摘要:
热障涂层（TBC）是航空发动机、燃气轮机热端部件的表面防护关键技术，通过降低热端部件的表面温度显著提升其在发动机恶劣工况下的服役可靠性与使用寿命。TBC的制备技术有大气等离子喷涂（APS）、电子束物理气相沉积（EB-PVD）、等离子物理气相沉积（PS-PVD）、悬浮液等离子喷涂（SPS）等。其中，SPS通过液相送料的方式，能够解决纳米尺度粉末喷涂时的输运难题，实现兼具低热导率与高应变容限TBC的低成本制备，在TBC制备领域展现出巨大的应用前景。综述了近年来SPS制备TBC的研究进展：介绍了SPS技术特点、涂层沉积机理和涂层结构特征，详细阐述了SPS涂层结构的影响因素，分析了溶剂类型、溶质粒径、固含量、分散剂种类等悬浮液特性，喷涂功率、等离子气体、喷涂距离、送料速率等喷涂工艺参数，粘结层表面状态以及多因素耦合对SPS涂层结构的影响；梳理了SPS涂层在热导率、热循环寿命、高温腐蚀性能等方面的研究成果，探讨了涂层结构与性能需求的匹配问题；介绍了SPS制备稀土掺杂YSZ、稀土锆酸盐等新型TBC以及双层/多层结构TBC的研究进展；最后，展望了SPS制备TBC的未来发展方向。
Abstract:
Thermal barrier coating (TBC) is a critical surface protection technology for hot-section components in aero-engines and gas turbines. By reducing the surface temperature of these components, TBC markedly enhances their service reliability and operational lifespan under severe engine environments.The primary fabrication routes for TBC include atmospheric plasma spraying (APS), electron beam physical vapor deposition (EB-PVD), plasma spray-physical vapor deposition (PS-PVD) and suspension plasma spraying (SPS). Among these, SPS employs a liquid feedstock to circumvent the feeding difficulties associated with nanoscale powder spraying, enabling the cost-effective fabrication of TBCs with both low thermal conductivity and high strain tolerance, thereby holding considerable promise in the field of TBCs. This review summarizes recent advances in SPS TBCs. The technical characteristics, deposition mechanisms and resultant microstructures of SPS coatings are first introduced. The factors governing coating microstructure are then systematically examined, including suspension properties (solvent type, particle size, solids loading and dispersant type), spray parameters (power, plasma gas composition, stand-off distance and feed rate), bond coat surface condition, and their synergistic effects. Subsequently, the performance of SPS TBCs-specifically thermal conductivity, thermal cyclic lifetime and high-temperature corrosion resistance is assessed, with emphasis on the interplay between microstructure and performance requirements. Recent developments in novel SPS TBC material systems, such as rare-earth-doped YSZ, rare-earth zirconate ceramics and double-layer/multi-layer configurations, are also reviewed.Finally, future directions and challenges for the development of SPS TBCs are proposed.
