摘　　要：TaC 是一种具有广阔应用前景的抗烧蚀涂层材料。评述了近年来 Tac 粉末/涂层制备技术的研究和进展,简要总结了现有 Tac 粉末/涂层的制备技术,包括固相法、气相法和液相法等,讨论了各种制备技术的发展现状及其优缺点,介绍了国内 TaC 改性 C/C 复合材料的研究现状,提出了 TaC 用于 C/C 复合材料涂层时,其制备和应用中存在的问题以及解决方法,预测了 TaC 涂层在高温领域的广阔应用前景。TaC is a kind of coating material with huge prospect. In this paper, preparation techniques and developments of TaC powder/coating are valued in recent years. Preparation techniques, such as solid phase method, gas phase method and liquid phase method, are reviewed briefly. The recent progress, the advantages and disadvantages of different techniques are discussed at the same time. The recent research of TaC modified C/C composites in civil is introduced. Meanwhile, the problems still existing in the preparations and applications together with the solutions are indicated when C/C composites are coated with TaC. The broad prospect in high temperature field is predicted.
