High performance SiC oxidation protective coating with ZrO 2 particle dispersion for C/C composites was prepared by slurry and pack cementation. Isothermal oxidation tests at 1873 K in air showed that the as‐prepared coating could effectively protect C/C composites from oxidation for 100 h. The excellent oxidation protective ability can be attributed to the introduction of ZrO 2 particles in the SiC coating, which can baffle the enlargement of cracks and suppress the generation of the thermal stress.
