Thermal barrier coatings (TBCs) are one of the effective ways to raise the upper limit operating temperature of aero-engine hot end components. Rare earth zirconate (RE2-xZr2+xO7+x/2) is considered as a candidate material for the new generation of thermal barrier coatings due to its low thermal conductivity and good high-temperature phase stability. In this paper, given to the strong performance designability, domestic and international research progress on mechanical, thermophysical and corrosion resistance of conventional alloying modified and high entropy modified rare earth zirconate coating have been reviewed based on the alloying design idea, and the prospect future for subsequent research has been proposed based on the deficiency of current research.
