Structure Evolution and Thermo-Physical Properties of (La_(1-x)Gd_x)_2Zr_2O_7 Systems for BCs

摘要

With increasing operating temperatures of gas turbines for higher efficiency, the application of thermal barrier coatings (TBCs) on the metallic parts becomes necessary. Yttria-stabilized zirconia(YSZ) has been one of the most commonly used materials for TBCs due to its low thermal conductivity and thermal compatibility or/and stability with metallic substrates. As thermal requirements are going severe, research on
