电子束物理气相沉积（EB-PVD）热障涂层（TBC）的发展目标是低电导率、提高耐温能力和延长使用寿命。通过对柱状陶瓷表面涂层多孔微观结构演变的全面了解，以及将其应用于优化微观结构的研究，取得了相当大的进展。新的陶瓷组合物，如替代稳定剂在氧化锆，半氧化铪改性涂层，和焦绿石讨论。它们已经证明了它们在未来TBC应用中的潜力。本文从微观结构和化学两方面介绍了新的研究成果，并对近年来的研究成果进行了总结。
Development of electron beam physical vapor deposited (EB-PVD) thermal barrier coatings (TBC) aims at low conductivity, increased temperature capability, and longer life. Considerable progress has been achieved by comprehensive understanding of the evolvement of the porous microstructure in columnar ceramic topcoats and its application to tailoring optimized micro-structures. New ceramic compositions such as alternative stabilizers in zirconia, hafnia modified coatings, and pyrochlores are addressed. They have demonstrated their potential for future TBC applications. New results of both microstructure and chemistry are presented together with a summary of recent research results.
