| description | The invention discloses a multi-element high-entropy stable yttrium oxide thermal barrier coating material and a preparation method thereof, the thermal barrier coating material is obtained by taking a Y2O3 ceramic material as a matrix and performing high-entropy doping of four or more divalent metal elements with equal molar weight on a Y site, and the doped divalent metal elements are selected from any four or more of Be, Mg, Ca, Sr, Ba, Zn and Co. The multi-element high-entropy stable yttrium oxide thermal barrier coating material is greatly improved in the aspects of thermal conductivity, bonding strength, thermal insulation performance, thermal cycle life and the like, the preparation method is reliable in process, stable in performance, high in efficiency and low in production cost, and the multi-element high-entropy stable yttrium oxide thermal barrier coating material is suitable for being applied to the field of high-thermal-insulation protection of hot-end components and has good popularization pros |
