To improve the oxidation resistance of graphite at high temperature, a dense ZrC-SiC multi-coating was prepared on graphite with ZrSiO4 powder by pack cementation. The structure and morphology of the multi-coating were characterized by XRD, SEM and EDS analysis, and the formation of the coating was discussed with thermodynamics calculation. The results show that the coating has a double-layer structure, which consists of SiC-rich inner layer and ZrC out layer. Besides ZrC and SiC phases, SiC crystals are also formed in the coating. The formation of the double-layer structure is primarily attributed to the different generation temperatures of the reductive products in the system, and the dense structure of the multi-coating can be obtained due to the excellent flowing and filling ability of the liquid Zr formed in the preparation process.
