热障涂层失效机理研究进展
Progress of Research on the Failure Mechanism of Thermal Barrier Coatings
摘要
Abstract
Thermal barrier coatings (TBCs) is one of the important materials of turbines for propulsion and power generation with excellent thermal insulation properties. At high temperature, the failure of TBCs will lead to serious problems, so the failure mechanisms is the hotspot of TBCs research. The microcracks caused by thermal stress and the TGO formation and growth will cause the failure of TBCs. The whole failure progress, such as the oxidation of the BC, the TGO growth process, initiation and propagation of the microcracks are reviewed in this paper. The factors led to the final failure are discussed, and the recent research progress on improving the lifetime of TBCs is summarized. In addition, the trend of the failure mechanism of thermal barrier coatings is described.关键词
