摘要

Four nanostructured Y_2O_3-ZrO_2(YSZ), 4mol%Gd_2O_3-YSZ(4Gd-YSZ), 6mol%Gd_2O_3-YSZ(6Gd-YSZ), 8mol%Gd_2O_3-Y_2O_3-ZrO_2(8Gd-YSZ) coatings were prepared by atmospheric plasma spraying (APS) technology under the same spraying parameters. The phase composition, microstructure, hardness, adhesion strength, thermal shock behavior and failure mechanism of nano-YSZ and GdYSZ were investigated systemically. The results showed that the as-sprayed GdYSZ coatings were consist of tetragonal ZrO_2 (t-ZrO_2) and Gd element was in solid solution with t-ZrO_2. The value of hardness, adhesion strength and thermal shock life for the as-sprayed nano-YSZ, 4Gd-YSZ, 6Gd-YSZ, 8Gd-YSZ coating were: YSZ > 4Gd-YSZ > 6Gd-YSZ > 8Gd-YSZ. Our investigations proved that the dopants Gd_2O_3 had the obvious effect on YSZ, that is Gd_2O_3 decreased the hardness, deteriorate the adhesion strength, and reduced thermal shock life. The more of Gd_2O_3 and the effect is obvious. Reasons of different properties for them were also analyzed in detail.
