摘要：
A two-dimensional mathematical model for deposition behavior of SiC coating on C/C composites in a hot-wall CVD reactor was developed. Deposition rate of SiC was calculated by finite element method and optimized by using an orthogonal L-9(3)(4) test. The single and coupling effects of process parameters on deposition rate of SiC, including deposition temperature, the flux of mixed gases, the volume ratio of H-2 and Ar, and that of MTS and mixed gases, were Calculated and discussed. The optimal deposition rate of SiC was obtained.
