Alkaline earth metal ion doped rare earth tantalate or niobate thermal barrier coating and preparation method thereof
The invention relates to the technical field of thermal barrier coatings and particularly discloses an alkaline earth metal ion doped rare earth tantalate or niobate thermal barrier coating and a preparation method thereof. The coating is a multi-element gradient coating and comprises two or more different ceramic components, the volume fraction of at least one or more ceramic components is continuously increased or decreased along the gradient of the coating, the chemical general formula of the ceramic components in the coating is RE1-xM1xM2O4-x/2 (0<-1>.K<-1>, and the requirement of the thermal barrier coating for the low thermal conductivity is met.
本发明涉及热障涂层技术领域，具体公开了一种碱土金属离子掺杂稀土钽酸盐或铌酸盐热障涂层及其制备方法，该涂层为多元梯度涂层，包括两种以上不同陶瓷组份，且至少有一种以上的陶瓷组份的体积分数沿涂层梯度连续递增或递减的变化，该涂层中陶瓷组份的化学通式为RE1‑xM1xM2O4‑x/2(0
