Abstract:
Thermal barrier coatings (TBCs) have very important applications in gas turbines for higher thermal efficiency and protection of components at high temperature. TBCs of rare earth materials such as lanthanum zirconate (La2Zr2O7, LZ), lanthanum cerate (La2Ce2O7, LC), lanthanum cerium zirconate (La2(Zr0.7Ce0.3)2O7, LZ
7C
3)were prepared by electron beam-physical vapor deposition (EB-PVD). The composition, crystal structure, cross-sectional morphology and cyclic oxidation behavior of these coatings were studied. Adouble ceramic layer-thermal barrier coatings (DCL-TBCs) of LZ
7C
3 and LC could also be deposited with a single LZ
7C
3 ingot by properly controlling the deposition energy. The failure of DCL-TBCs is a result of the sintering-induced of LZ
7C
3 coating and the chemical incompatibility of LC and TGO. Since no single material that has been studied so far satisfies all the requirements for high temperature applications, DCL-TBCs is an important development direction of TBCs.
