Abstract:

The research background, significance and current status of high/ultra-high temperature thermal barrier coatings (TBCs) for aero-engine applications are briefly highlighted. The recent research progress in new generation TBCs for ultra-high temperature applications is reviewed. Emphasis is laid on the recent research achievements of Beihang University which involves new ceramic topcoat materials with superior-high temperature capabilities and thermal barrier performances, novel metallic bond coat materials with good oxidation resistance at temperatures above 1 150 ℃, new processing technologies of TBCs including electron beam physical vapor deposition (EB-PVD), plasma activated EB-PVD (PA EB-PVD) and plasma spray physical vapor deposition (PS-PVD). Eventually, the prospective trends of TBCs for advanced aero-engine applications are forecast.

Key words: aero-engines, thermal barrier coatings, ceramics, bonding layer, plasma activated, electron beam physical vapor deposition, plasma spray physical vapor deposition
