coating was fabricated on low density carbon/carbon composites by a slurry coating technology. SiC coating was prepared using direct reaction of silicon vapor and graphite coating through silicon evaporation. The influence of evaporation temperature, evaporation time, atmosphere, silicon evaporation source and surface roughness of graphite coating on the micrograph, phase constitution, density, surface evenness and thickness of SiC coating were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that the surface evenness of SiC coating increases gradually with the increase of evaporation temperature. Only SiC exists on coating surface at the evaporation temperature of 1550, 1650. Using silicon block as silicon source and argon as protective gas, the surface evenness of SiC coating is enhanced. The density and continuity of coating can be improved by reducing the surface roughness of graphite coating. With increasing evaporation time, the thickness and density of SiC coating gradually increases. ©, 2015, Beijing Institute of Aeronautical Materials (BIAM). All right reserved.
