Zusammenfassung:	The invention relates to a ZrO2 thermal barrier coating prepared by electron-beam physical vapor desorption. A preparation method of the ZrO2 thermal barrier coating comprises the following steps of: firstly, preparing stable nanometer zirconia powder with a large specific surface area by adopting ZrO(NO3)2 as a zirconium source and dropwise adding epoxypropane, and then preparing the ZrO2 thermal barrier coating by adding a right amount of Lu2O3, In2O3, A12O3 and TiO2 on the basis of the prepared stable nanometer zirconia powder with the large specific surface area. The prepared coating has good stability and high corrosion-resistant performance.
