| Abstract: | The optimum parameters of thermal barrier coating consisting of nano-YSZ produced by plasma spraying were determined through the L9 （34）testing on adhesive strength. The microstructure and correlative performance of the coating was analyzed with scanning electron microscopy （SEM）. The results of the experiment showed that the adhesive strength of the coating was 38.26MPa and the insulation temperature to reach 70 ℃ at 600℃ ,which produced with optimum process parameters,thermal barrier coating has a good environmental adaptability. |
