【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 MCr Al Y coating, anti-erosion nitride coating and YSZ thermal barrier coating, were introduced.更多还原
