The drawback of easy oxidation for carbon/ carbon (C/ C) composites has limited their application as
structural materials in aerospace field. The oxidation protective coating is one of the most effective methods that can
realize the long term oxidation protection for C/ C composites at high temperatures. The recent development of oxidation
protective coating materials for C/ C composites, including glass, metal and ceramic coatings were reviewed. The
advantages and defects of traditional preparation technologies as well as their application were analyzed and summarized.
New advances in development of coating technologies were also introduced, and then, the suitable service environment
and recent application of different coating systems were clarified. To meet the ultra high temperature oxidation
protection for C/ C composites above 1 800℃, the problem in recent study and the potential development directions in
the future were proposed.
