| titleOfInvention | Rare earth tantalate RE3TaO7Thermal barrier coating and method for producing the same |
| abstract | The invention relates to the technical field of thermal barrier coatings, and particularly discloses a rare earth tantalate (RE3TaO7) thermal barrier coating and a preparation method thereof, wherein more than two kinds of tantalate ceramic powder with different rare earth elements are mixed into n parts of mixed ceramic powder, and the volume fraction of at least more than one tantalate ceramic component in the n parts of mixed ceramic powder is continuously increased or decreased; and sequentially depositing n parts of mixed ceramic powder on a base material to obtain the multi-gradient rare earth tantalate thermal barrier coating. The multi-element gradient coating is obtained by designing more than two kinds of tantalate ceramic powder with different rare earth elements, namely the volume fraction of at least one ceramic component in the coating is continuously increased or continuously decreased, and the thermal barrier coating can be ensured to have the original rare earth tantalate (RE) by the method 3 TaO 7 ) The expansion coefficient is high, and the thermal conductivity is also greatly reduced. |
