To solve the problem of low temperature in current aero-turbine engines, La2Ce2O7 (LCO) thermal barrier coating was prepared by using solution precursor plasma spray (SPPS) with new thermal barrier coating materials, and the influence of spraying distance, atomized air pressure and precursor concentration in SPPS technology on the microstructure and performance of LCO thermal barrier coating was analyzed. Results show that when the spraying distance reaches 35mm, the pressure of atomized gas is 100 kPa, and the precursor concentration is 0.4 mol/L, the melting state of the coating is better, with compact structure, uniform pore distribution and obvious vertical crack structure. The thermal cycle life of LCO coating prepared by SPPS method reaches 60 times. The improvement is due to the segmentation cracks in the coatings that improve the strain tolerance and effectively relieve the internal stress.
