热障涂层（TBC）在施加到涡轮机部件表面时提供合金表面温度降低。热障涂层可用作设计者增加燃气涡轮机功率和/或提高效率的工具。热障涂层已成功地应用于航空航天工业多年，仅有限地用于工业燃气涡轮机应用。工业燃气轮机的运行周期和大修之间的时间要长得多，因此耐久性成为关键因素。有许多因素影响TBC的寿命，包括基体合金和粘结涂层的成分和微观结构。诸如Mar-M 247、CMSX-4和CMSX-10的合金是用于高温涡轮机环境的材料，并且通常需要保护和/或热障涂层以提高性能。元素如铪、铪和钇已经显示出这些合金强度的显著改善。然而，这些元素可能会对这些合金的可涂覆性和环境性能产生不同的影响。本文讨论了这些元素对隔热涂层性能的影响。
Thermal barrier coatings (TBCs) provide an alloy surface temperature reduction when applied to turbine component surfaces. Thermal barrier coatings can be used as a tool for the designer to augment the power and/or enhance the efficiency of gas turbine engines. TBCs have been used successfully in the aerospace industry for many years, with only limited use for industrial gas turbine applications. Industrial gas turbines operate for substantially longer cycles and time between overhauls, and thus endurance becomes a critical factor. There are many factors that affect the life of a TBC including the composition and microstructure of the base alloy and bond coating. Alloys such as Mar-M 247, CMSX-4, and CMSX-10 are materials used for high temperature turbine environments, and usually require protective and/or thermal barrier coatings for increased performance. Elements such as hafnium, rhenium, and yttrium have shown considerable improvements in the strength of these alloys. However, these elements may result in varying effects on the coatability and environmental performance of these alloys. This paper discusses the effects of these elements on the performance of thermal barrier coatings.
