The invention relates to a treatment method for improving the
oxidation resistance of a
thermal barrier coating (TBC) bonding layer, and belongs to the technical field of surface treatment and modification of the TBC bonding layer. In the material surface treatment and modification processes, the
surface roughness of the TBC bonding layer (MCrAlY) prepared by a
plasma spraying method is reduced through
high current pulsed
electron beam
irradiation, and the pores and holes of a
coating are reduced, so that the high-temperature
oxidation resistance of the TBC bonding layer is improved. Technical conditions are that vacuum degree is 3.5*10<-2>Pa,
voltage is 15kV, frequency is 1Hz, pulse width is 50 to 200mu s,
energy density is 8 to 18J / cm<2>, and pulse times is 10 to 20. The method has the advantages that the
surface roughness of the TBC bonding layer (MCrAlY) prepared by the
plasma spraying method is reduced through
high current pulsed
electron beam
irradiation, the pores and holes of the
coating are reduced, and penetrated microcracks are avoided, so that the high-temperature
oxidation resistance of the TBC bonding layer is effectively improved.
