Abstract An oxidation protective SiC/Si-MoSi2 / MoSi2 coating was prepared on graphite substrate by silicon infiltration and slurry sintering. Microstructure and anti-oxidation property of multi-layer coating were studied. Results showed that the inner layer,the intermediate transition layer,the outer layer is made of SiC,Si and MoSi2,MoSi2,respectively,and the functionally gradient coating was formed. The as-received coating characterized by excellent thermal shock resistance can effectively protect the graphite for long life at 1700 ℃ in air.
