Research Status of Thermal Barrier Coatings in Aero-engine Application
Abstract
With the increase of the operation environment requirements for aero-engine, the thermal barrier coating technology is difficult to satisfy the development requirement of aero-engine in the aspects of thermo-physical properties and thermo-stability. The preparation techniques of thermal barrier coating, design and selection of thermal barrier coating material, and failure mechanism of thermal barrier coating are introduced. The up-to-date research of material for better thermo-physical properties and better performance in CMAS(CaO-MyO-Al2O3-SiO2) resistance are discussed, which provide a direction for further research on thermal barrier coatings.
