| 英文摘要 | electron-beam physical vapor deposited thermal barrier coatings (tbcs) with a double-layer bond coat of (ni, pt)al and nicralysi were prepared on a ni3al based single-crystal superalloy. phase and cross-sectional microstructure of the developed coatings were studied by using x-ray diffraction (xrd) and scanning electron microscope (sem), respectively. the experimental results show good adherence at all interfaces within this system. furthermore, oxidation resistance and elements interdiffusion behavior of the double-layer bond coat were also investigated. the double-layer bond coat system exhibits a better scale adherence than the single layer bond coat systems since the underlying (ni, pt)al layer can supply abundant al for the upper nicralysi layer. finally, thermal cycling behavior of the double-layer bond coat tbc was evaluated and the failure mechanism was discussed. crack nucleation, propagation and coalescence caused by tgo growth stress and the thermal expansion mismatch stress between tgo and bond coat can be mainly responsible for the spallation of this coating.
