    YSZ (ZrO 2-92wt.% Y 2O 3-8wt.%) powders with particle sizes of 15-45 m and 20-120 m, respectivelywere used as feedstock. The powders were mechanically milled (MM) in a high energy planetary ball mill at a revolution speed of 180 rpm for 24 h at room temperature under argon atmosphere. The milling process was performed with the time intervals of 3 h to

    Dec 25, 2016 YSZ transforms from the t′ phase to the tetragonal and cubic phases (t and c phases, respectively) during the cooling process after operating temperatures above 1200 C, and then to the monoclinic (m) phase with a volume expansion of about 3–5 vol% in further operation, resulting in the spallation or delamination of TBCs . In addition, the poor sintering resistance of YSZ at higher …

    Mar 03, 2018 Commercial CoNiCrAlY and YSZ powders, with particle sizes of 15–45 and 20–120 m, respectively, were used as the feedstock. Table 1 shows the composition of the used powders. The CoNiCrAlY powders were mixed with 0, 5, 10 and 15 wt% YSZ powder and milled mechanically in a high energy planetary ball mill at a revolution speed of 180 rpm for 24 h.

    Feb 01, 2020 The YSZ-LZ free-standing composite coatings were exposed at three different temperatures, i.e., 1100, 1300, and 1400 C for 100 h in an ambient atmosphere with a heating rate of 2 C min −1. After the tests, the YSZ-LZ free-standing coatings were cooled in the furnace, which reached room temperature after approximately 8 h. 2.3.

    Aug 30, 2018 The effect of co-sintering temperature on the YSZ microstructure was focused in this section. The YSZ films were deposited on NiO50A at the applied voltage of 30 V for 120 s, and the half-cells were subsequently co-sintered at 1200–1400 C. The surface microstructures of the co-sintered YSZ films were shown in Fig. 8a–d. The SEM results reveal the increase in grain size and the …
