Progress in Research on High Temperature Protective Coatings for Aero-engines

Aeroengines provide one of the demanding environments challenging material systems. Engine components are subject to rigorous mechanical loading conditions, high temperatures, and corrosive or erosive media. High temperature protective coatings were applied to increase the durability and field performance of hot sections of aeroengines. In this paper, recent progress in research on the design, materials and processing for high temperature protective coatings were reviewed. Trends of research and application on high temperature protective coatings for aeroengines of the next generation were also anticipated.
