摘　　要：在碳纤维表面制备碳化硼涂层能改善碳纤维的抗氧化性能,避免在复合材料制备过程中碳纤维与基体发生界面反应。以碳纤维表面碳化硼涂层的制备为主线,分析了化学气相沉积法、直流电阻加热法和射频加热法等制备工艺,回顾了碳化硼涂层制备过程中的原料选择、热力学和动力学研究。The oxidation resistance properties of carbon fiber can be improved by tabncatmg boron cartnae coating on carbon fiber , and the interface reaction of carbon fiber and matrix can be avoided during the preparation of composites. In this paper choosing the preparation of boron carbide coating on carbon fibers as the main line,the preparation technologies about CVI）, EIC electrically heating and radio frequency direct-heating are analyzed, The new material seletion , thermodynamics and kinetics are also reviewed during the fabrication of boron carbide coating.
