To protect carbon/carbon (C/C) composites against oxidation, a MoSi2 outer coating was prepared on pack-cementation SiC coated C/C composites by a hydrothermal electrophoretic deposition. The phase composition, microstructure and oxidation resistance of the prepared MoSi2/SiC coatings were investigated. Results show that hydrothermal electrophoretic deposition is an effective route to achieve crack-free MoSi2 outer coatings. The MoSi2/SiC coating can protect C/C composites from oxidation at 1773 K for 346 h with a weight loss of 2.49 mg cm(-2) and at 1903 K for 88 h with a weight loss of 5.68 mg cm(-2).
