| 英文摘要 | Gadolinium zirconate is a promising next-generation thermal barrier coating material and its CaO-MgO-Al2O3SiO2 (CMAS) resistance needs to be further increased. In this study, three gadolinium zirconate coatings with different Gd/Zr ratios are successfully prepared via atmospheric plasma spray using amorphous feedstock. Their mechanical properties and corrosion resistance are investigated. The Young?s moduli and hardness of as-sprayed coatings are comparable with the gadolinium zirconate coatings reported in previous literature. Furthermore, the higher Gd content promotes the formation of the Gd-apatite and the depletion rate of CMAS corrosion. As a result, the infiltration depth of Gd2.3Zr1.7O6.85 coating after 24 h annealing decreases up to 35 % compared with those of Gd2.0Zr2.0O7.0 and Gd1.8Zr2.2O7.1, exhibiting an enhanced long-term corrosion resistance. This work develops a viable fabrication method to produce non-stoichiometric gadolinium zirconate coatings with tailorable CMAS corrosion resistance and is expected to promote the future design of thermal barrier coatings with long service life. |
