摘要:
In this study, Gd-2(Hf-0.Ti-7(0).(3))(2)O-7 ceramics were synthesized by a high-temperature solid-state method, and the feasibility of using it as thermal barrier coating was systematically studied. This study primarily investigated the thermal physical properties, mechanical properties, and calcium-magnesium-alumina-silicate oxides (CMAS) corrosion resistance of the Gd-2(Hf-0.Ti-7(0).(3))(2)O-7 ceramic bulk. The results indicated that the thermal expansion coefficient of Gd-2(Hf-0.Ti-7(0).(3))(2)O-7 ceramics was close to that of 6 similar to 8wt% yttria-stabilized zirconia (YSZ). At 1000 degr...
