英文摘要	In order to improve the oxidation resistance of carbon material, a sic/si-mosi2, oxidation protective coating was prepared on graphite substrate. the graphite substrate was firstly infiltrated with silicon in vacuum atmosphere to obtain 220 mu m thickness sic inner layer, and 80 mu m thickness si-mosi2 outer layer was made by using a si-mo slurry. the effect of mo/si of slurry and sic inner layer on the oxidation resistance of coating was studied. results indicated that the as-received coating with the mo/si of 40% in the slurry has excellent oxidation protection for long life at 1673 k in air. the sic inner layer acts as a barrier to prevent the infiltration of liquid si into the pores of the graphite substrate during the sintering of the outer layer and is beneficial to maintain the mo/si of 40% in the slurry. the improvement of coating properties can be attributed to the well-coating microstructure. the mechanism of the oxidation resistance of the coated graphite is also discussed.
