摘要
石墨、炭纤维、炭/炭复合材料等碳基材料广泛应用在航空航天、能源汽车、化工等领域,但炭材料在高温有氧环境下易氧化和不耐氨气、耐划性能较差等缺点,难以满足人们对炭材料越来越苛刻的使用要求,严重制约其发展和实际应用。碳化钽(TaC)具有优异的高温力学稳定性及高温耐腐蚀、耐烧蚀等优点,并与炭材料具有良好的化学相容性和力学相容性,能够对炭材料有效保护,引起国内外研究人员对TaC涂层改性碳基材料的广泛研究。本文系统介绍了在石墨、炭纤维、炭/炭复合材料3种碳基材料表面制备TaC涂层的研究进展,阐述了化学气相沉积工艺(如气体流量、沉积温度、沉积压力)对TaC涂层改性碳基材料的影响规律,讨论了TaC涂层的发展趋势及展望了发展方向。
Carbon materials,such as graphite,carbon fibers and C/C composites,have a high specific modulus and specific strength,especially at high temperatures.However,they corrode easily in air or ammonia at high temperatures and have poor scratching resistance.Tantalum carbide(TaC)has an excellent high-temperature mechanical stability,high-temperature corrosion resistance,high-temperature ablation resistance and good chemical and mechanical compatibility with carbon materials.This paper summarizes research progress on coating TaC on graphite,carbon fibers and C/C composites.The coating methods and their effects on the properties of carbon materials are introduced,including plasma spraying,chemical vapor deposition,chemical vapor infiltration,slurry coating,sol coating and reactive coating in molten salt media with a focus on chemical vapor deposition.Development trends and research directions on the subject of TaC coating are discussed.
