Abstract:This paper briefly introduces the research background and development of thermal barrier coatings for gas turbine engines. Focusing on the EB-PVD thermal barrier coating preparation technology for engineering applications, it mainly presents the current research status at home and abroad in recent years in aspects such as coating preparation equipment, coating process -structure-performance, composite structure coatings, and the improvement of the protective capacity of thermal barrier coatings for turbine blades. Based on the development of high-performance gas turbine technology and the service conditions of hot-end components, the development trend of advanced thermal barrier coatings is finally prospected.
