工业燃气轮机市场的不断增长导致对大型、具有成本效益的高效率机组的需求不断增加。开发此类机组的一个关键问题是热段部件的耐用性，特别是应用热障涂层（TBC）的第一级叶片和轮叶。本文介绍了 TBC 生产的最新技术，并讨论了它们的各种降解机制。特别强调通过控制微观结构和孔隙率以及新的加工技术开发新一代热障涂层系统的潜力。
The growing market for industrial gas turbines has led to an increased demand for large, cost-effective units of high efficiency, A critical issue in the development of such units is the durability of hot section components, especially first stage blades and vanes to which thermal barrier coatings (TBCs) are applied. This paper introduces the current state of the art in the production of TBCs, and discusses their various degradation mechanisms. Special emphasis is placed on the potential for the development of a new generation of TBC systems through the control of microstructure and porosity, as well as through new processing techniques.
