摘　　要：采用化学气相沉积方法，在石墨基体上，在1623K，666Pa的条件下制各了SiC含量从0～100wt％全范围变动的C—SiC复合涂层材料，X—射线衍射表明，当SiC含量低于34wt％时，SiC以（220）面择优取向，而当含量高于34wt％时，SiC以（111）面择优取向。本文还对复合涂层的密度及硬度等性能做了测试。C/SiC composite coatings with differen content of SiC from 0 to 100wt% were prepared on graphite matrix under the condition of 1623K, 666Pa. by using CVD method. The result showed that when the content of SiC below 34wt%. the preferred orientation of SiC in composite coating was (220), otherwise. the preferred orientation was (111) by X-ray. The hardness and density of composite coating were also measured.
