High-entropy rare earth zirconate ceramic material for thermal barrier coating and preparation method of high-entropy rare earth zirconate ceramic material
The invention discloses a high-entropy rare earth zirconate ceramic material for a thermal barrier coating and a preparation method of the high-entropy rare earth zirconate ceramic material, and belongs to the technical field of thermal barrier coatings. The chemical composition of the high-entropy rare earth zirconate ceramic material provided by the invention is (4RE0.25) 2Zr2O7, RE is any four different rare earth elements of Y, La, Sm, Gd and Yb, and the substance amounts of the four RE are the same. Four rare earth elements are introduced into the zirconium oxide structure, the high-entropy effect can be generated, low heat conductivity, high thermal expansion coefficient and excellent molten CMAS corrosion resistance are obtained, and the zirconium oxide has wide application prospects in the field of thermal barrier coating materials.
