New advancement of oxidation protective coatings for C/C composites

The recent advancement of the oxidation protective coatings of C/C composites in China was reviewed. New technologies and new improvements of the traditional coating preparation technologies for C/C composites were introduced. According to the application conditions of C/C composites, the development trend of anti-oxidation coatings was also proposed. It was showed that the present research results could not meet the requirements of the coated C/C composites in severe work environments. The further researches would be focused on the preparation of suitable coating that could protect C/C composites from oxidation from room temperature to 1700°C in high speed gas-fired environments. To reduce the cost of preparation, the coating that could works at 1800°C for long time should be exploited.
