Abstract The active oxidation of C/C composites at high temperature is a great obstacle for its application. In this study, a method of preparing SiC/Si–ZrB2–CrSi2/SiC multilayer oxidation-resistant coating for C/C composites by combining preoxidation and chemical vapor deposition (CVD) was proposed, and the results show that the coating has excellent oxidation resistance at 1473 K, 1573 K and 1673 K. Moreover, based on the uniform deformation model, the track of phases transition, lattice strain and internal stress for the protection/failure mechanisms at different temperatures/time were investigated by the agents of strain compatibility and stress distribution soured from XRD and Raman spectra.
