摘要：In order to monitor the corrosion condition of components, plasma-sprayed YAG:Ce coating was prepared for the detection, which could develop the application of plasma spraying. The effect of sulfuric acid corrosion on the microstructure, phase composition and luminescence intensity of coatings was studied. The powder was synthesized by the high-temperature solid-state method. Microstructure and phases were characterized through using SEM and XRD, respectively. Effect of immersion time in the acid was studied on the luminescence intensity. It was found that the phase composition of the powder was dominated by YAG (Y3Al5O12). More pores could be observed in coatings with the increase in immersion time. Sprayed coatings mainly included phases of YAG and YAP (YAlO3). The position of the XRD peaks of coatings was changing during the immersion. The luminescence intensity showed the fluctuation tendency with the immersion time, which related to the coating porosity, phase composition and the migration of the diffract peak.
