Multi-element co-doped zirconium oxide thermal barrier coating material and preparation method thereof
The embodiment of the invention discloses a multi-element co-doped zirconium oxide thermal barrier coating material and a preparation method thereof. The multi-element co-doped zirconium oxide thermal barrier coating material is prepared from the following materials in mole fraction: 0.66 of zirconium oxide, 0.095-0.100 of trivalent rare earth oxide and 0.095-0.100 of pentavalent oxide, and the trivalent rare earth oxide and the pentavalent oxide are in equal molar ratio. The material has excellent CMAS lava corrosion resistance, and is expected to be used as a new-generation thermal barrier coating material with higher service temperature.
本发明实施例公开了一种多元共掺杂氧化锆热障涂层材料及其制备方法，所述材料由下列物料按照摩尔分数组成：氧化锆0.66、三价稀土氧化物与五价氧化物各0.095‑0.100，且三价稀土氧化物与五价氧化物等摩尔量配比。本发明具有优异的抗CMAS熔岩腐蚀能力，有望作为新一代服役温度更高的热障涂层材料。
