摘要：
With the aim of improving the creep resistance of titanium alloy, NiCrAlY (bond coat, BC)/yttria stabilized zirconia (top coat, TC) thermal barrier coatings (TBCs) were deposited on TA32 substrate,and the creep resistance of titanium alloy with TBCs was studied by test and numerical simulation.The results showed that there was a large difference between the creep rate of TA32 and that of TBCs. TC had an obvious constraint effect on the creep deformation of TA32 during tensile process at high temperatures, and the axial tensile stress of NiCrAlY BC in TBCs was larger than other parts. At 400℃ and 600℃, TBCs improved the creep resistance of TA32 by 5.6% and 17.5%, respectively. However, when the test temperature reached 600℃ and the tensile stress reached 200 MPa, severe cracking or peeling occurred in TC. © 2020, Editorial Department of Journal of Aerospace Power.
