Abstract Electron beam-physical vapor deposition (EB-PVD) is widely utilized for depositing thermal protective
coatings onto hot sections in aeroengines. The microstructure and service performance of the EB-PVD coatings can further
be enhanced by introducing plasma activation. In this paper, the state-of-art of plasma assisted EB-PVD was briefly
presented. Then the fabrication and evaluation of the coatings, including the anti-oxidation MCrAlY coating, anti-erosion
nitride coating and YSZ thermal barrier coating, were introduced.
