用于当前发电设备（如燃气轮机）的新材料的进步导致了更高效、更耐用的发动机，以满足不断增长的能源需求。由于更高的工作温度，燃气涡轮机的高效率已经通过热障涂层的开发来实现。这些是多层系统，提供隔热能力和防腐蚀和高温侵蚀的保护。在这项工作中，我们描述了屏障的应用过程，其微观结构特征和主要的故障机制。两种不同的热障涂层的特点和这些系统的最相关的趋势进行了总结。
Advances in new materials for current power generation devices, such as gas turbines, have led to more efficient and durable engines that supply rising energy demands. High efficiencies in gas turbines, due to higher operating temperatures, have been accomplished through the development of thermal barrier coatings. These are multilayered systems that provide thermal isolation capability and protection against corrosion and high temperature erosion. In this work, we describe the barrier’s application processes, their microstructural characteristics and their main failure mechanisms. Two different thermal barrier coatings are characterized and the most relevant trends of these systems are summarized.
