高温防护涂层用粘结层研究进展
Research Progress of Bond Coats for High-temperature Protection Coatings
摘要
Abstract
Aero engines and gas turbines,as national strategic equipment,have a profound impact on national defense security,energy security,and technological innovation.With technological advancements and the pursuit for enhanced efficiency,the combustion chamber temperatures of aero engines and gas turbines continue to rise,subjecting hot-section components to severe challenges of high temperature,oxidation and corrosion.Surface coating technology is a key solution to increase the service temperature and corrosion resistance of components,among which thermal barrier coatings,environmental barrier coatings,and integrated thermal/environmental barrier coatings are the mainstream protective coating systems.Regardless of the various coating systems,a bond coat is required between the top coat and the substrate(superalloy/ceramic matrix composite).This layer,designed with a matched coefficient of thermal expansion,effectively alleviates thermal stress and reduces the risk of coating cracking;its active elements can also react with oxygen to form a dense oxide layer,preventing substrate oxidation and thus determining the overall lifespan of the coating system.This paper systematically summarizes the material characteristics,technical advantages,and limitations of bond coats for different coating systems,and reviews the research progress.It introduces the preparation techniques for bond coats,analyzes their suitability in service environments,and identifies current technical bottlenecks in research.Finally,it discusses the future development trends of bond coat technology.关键词
