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
