| 摘 要： | 通过控制化学气相沉积(CVD)工艺条件,得到粗糙层、光滑层、过渡层等几种具有不同微观结构的热解碳。金相观察、摩擦磨损性能的测试结果表明:热解碳的微观结构对炭/炭复合材料的摩擦磨损性能有重大影响;粗糙层结构的炭/炭复合材料摩擦因数高,热稳定性好,是一种优良的摩擦材料;光滑层结构的炭/炭复合材料摩擦因数低,磨损小,可以用作耐磨材料。

| Abstract: | Pyrolytic carbon of rough laminar, smooth laminar and transition can be achieved from different technologic conditions of chemical vapor deposition. Conclusions drawn from the micro-structural observation, friction and wear properties are that, the micro-structure of pyrolytic carbon have great influence on friction and wear properties of C/C composites, rough laminar is a kind of good friction material that have high friction coefficient and steady thermal conductivity, the smooth laminar can be used as a wear resistant material with a low friction coefficient and little abrasion. |
