摘要：To explore the application of fluorescence elements in the field of corrosion monitoring, Ce doped YAG (Y3Al5O12) powder and coatings were prepared. The effect of immersion duration in nitric acid on the luminescent intensity was studied. The results show that the YAG:Ce powder is mainly composed of YAG phase. The plasma sprayed coatings are dominated by YAG and YAP (YAlO3). The porosity and diffraction peak intensity of YAG:Ce coatings increase with the immersion duration in nitric acid. Meanwhile, the diffraction peak position moves for the coatings after they are immersed in the acid. The luminescent intensity of coatings increases firstly, then decreases, and finally increases with the increment of immersion duration. The luminescent intensity of coatings is influenced by the porosity, crystallinity and phase composition of coatings, etc.
